AR15

JP Enterprise Silent Captured Spring

Written by: Michael Caprioli

 

  I’ve been interested in since they first appeared in 2012. It’s a buffer spring and a buffer, it’s two – two items in one!  The JP Enterprise Silent Captured Spring is genius!  The system uses a spring like a 1911 recoil spring around an aluminum rod with adjustable weights at the BCG mating side with a cone like base at the rear of the unit.  

  JP Enterprise puts a lot of research into their products and won’t release a product if it doesn’t work 100%.  Specifically, JP did a lot of research to see if there are any limitations to their SCS.

  There are two generations of the AR15 SCS – First and Second.  The difference being the first generation uses a steel guide rod, are metric (M5) and take a 3mm hex key.  The second generation uses an aluminum guide rod and a 1/8 hex wrench.

  The AR15 JP Silent Capture Spring 2-15 (JPSCS2-15), is not compatible the Primary Weapons System (PWS) old style Enhanced Bolt Carrier (EBC).   This is because the back-bore, rear opening of the bolt carrier, is not large enough to allow the guide rod of the SCS to travel through it.  This is important because the EBC guide rod is stationary and has the BCG retracts in to the buffer tube during the firing cycle the guide rod penetrates the rear of the BCG.  The PWS EBC is easily identified by the larger rear bearing area and smaller diameter back bore.  As a side notice I remember when the SCS first came out it was also recommended not for use with the PWS Enhanced Buffer 416 Tube because the tube had a slight interior taper that did not allow the SCS to fully seat to the rear.  This is not currently listed in the product instructions.

  JP also makes an AR10 second generation version of the SCS, JP Silent Capture Spring 2-10 (JPSCS2-10).  The AR10 version is not recommended for use with HK MR762 due to its larger diameter buffer, nor the DPMS GII, which will not cycle with the SCS due to its carrier design.  It’s nice that a company cares enough about its products to let you know it’s limitations before you buy it.  

  The JP 9mm SCS will work with some 9mm pistol caliber carbines, but won’t work with others. A key to look for is if the 9mm bolt has an opening large enough and deep enough to the guide rod to penetrate.  With the numerous 9mm PCCs hitting the market I can see why it’s difficult for JP to specifically state which PCC it will work for and which ones it won’t.  But I can guarantee it will work in the JP GMR-15 9mm PCC.  (Hopefully I can review one of these in the future.)  Or if you are building your own JP sells an outstanding line of 9mm PCC products.

  Both the AR15 and AR10 are available in a heavy H2 version.  The heavy H2 is recommended for use with short barrel rifles, suppressors, select-fire, piston-operated systems and when manufacture recommends use of an H2.

  If you’re not sure what system to get JP has a SCS selection guide.

  The SCS is pricey, $139.00 to $196.00, depending on type: standard, H2, with assorted spring kit; AR15, AR10 or 9mm.  Price is the main thing that kept me away from buying the SCS.  While walking the prize table at the 2017 He-Man Nationals I picked up a gift certificate from JP Enterprise that allowed me to get two Silent Captured Springs and two Low Mass BCGs.  I ordered the AR15 SCS standard version with the assorted spring kit.  The set arrives in a neat triangular shaped box.   The kit includes the SCS system, five springs, spacer and steel weights.   You can also order additional tungsten or steel weights to customize the system for your AR15 application and ammunition.  The SCS is designed to be used in a carbine buffer tube.  If you have a rifle length buffer tube don’t worry.  JP includes a spacer to be used in a rifle length buffer tube.  Simply drop the spacer in the rifle length buffer tube first, then install the SCS next.  If you have an A5 buffer tube you should be able to trim it to fit.

  A note on carbine buffer tubes.  As I stated earlier, JP does a lot of research on their products before they release them.  They also listen to feed back from their customers.  Due to the different manufactures of buffers tubes not all of them may have the same exact internal dimensions.  As a result, the SCS was seating deeper in some tubes then necessary.  JP came up with a solution to the problem.  Place a quarter in the bottom of the buffer tube and it will fill the space needed.  There should be no gap between the back of the BCG and the buffer end of the SCS.

The standard version is designed to be a low-mass system.  The weight on the system is set by using steel or tungsten sleeves.  A standard buffer uses small steel cylinders. The H buffer comes with two steel sleeves and one tungsten sleeve.  Additional steel and tungsten sleeves can be purchased to fine tune your rifle

  The five springs are rated from light to heavy and are color coded.  You must refer to the product instructions to reference the colors (so keep the product instructions with your springs!)  Changing the springs is very easy. Remember safety – wear safety glasses! You are dealing with a spring under tension and parts may fly into your eyes. Depress the weight end and place a small Allen wrench or pin into the hole in the guide rod.  Unscrew the guide rod screw.  Now remember the weights are under spring tension and now there is nothing to keep them from flying off into the oblivion that your detent pin flew off to last month. Push the weights down to relieve tension on the Allen wrench, or pin, and remove it.  Slowly allow the spring to expand until there is no more pressure against the weights.  The weights should be clear of the guide rod, remove them and then you can remove the spring.  Select what spring you want to use, and install it in reverse order.  The guide rod screw comes a dap dried of 242 loc-tite on it and should be good for about two removals and resets.

