Primary Arms SLx 3x MicroPrism

, , ,

  Many years back, fixed power optics were very common. They tended to be larger in size when compared to say, a standard tube style red dot. Fixed power optics have come back around thanks to the small magnified prism optics like the Primary Arms SLx 3x MicroPrism. The SLx is so much lighter and smaller than the fixed power scopes of the old days. The SLx 3 power prism also gives you plenty of new benefits that just weren’t available back in the day. So let’s welcome in the small, fixed 3 power optic of the future. Now offered in FDE to match all your tactical needs.

  Primary Arms set the bar high when they released the 1x MicroPrism, then they raised it with 3x and 5x models. They sent me out the 3x version in FDE. Fixed power optics have their place in the shooting world. With the SLx 3x you get a super small package size plus some magnification to see targets at mid range distances. Since the magnification isn't super overpowering, you can still use this optic up close. It also doesn’t weigh much, tipping the scales at just about 8 ounces. For being in Primary Arms’ SLx line of products, you get an exceptional value with super clear glass. 

  One of the great aspects of the Primary Arms 3x MicroPrism is its reticle. Primary Arms uses one of their ACSS reticles, or “Advanced Combined Sighting System”, in the SLx 3x. In particular, this is the Raptor ACSS reticle. The ACSS Raptor gives you ranging, bullet drop compensation, wind holds, and moving target leads, all in a simple to use red colored reticle. The reticle has an illuminated horseshoe around a center chevron (think triangle instead of dot). The ranging, wind and bullet drop then take up the reticle below the center chevron, these compensations are not illuminated. The illuminated section has 13 intensity settings, 3 of which can be used with night vision. Using the ACSS Raptor is really easy. The large horseshoe lets you shoot up close targets quickly, even though the SLx is a 3 power optic. The chevron and stadia then give you precision shots out farther. I found the reticle to be a good compromise between close and far range targets. Being a 3 power prism sight, I am a little slower at shooting an array of close in targets, but I am more accurate when out at farther distances. Primary Arms did a good job with the reticle on the SLx 3x MicroPrism. The illuminated part of the reticle is “daylight” bright, even in direct sunlight. If, for some reason, it does wash out a tiny bit, the reticle is etched into the glass, so you get your typical non illuminated black reticle anytime, even if the battery goes dead. 

  If you are worried that the SLx 3x MicroPrism won’t work for your firearm, don’t fret. Primary Arms gave the MicroPrism plenty of mounting options, and they all come with the optic. The SLx manual states 8 different mounting heights. This is from essentially rail height (1.1” to center of prism) to 2.075” to center of optic. There is also one other option. If you have a carry handle AR, fixed or removable, the SLx MicroPrism will mount directly to the carry handle. If you want to use a different mount than the ones supplied, The SLx MicroPrisms use an industry standard “Mini Prism” footprint. 

  One aspect of the Primary Arms MicroPrisms is their exceptional clarity. For the price you pay for one of these, you get extraordinary clear glass. I’ve also found that even though the eye relief is stated at 2.7”, it is very forgiving. Since the MicroPrisms have an etched reticle, they also don’t have the clarity problems for people with astigmatisms. Making the ACSS reticle super clear. Being that this SLx MicroPrism is 3 power, it also has a decent field of view at 100 yds, which is 38 ft. So you will see a 38 foot wide circle, when looking through the prism sight, at 100 yards. 

  The SLx 3x MicroPrism also has a few other features that need mentioning. First off, it uses Primary Arms’ “AutoLive” motion sensing on and off. So when you pick up the SLx prism, the reticle turns on at whatever brightness the knob is set to. After not sensing any movement for a few minutes, the optic goes back into a hibernate mode, where the reticle is off. Once you move the optic, the on cycle starts again. I absolutely love the AutoLive technology and it works fantastic on the Primary Arms’ MicroPrisms. This AutoLive also gives the 3x MicroPrism a battery life of around 29,000 hours. Which is fantastic for any magnified optic. The windage and elevation adjustments are also protected from being hit or accidentally turned. You can even adjust them using the rim of a cartridge. I’ve done it, it’s easier than looking through the range bag for a tool. 

  The Primary Arms SLx 3x MicroPrism fits in well for a fixed mid range optic. It allows close range work too. Everytime I look through one of the Primary Arms MicroPrisms, I am surprised by the optic clarity. Add in the AutoLive function and you have a great combo of features. So if you are looking for a small fixed 3 power optic, check out Primary Arms’ line of SLx MicroPrisms.

WOW, PRIMARY ARMS REALLY GOT IT RIGHT WITH THIS ONE!

This is Primary Arms Optic number 3 for me, but will definitely not be the last!