  I used the white spring because my intended purpose was a light weight 3-gun rifle with a JP Low Mass BCG.  I also have JP Adjustable gas block on the rifle length gas system.  After tuning the gas system for reliability, I ran the rifle through a series of tests.  I used both JCAA 55 grain and 77 grain long range ammo.  The cycling was flawless and fast.  I also noticed the rifle recoil was smooth and shot very flat, it did not nose dive when it returned to battery.  I think this is because of the limited range of motion of the SCS.  The forward motion of the spring is stop by the retention screw in the guide rod.  In a standard AR15 the buffer is pushed forward by the spring and the buffer hits the detent pin in the lower receiver.  This may or may not be correct but either way, the system provides smooth cycling.

  So is the JP Silent Captured Spring worth the money?  I would say, “Yes.”  I did not find anything negative about the system and saw an advantage to it.  I would highly recommend it for any higher end build.  And I think everyone needs at least one high end build AR15.

Trojan Firearms Flat Trigger

 

  Trojan Firearms is a company that is probably more know for their pistol caliber carbines. Besides this, they also make some other bits and pieces for AR style rifles. That leads us to the new single stage TFA-15S Flat trigger assembly. They also manufacture a curved version for those that don't like straight triggers. Trojan supplied one of each for review, another reviewer was sent the curved version.

  Besides being flat, this trigger has some nice touches. First off, it is a cassette style drop in. So all you have to do to install it is remove the safety and the old trigger, then it drops right in. The TFA-15 uses a shoulder bolt mounting system unlike any drop-in trigger I've seen. This eliminates the need for anti-rotate pins and for trigger pins period. Just install the screws, on each side, where the trigger pins would sit and tighten down. They also supply star washers to go on these screws. I don't think they are needed and they could possibly mar the finish around the pin holes. Another really nice touch, is the adjustment lock screw. The lock screw puts pressure on the adjustment screw so the trigger adjustment remains consistent even after long periods of use. The trigger also has 2 setscrews facing downward to lock the trigger against the mounting bolts.

  I like being able to adjust the pull weight of triggers. The TFA-15 uses the somewhat standard single screw adjustment method. Screw the adjustment screw in for a heavier trigger pull, and out for a lighter one. But, with the single adjustment screw, comes reset adjustment also. Basically when you lighten the trigger, the reset becomes lighter also, or not as positive. If you adjust the trigger too light, you don't get any reset on the trigger and have to reset it manually. I was able to adjust the trigger from 2.5 lbs to around 7 lbs. But to get 2.5 lbs, I had to measure the pull weight at the tip of the trigger. So where I normally rest my finger, it came in at 3.5 lbs. The first trigger that Trojan sent didn't pass a safety check, it would fire the hammer when the safety lever was moved to the fire position. Trojan immediately sent me a new one. They even called me to help figure out the problem. Also note worthy, the TFA-15S has a longer trigger bow length. The bottom of the triangle shaped shoe sets just slightly above a standard trigger guard. I really liked how it rested on my finger when using the lower portion of the trigger. 

  After using the TFA-15 for some time now, I really like the straight shoe. As noted above, I have it adjusted almost all the way down. When you pull the trigger really super slow, you notice what feels like creep, but is actually the sear sliding on the hammer. There is virtually no creep! Because I have the pull weight tuned down, the reset is a little spongy when releasing the trigger slowly. If I bump up the pull weight by 1/2 lb, the spongy feel basically goes away. Even though you can feel the sear sliding, it is so smooth. It somewhat reminds me of a 1911 trigger. I also couldn't distinguish any over travel of the trigger. Plus, if pulling the trigger at a somewhat normal pace, the pull just feels crisp (like breaking a glass rod). Yes, I have broken a glass rod to know what it feels like.

  Every time I review an AR trigger, I try it with my .22 lr conversion. The TFA-15 is one of the few aftermarket triggers that actually worked! Most don't have enough hammer energy to set off the rimfire cases consistently. Another great feature of this trigger is the ability to cycle the action while the safety selector is in the "safe" position. Hey, why not be able to load a round with the safety on.

  I really liked how the trigger arrived with a super smooth pull. Other triggers I have used take some break in until they felt like this. If you are looking for a decent drop-in trigger system, go look at Trojan Firearms. Their customer service is top notch, and they manufacture more than just triggers.

2A Armament Aethon Rail

  Since everyone has an AR15, or at least should, aftermarket accessories for them have become the norm. That brings us to 2A Armament. They produce a variety of products, including complete rifles, for the AR15. 2A sent me one of their 7" Aethon rail handguards with M-Lok slots.

  The Aethon rail has some interesting design features. The first one I noticed was the scalloped picatinny rail sections. Of course this helps to reduce weight, but also looks very nice. The Aethon features a full top rail, that lines up with the receiver nicely. Under the top picatinny rail there are lightening holes, which also help vent heat away from the barrel. At 90°, 180°, and 270° are the flats with the M-Lok slots. Since this is a 7" handguard, there are only 2 slots per side. In front and behind the M-Lok slots are holes for QD mounts! Between the flats on the handguard, 2A has reduced more weight by milling out an angled half circle style design. Also the top picatinny rail has "T" markings on it.

  Installation of the Aethon rail is pretty straight forward. I'll run you through the simple method. After taking off the old parts. Just install the 2A Armament titanium barrel nut per specified torque, line up one of the cut-outs for the gas tube and the barrel is tightened back on. I used my armorers wrench and it worked just fine. Now here is one of the niceties of the Aethon. To install the handguard, you just slide it over the barrel nut and align the top rail with your receiver. Then you just tighten down the four angled set screws, 2 per side, and your done. The way the barrel nut is designed, along with the angled set screws, is what makes this so easy. A warning, do not over tighten the set screws as they are going into aluminum and could possibly strip out fairly easy. I just put blue threadlocker on them and called it a day.

  The Aethon rail saw plenty of use. Partly because the rifle I installed it on, wasn't working properly. This had zero to do with the Aethon. I will say that because of the small internal diameter of the Aethon, it does get very warm when shooting quickly, so much that I wouldn't recommend it for a registered full auto, unless you always wear gloves. Other than that, the Aethon performed great. I liked the smaller diameter of the Aethon, it allowed me to get a good grip around it to help reduce muzzle jump. If you have really large hands, you could probably wrap them all the way around this handguard. Because this is a 7" handguard, it is very sturdy with no flex whatsoever. There are also no sharp edges anywhere, even where the set screws lock the handguard on. My only complaint is that it only measures 6.7" long instead of 7", leaving a little gap between the end of the handguard and the fixed front sight post. 

  2A Armament has done an excellent job with the Aethon handguard. It is a deep black anodizing, so much that it is much darker and shinier than my receiver. It is fairly lightweight and installs easily. If your in the market for some nice AR parts, go take a look at 2A Armament.

Smoke Composites Carbon Fiber Handguard

   As many of you know, carbon fiber seems to be popping up everywhere. Smoke Composites is one of those companies. They recently started making carbon fiber parts for AR style rifles and pistols. Their history of making parts for the defense industry, has had a definite benefit for those of us looking for lightweight AR parts. I will take a look at their 12" handguard. 

  Smoke composites sent me one of the 12" M-Lok handguards to review. The first thing I noticed was how spectacular this handguard looked. It has a cool, non-symetrical, look to it. Not the standard grid pattern one would expect. I also noticed the quality put into the handguard. But then I picked it up, and wow, it is light. 

  Now it's on to the tech specs. When I said it was light, well, it weighs in at 7.3 ounces complete with all the hardware. It might not be the lightest, but accessories can easily be added by using the M-Lok slots, something other manufacturers don't offer in carbon fiber. Speaking of M-Lok, it uses the standard 5 slot M-Lok rails. The handguard has 4 M-Lok slots on each of the 8 45 degree sides. The slots aren't evenly spaced, they are grouped by 2's and then a space between the 2 groups. Also the slots on the top, bottom, and sides are more toward the front of the rifle. With the 45 degree ones set back slightly from the front of the rifle. Construction is from 35-50 carbon fiber and 7075 aluminum, so as far as I could tell, good stuff. At 1.88 inches outside diameter, it felt really good in the hand. I thought maybe the smooth carbon fiber would be hard to grip, but my hand seemed to kind of dig into the slots to provide grip. Smoke Composites forms a ring at the front of the handguard, I would guess to protect the front from getting chipped, it would be quite thin otherwise. The inside of the ring measured 1.53 inches, so some suppressors will fit inside the handguard. Don't worry about heat when doing this, the carbon fiber mitigates heat great! 

  Installation of the handguard is pretty straight forward. Make sure the firearm is unloaded and safe. Once you have removed your old parts, take the supplied barrel nut and tighten it over the barrel to normal specifications. Line up one of the threaded holes of the barrel nut, with the top of the receiver. Now put your low profile gas block and gas tube on. Then slide the handguard over the barrel nut. Loosely install the 6 supplied screws into the holes. Line the handguard up, and tighten down the screws. Now your done with the installation.

  When using the handguard, I found it worked nicely. The rifle swings fast, but also stops pretty well. If you are looking at getting this type of handguard, I would recommend getting a lightweight stock also because just the handguard alone might throw the balance of the rifle off. I did try this upper on a rifle with a standard M4 style stock and one with a Smoke Composites' stock. The M4 didn't seem to swing as well as the carbon fiber stock did, at least for me. One option I would have liked to have seen is the addition of some QD mount holes built into the handguard. I may drill some myself. When shooting fast, I did notice that the carbon fiber did an excellent job of not heating up.

  Smoke Composites is doing some awesome stuff with carbon fiber. This handguard is just one of them. Plus, if you want a custom length, they can do that also. I think these guys are going to be a company to keep an eye on. Great service, great products, and made in the United States of America!

GunTec AirLite Minimalist AR15 Stock

  A little bit ago I did a review of the GunTec Air Lite handguard. Well, they were also kind enough to send one of their AirLite stocks for review also. This is GunTec's minimalist AR15 stock.

  The first thing you will notice about the AirLite stock is how good it looks. It is basically a buffer tube, with spiral fluted cuts down the tube. Then it has a textured aluminum buttplate attached with a clamp system. Also supplied is a rubber buttpad that slips onto the buttplate, a nice touch if you don't like the textured plate, plus it adds another 1/4" of pull to the stock. The stock in only 9" long when attached, which is a little short for me, and thus gives the rifle about a 12" length of pull total. Guntec does offer another minimalist stock with a 1" longer length. I didn't have any trouble shooting the rifle with the shorter length, and since this is their "Lite" offering, I can only speculate that this is how it is suppose to be. The stock would be really nice on a SBR build if you wanted a fixed stock.

  I was really impressed by how sturdy the AirLite stock is. Once mounted, it doesn't flex at all, and gives a nice sturdy shooting platform. With adjustable stocks, I always seem to feel a little bit of movement under recoil. Being that this is a fixed stock, I don't get that "feel." The buttplate is also adjustable for cant. So once the stock is installed, loosen the clamp bolt and twist the buttplate to the desired location and tighten the screw back down to clamp it in place. I like this feature because you can set the stock to fit your shoulder pocket, not just straight up and down like most stocks.

  Now we can get onto some of the specs. The stock comes complete with a castle nut, an ambidextrous single point sling plate, 3 ounce carbine buffer, and chrome silicone recoil spring. The whole thing is made from 6061 aluminium. It weighs in at 9.3 ounces on my scale, without the spring and buffer. My mil-spec buffer tube and M4 style stock weigh 11.8 ounces on my scale. So your saving 2.5 ounces over a stock M4 by choosing the Guntec AirLite stock.

  As I said in the handguard review, If your looking for some good AR products, go check out GunTec. This Minimalist AirLite stock is a nice usable piece of equipment for your AR15.

Guntec 15" Air Lite Handguard

   As one can probably guess, this is about Guntec's new 15" Air Lite handguard for the AR15. I received the handguard about 2 months ago and have been using it ever since. Guntec has been around since 1989. They make tons of accessories for AR15's, AR10's, AK's, and even more. 

Shown with an extra M-Lok rail on bottom and a rubber M-Lok cover

  The Guntec hanguard that I received was in M-lok. For you keymod fans, they make them also. Now the first thing I would like to mention is how thin the handguard is. If you like them thin, you'll love this handguard. It measure 1.5" wide, 1.975" tall, and has an inside diameter of 1.34". It also has a built in full length top picatinny rail. I will mention that although it is M-Lok, it only has 3 m-lok slots each on the sides and bottom, toward the very front of the handguard. This would be 3, 6, and 9 o'clock.  The rest of the handguard has cut out triangle patterns to reduce weight. 

  Now, this Guntec handguard is light. On my scale, it weighed in at 9.6 ounces complete with barrel nut and screws. Remember, this is a 15" handguard with a full top rail, so this is quite good. The barrel nut is also aluminum, which helps with the weight. 

  Installation of the Air Lite was pretty straight forward. Which is good since it didn't come with any instructions. Once all your old parts are off. Slide the barrel nut on and tighten as normal. If the screw holes that hold the handguard on don't line up, remove it and put one of the supplied shims in it and try again. My kit came with 4 shims, I only had to use 1 to get the holes to line up. Guntec also lists a crowfoot wrench for the barrel nut, buying the wrench will make life much easier. Next install the gas block. I only mention this because you will need a low profile one, and smaller is better in this case. Then slide the handguard on. Line it up. Then install,  and tighten down, the supplied screws. Thread locker is probably a good idea. And as always, safety check the rifle when finished. 

  Depending on where the gas block is located, you might run into some accessory mounting problems. Since the handguard is so thin, the screws on the m-lok parts may run into the gas block. On a mid-length or rifle length gas system, one set of m-lok attaching slots will not be usable. The inner part of the handguard is just too close to the gas block. Cutting down the screws won't even work. If you run a carbine or shorter gas system, you won't have this problem.  

  After shooting this handguard, here is what I found. Being that it is very thin helps if you shoot thumb over bore, or if you have smaller hands (think children). I did notice that it heats up faster than some of my larger diameter handguards, but really this is only a problem after 3 or 4 30rd mag dumps. It has no sharp edges and is flat on the end so it doesn't get caught up on stuff. It is not what you want if you plan on putting a suppressor under it (too thin). It is quite sturdy. And it comes with rubber m-lok inserts. 

  If you are looking for a light handguard, this Guntec might be for you. I would like m-lok slots all the way down, which they make, just not in the Air Lite version. The price is reasonable. It looks good and even comes in many different colors. Go check out Guntec, they probably make an accessory for you.

ODIN Works O2 Lite KeyMod Handrail

  Back in Episode 136 of the Podcast, we discussed the Odin Works O2 Lite handrail. I was intrigued by it, so I contacted Odin Works to get one in for review. They responded quickly and sent me a 12.5" KeyMod O2 Lite rail. Odin Works makes a vast assortment of AR related products for you to choose from.

  The first thing I noticed about the O2 Lite handrail is how lightweight it really is. When I took it out of the box, it was really noticeable. It weighs in at 8.1 ounces complete with the barrel nut system. Odin did a really nice job of reducing the weight by putting in tons of scallop cuts on the forend. These cuts are kind of hex shaped, with some of them being elongated. I would guess the name "O2" comes from the cut outs looking like an Oxygen molecular drawing. And, of course, it free floats the barrel. If one were to hit the edge of one of these cutouts, you might be able to bend it down. It wouldn't bend far enough to cause any functionality problems, just cosmetic ones.

  Now I'll get on to some of the technical specs. The O2 rail is made from 6005-T6 aluminum that is then anodized black. Since they sent me the 12.5" rail, that is how long it is. It has an outside diameter of 1.8" wide and 2.16" high. The reason for it being taller is because it has a small rail section built into the top of the handrail, but only at the front and back. So I would call it a hybrid rail. The top, between the 2 rail sections, does not have any way to mount a rail section between the front and back rails. The inside diameter comes in at 1.6", so plenty of room. Along with the O2 having KeyMod slots along the 3,6, and 9 O'clock positions (MLok is an option also), there are QD attachment points, at the front and rear, at 3 and 9 O'clock. A 5 slot KeyMod picatinny rail also comes with the forend. It is not mounted, so one can use it as necessary. Of course, any Keymod accessory should work also.

  Mounting the handguard is really pretty easy. If you know anything about removing AR barrels, you shouldn't have any problems. Basically, remove the old barrel nut, gas tube, and gas block. Then, screw on Odin's forend adapter. align gas tube hole, insert gas tube alignment pin (supplied), put Vibra-Tite (reusable threadlocker) on barrel nut threads, screw on barrel nut, and tighten to 40-50 ft-lbs with a 1-1/4" crowfoot wrench. Odin Works sells a crowfoot wrench, I would recommend getting one with your order. Reinstall the gas tube and gas block. Slide on O2 Lite handrail, tighten on with 6 screws and supplied allen wrench. You now can go put some rounds down range.

  Immediately after installing the O2 Lite forend, I could tell a weight difference. I think this is probably my new favorite handguard. It is comfortable to hold on to. The looks are fantastic. It is really light. And it comes in various lengths. Odin Works did a fine job creating this piece of engineering! If you are looking for anything AR related, go visit Odin Works, I doubt you will be disappointed.

These are a GREAT product. I use to use the Carbon Fiber ones I could get but after getting this one I am going to use them on all by rifles from now on. They feel great and the COOL fact is good also. All that aside they function well and are very lite which make them perfect for a carry rifle especially for hog hunting or any hunting for that matter. Great product you all have.  Thanks and thanks for your fast shipping too.

Lucid L7 1-6x24 Rifle Scope

   Now that the review of the Lucid L5 4-16x44 is done. It is time to move on to the L7 1-6x24. The L7 is Lucid's quick adjustable, True 1x to 6x power optic. Lucid was kind enough to send me the L7 when they sent me the L5. 

upload.jpg

  Lucid's new L7 optic comes with some pretty nice features. First up, it has a one piece 30mm tube that allows plenty of light through the 24mm objective lens. Second up, the variable power adjusts from a true 1x to a usable 6x. The L7 also comes supplied with an optional throw lever to adjust zoom. If you opt for the throw lever, just install it with the supplied allen wrench. The L7 uses Lucid's P7 reticle set on the second focal plane. At 1x, one can use the scope as a pseudo red dot. Except the L7 has an illuminated blue inner reticle, yes Blue. I found the blue to be an excellent choice. I was able to pick the reticle up on all different color backgrounds. When it's not illuminated, you will see the full MOA etched reticle, so even if you happen to have a blue target, it will still be noticeable. The marks on the reticle are spaced at 8 moa apart. If using on a 5.56/.223, they really don't allow for bullet drop. But if using something big and slow, like the 300blk subsonic, they work quite well.  The throw between 1x and 6x is about 180 degrees. The MOA reticle is calibrated to the 6x magnification setting. 

Reticle Illumination

208gr .300Blk. 50 yd zero at 6x

Standard 5.56 55gr. 50yd zero at 6x

  Now, my favorite thing about Lucid scopes is the adjustment knobs. To adjust the reticle up/down or left/right, one must first pull up on the adjustment knob. Then turn it, and push it back down. This locks the turret from moving. The turrets have a very nice tactile click to them. On the L7, each click is 0.5 or 1/2 MOA. To set the turrets to zero, just loosen the screw with the supplied allen wrench, pull up even farther, turn to zero, push back down, and tighten the screw. Next to the turrets, on the left side, is the brightness knob. It also holds the CR2032 battery. There are 11 brightness adjustments. I would have liked the reticle to be brighter,  because in daylight it is hard to see the illumination.  

  I mounted the Lucid L7 1-6x on a 16" AR. Which is really what the L7 was primarily designed for. The first thing I noticed was how clear the optic was. I have seen 1-4x optics in the same price range that aren't this clear! The scope also comes with flip covers. A nice touch, but the covers are pretty flimsy. 

  Lucid has done a reasonably good job with the L7 1-6x24. It is very clear, has Lucid's excellent knobs, has blue illumination, and is a true 1x. They only thing I would change, is the MOA hash marks. Maybe make them 2 or 4 MOA apart to better work with the 5.56/.223 cartridge. Give Lucid Optics a look, they may have something worth sighting through.

Outstanding Optic

I wanted a 1-6x optic that wouldn't break the bank but also wouldn't be something that I knew was "cheap". A friend suggested the L7 and even after reviewing the website I still had some questions. A quick call to Lucid...and a chat with the president of the company, answered them. When the optic arrived, I was glad to see that it felt solid and rugged and wasn't something that would fall apart if it got a few dings and scratches. The glass is clear and the reticle is crisp. A word about the reticle...I like how the various steps on the "ladder" are a fixed distance so not only does it operate as a BDC, it also will function as an ersatz range finder.

Warne R.A.M.P. Scope Mount Review

warne1 The Warne R.A.M.P mount is a 1 piece scope mount for AR-15 style rifles, or any rifle that has a picatinny rail and needs a forward mounted optic.  R.A.M.P stands for Rapid Acquisition Multi-Sight Platform. It gets the multi-sight part because besides having built in rings, it also has 2 45degree angled mounts.  These mounts allow you to install a small red dot sight on one of the canted rails.  One could mount Iron sights on these also, but would then need the optional mount for the front sight to attach on.  The RAMP mount comes in three sizes for most needs: 1inch, 30mm, and 34mm.  I have the 1" version, but they are all essentially the same.

The 45 degree mounts are really what sets this mount ahead of its competition.  With the ability to mount something small on either the left or right side of the scope, it will appeal to both left and right hand shooters.  If you decide not to use one side or the other, or neither, the angled mounts are removable with 2 socket head screws on each.  Because of the added mounts, and space to attach the mounts, it is not the lightest mount out on the market.

Another nice feature on the RAMP mount is the 1/2" hex screws on the mounting base.  They are to be torqued to no more than 65in/lbs.  Also a torx style allen wrench is supplied to tighten down the top of the scope rings. There are 2 T-15 torx screws per side and should be tightened in an x pattern.

I really like the RAMP mount.  It puts the scope at the correct height and the proper eye relief.  With the option of adding a small red dot if one desires. The only negative I can see with the mount is the weight, but it is a very sturdy mount.  If you are in the market for this style mount, you cant go wrong with the Warne RAMP.

Bought one of these for my RRA LAR 15 to use with a Leupold Mark AR on top and a Leupold Deltapoint on the side. Got it, opened it, and could not have been more impressed with the build of this mount! Rock solid craftsmanship. Placed it on my AR and it holds tight and sits perfectly. Take it off...no problem. Put it back on....exact return to scope zero. Just bought another one for my RRA LAR-8! Get one, or two, you will not ever want any other mount!

Jkrispies on Brownells 5/5 stars. Great mount for a 45 secondary mount.

A little heavy (even with the side mounts removed) if you're not going to use the 45 degree option, otherwise typical Warne quality, which is the best I've found out there. Only warning I'd give is to do some research before buying this-- will your Mini-Red Dod Sight clear the bell of your primary scope? Ironically, I think the perfect use of this scope with a 45 degree mount would be on a monolithic receiver (think SCAR) and the mount backwards. Height is perfect. If you don't foresee yourself ever using the side mounts, I would recommend going with the Warne SKEL mount, which is the same mount as this minus the extra attachments, thus reducing weight significantly.

MT Chamber Flags

MT Chamber Flags

Gun safety is the most important foundation to our hobby. Sometimes a product comes along that is so simple and easy to use, it makes using firearms safely almost idiotproof. I say almost, because anything can happen. However when handling a firearm, at least a semi-automatic handgun or rifle where accidents and negligence are more prone, and chamber flag can guarantee that a firearm has been inspected, is cleared, and is safe to handle.

MT Chamber Flags

Chamber flags aren't a new invention, they've been around what seems like forever. Often they will come packaged with a firearm from the factory, and many gun owners either leave them in the box, or cast them aside like the safety locks they probably have dozens of. Even though many gun owners don't use chamber flags, many shooting ranges require flags to be used so that Range Officers or other shooters can all verify firearms on the bench are clear, empty, and inert before proceeding downrange to check targets, with the peace of mind there aren't any accidentally loaded firearms pointing at their backs.
I believe the generic chamber flags are inherently too small, serving more as a chamber block than an actual flag to visibly signal the firearm's status around the vicinity. Fortunately there is a better designed alternative chamber flag that does a much better job.

MT Chamber Flags

M-T Chamber has created a chamber flag that is highly visible because of it's length, and integral pull handle that increases the visible surface area from 360 degrees around the firearm. MT Chamber flags also come in two caliber ranges, fitting either 380-40 caliber chambers with the SBT 380/40, or 45 auto and .223 (AR15) chambers with the SBT 45/AR15. This gives the user the ability to toss either or both chamber flags in their bag and utilize for nearly any semi-auto firearm while at the range.

MT Chamber Flags

Chamber flags aren't just useful at the range. FFL's and gun shops often use a chamber block or similar device to keep guns in the glass counter clear and safe, and easily inspectable at a glance. Also law enforcement need ways to keep found or seized guns cleared or identified as inspected and cleared in a fast efficient manner so they can do the task at hand. The MT Chamber Flag accomplishes all of the above much better than other flags on the market today.

 

 

MT Chamber Flags

 

I tried the MT Chamber flags in just about every semiauto firearm I own, and while the pros are very apparent (high visible, multi caliber compatibility) there are a few cons that keep my review from glowing as brightly as the flags themselves. The plastic construction is very flexible and somewhat soft. In fact, if you let the slide / bolt close with the full force of the spring, there will start to be chew marks into the back of the flag. While some normal wear and tear won't effect the performance of the flag, I would recommend assisting the bolt or slide close more softly to get the most longevity for your dollar. My only other gripe is that the flags don't have any indication as to their caliber range incorporated into the mold. Instead of having the logo and website on both sides, it would have been nice to have the model number or at least calibers on the flags themselves. Other than that, the MT Chamber flags are a decent evolution of the safety device that many of us overlook.

Sig Sauer SB15 Pistol Stabilizing Brace

Sig Arm Brace If you've been out of the tactical neighborhood for a bit, you maybe scratching your head at all these short barreled AR15s with arm braces that are scattered around magazine spreads and internet blogs. You may be wondering if shooting one handed is the new tactical hat trick. Not quite, but they have become very popular with AR-15 owners who are very proud of their "pistols."

Let me back up a bit. The original purpose of this arm brace is to aid those who are unable to shoulder a rifle effectively, because over either an injury or medical disability. In fact this product was designed by a US Veteran who was looking for a way for disabled vets to still be able to control and shoot rifles safely.  Mounting this on your AR-15 rifle (or AK47 as a different model) does not change its legal definition, and allows users to raise the firearm by anchoring the brace to your forearm. Needless to say, the weight of your rifle and your arm strength play a strong role in your success in using this product. However for those who are unable to fire a rifle for any number of physical obstacles, this stock is a game changer.

Now, I will get into why everyone else, myself included, are purchasing the Sig Sauer SB15 Pistol Stabilizing Brace.  In short, the ATF has ruled that installing this "brace" onto an AR Pistol does not alter the firearm's classification as a "pistol," and thus avoiding the classification of an SBR (short barreled rifle). So basically if you have an AR Pistol and you install this arm brace, it lets you legally own something that is similar to an SBR in handling/shouldering terms, without filing a Form 4, paying for a tax stamp, waiting between 8-12 months for your stamp and approved paperwork, AND not being able to transport the firearm in between states without notification of LEO.

Now I'm not a lawyer, and NFA laws are not something you want to misunderstand due to every gunshop employee you could talk to have a varying explanation.  Even as you are reading this, my understanding of whats correct and incorrect may no longer be the law of the land.  So I will not go deep into the Do's and Don'ts of AR15s and AR Pistols. Just consult the ATF website and make sure your SB15-equipped firearm is in NFA compliance if you are thinking about a barrel shorter than 16 inches.

 

sigbrace2

I actually found the brace difficult to use. The elasto-polymer is uncomfortable if you just shove your arm through the brace. I also found it impossible to straighten my arm enough to use sights. I believe this is a downside to installing the SB15 on an elongated pistol buffer tube, like the KAK industries Super Sig tube. It positions the brace farther back on your forearm, and decreases the angle at which you can align the pistol straight ahead.  Also an optic like a red dot is required as you won't be able to use iron sights correctly with the appropriate eye relief.

However, this brace has an unintended benefit that probably makes up approx 90% of sales, being able to shoulder it like a stock, without it actually being a stock. With the official ruling and letter that comes with every SB15, the ATF has ruled that shouldering the arm brace does not magically make your pistol and rifle, and then back to a pistol when it is un-shouldered... that would be ridiculous and arbitrary! That is the reason why the brace is so popular.  I have tried firing an AR Pistol using only a naked buffer tube, and it was awkward and uncomfortable. The SB15 isn't as ergonomic as an actual stock, but the increase accuracy from a more traditional shooting technique and the legal benefit of this item make it worth the investment for those who desire a short barreled version of an AR-15 without the red tape. The cheek weld isn't bad, nothing to write home about but its better than nothing. Those who often wear armor (plate carriers, or other bulky tactical garb) will also appreciate the shorter LOP.

My only other gripe is the color of the FDE model. It's nowhere close to the other "Flat Dark Earth" furniture I have of my firearms. Not even close to coyote brown.  Why is it so difficult to nail down a consistent color for all manufacturers? OD Green wasn't the same across the board either, but there seems to be so many different shades and hues with the title of FDE that heavily contrast from each other. I would call this color "Flat Dark Baby Puke." Okay, graphic designer rant over!

What others are saying?: "As far as the intended purpose of the brace: it's completely moronic. you can't really look down the sights, can't manipulate the weapon, and can't really use the controls. Forget about scoring good hits on target. I guess I understand the idea, but it just doesn't work. We all know what the real value of this brace is, and it functions far better in that regard.

Pros: You can skip the ATF wait, tax, and NFA paperwork and have what I would consider maybe 80% of the functionality of an SBR. It actually offers a pretty good cheek weld, if you don't mind how close in you have to tuck your carbine. Rubber is solid enough to function in the "traditional" sense. The stock is on the tube very tight, it took me and another meathead friend of mine to pull it off. I haven't tried to mortar the gun yet but I think the brace would probably do just fine. I consider myself to be stronger than most and it took an enormous amount of force to push the stock as far down as I did.

Cons: It can turn on the buffer tube because it isn't locked in at all. Sig should find some way to lock this in so it can't turn. It wouldn't be any different functionally if it went on a traditional buffer tube, but I'm sure the ATF in all their wisdom would never go for that. It is sold feeling piece of gear, but it's still rubber. You'd probably be **** out of luck if you were trying to squash somebodies head with it as opposed to a normal stock. A QD swivel also would have been nice, but I don't really expect that type of thing from Sig, especially on a product like this. Maybe they'll release a second gen of these at some point, but I kinda doubt it. Another con is that the stupid thing costs $140, more than almost every buttstock on the market, and most of your NFA tax stamp cost. You also have to pony up cash for the pistol buffer tube. The most obvious con is that the brace comes in black and not tan, which makes it infinitely less tactical." Tzook user, M4Carbine.net Review

Crosman MAR177 PCP AR-15 Upper Receiver Conversion Kit

MAR177-PCP.jpg

Crosman MAR177 PCP

Have you ever considered a conversion kit for your AR-15 platform rifle or carbine? Perhaps a 22LR kit that snaps onto your lower receiver and allows you to shoot the economical 22 Rimfire. How about a conversion kit that shoots an even more economical round and keeps your guns clean?

Let me preface this with telling you that I am NOT the target market for this conversion kit.  This product is designed for the precision rifle competition shooter, so from my point of view the price point was a real shocker at first. However, I do see value in more than just a competition setting. This could be a really good training option for any AR-15 shooter. I would compare it to a 22LR conversion in some ways. Yes, it’s more expensive, but the ammo is way cheaper than even 22LR. You can purchase 1,250 (177) caliber pellets for about $14. So over time you may break even with a 22LR conversion kit. One of the big benefits of an air rifle upper is that they are very CLEAN, you will rarely, if ever, have to clean this. Not something you can say about 22LR conversion kits.  My one big issue is that fact that you have to manually charge the action every time you take a shot. I’m sure this is not an issue for the intended users since they mostly shoot bolt guns in small bore competitions. Overall I'm very pleased with this conversion kit, it leaves a smile on my face each time I shoot it.  Whether you're training for 10-meter rifle matches, plinking cans or shooting apples, I would recommend taking a serious look at the Crosman MAR177.

Claim to Fame: The MAR177 conversion kit replaces your existing AR-15 upper receiver and converts it into a PCP(Pre Charged Pneumatic) .177 caliber competition air rifle.  Designed to support 10 meter match air rifle competition.

I need it now! Availability In stock at the above places as well as: Amazon.com for currently $600

Our Rating If the price point was a few hundred dollars less I would give this 9 stars out of 10 since it would open it up to the 22LR conversion market with comparable price points.

+ Rifled Lother Walther steel barrel + Good alternative to a 22LR conversion kit + Fun to shoot + Very accurate for even a rifle noob like myself + Velocity up to 600 fps + Built in pressure gage

- Very heavy and bulky - Must be charged from a scuba tank or a VERY high pressure hand pump (1,000 to 2,900 psi) - Expensive