I got this optic for a lighter weight, simplified build. Got tired of dealing with heavy rifles and playing around with LPVO's, so this became the obvious choice. I was a bit skeptical about the fixed 3x magnification, but after zeroing it this afternoon I didn't have any issues taking shots at 100 and 150 yards, ran out of daylight to try any longer distances. However, I don't think I'll have any issues making hits out to 300–400 yards.

I know this is a "budget" priced optic, but I'm pretty impressed, the glass is really clear. The reticle is sharp and informative without being cluttered like so many optics are. Oh, and speaking of the reticle, the illumination is very bright on the maximum setting, much brighter than my LPVO and gen 1 Cyclops prism. I would say it's daylight bright, I actually ended up dropping it down to the 9th or the 10th setting to use during the day.

Athlon Midas TSP1 Prism

, , ,

  I’m starting to convert some rifles over to 1x prism sights from red dots. This is because they offer a reticle without the need for a battery. Thus, the Athlon Midas TSP1 prism sight was right up my alley. Prism sights usually have an illuminated reticle option. As does the Athlon TSP1. The Athlon Optics Midas TSP1 prism sight has been out for some time now, I just finally have one I’ve been using, for about 3 months, with good results.

  Let’s start by why I am converting over to prisms. The main reason for this is that, if for some reason the battery happens to die, prism sights have an etched in reticle. Similar to your typical scope. Some prism sights, as with the TSP1, have a non-magnified option, or 1x. This makes them an ideal replacement for your everyday red dot optic. Prism sights are also usually pretty compact.

  The Midas TSP1 comes feature packed. Like any good scope these days, it has all the fancy lens coatings, is nitrogen purged, fog proof, shock proof, and waterproof. The TSP1 has a 21mm objective lens that gives good light transmission. It even comes with both hi and low mounts. Zeroing adjustments are made in 1 MOA click increments by using the top side of the turret caps. Just unscrew the cap, flip it over, and the flathead built into the cap fits perfectly into the adjustment screw slot. Lastly, it uses a single AAA battery for the reticle illumination.

  Most prism sights aren’t as small as a comparable red dot. However, the Midas TSP1 is not much larger than your current, tube style, red dots. For one, the TSP1 is only 2.7” long. Height is always determined by what mounting base you have on it. But with the high base, it measures 2.5” to the top of the battery compartment, from the mounting rail. I measured the width to be about 1.9”, this is from the battery compartment to the outside of the adjustment buttons. As you can see, it’s not very big at all. It also isn’t very heavy, weighing in at 6.25 oz’s. 

  Now for the most important part, the reticle. The Midas TSP1’s reticle is top notch. It is mainly calibrated for 223/5.56, but should work reasonably well with other calibers. For reference, I mounted it on a 5.56 AR15. The reticle design works really well. It is a horseshoe style with a few usable differences. The outer ring is 66 MOA, or the equivalent of an average size human at 100 yds. In the middle of the ring is a 3 MOA dot. Sight the 3 MOA dot in at 50/200 yds for the rest of the holdovers to work properly. Below the 3 MOA dot, is a 2 MOA dot. This is your 300 yd aiming point. Having a smaller dot below the main dot may seem odd, but it isn’t. The smaller dot actually makes it easier to see your 300 yd target because it doesn't obscure it as much. Below that dot, is a vertical line with a couple of hash mark lines. The top of the line is your 500 yd aiming point. It is also your human height range estimation for 300 yds. The wings on the edges of the reticle really just let you know how level the gun is, or where the center point is for range estimation. The actual MOA numbers for all the dots and lines are in the Midas TSP1 manual, or online, if you are curious. The TSP1 also has a fast focus eyepiece to get that reticle crystal clear.

  The Athlon TSP1’s reticle is also illuminated. But not just your normal red illumination, the TSP1 also has green illumination. Most other prism sights only give you the option of one color. One can switch between the two colors by pressing both the up and down brightness buttons at the same time. I really like the options of green or red. I usually leave the TSP1 on green, as the reticle is clearer for me in that color. Not to be misunderstood, the red illumination is also clear, but I prefer the green in this case. To initially turn the illumination on, just push the brightness up button. To turn it off, hold the brightness up button for 3 seconds. Once it’s on, just use the +/- buttons to increase or decrease the reticle brightness. There are 10 brightness settings to choose from. Both colors are daylight bright and neither washed out for me in direct, bright, sunlight. The Athlon TSP1 also has a 6 hour auto off function. So if you haven’t pressed any buttons in that time frame, it will turn off. The TSP1 does not have an auto on function. Remember, it has an etched reticle, so you will still have an aiming point. Of course, once you turn the TSP1 back on, the brightness is where it was last left. The soft touch brightness buttons are large enough that I don’t have trouble using them, something I can’t say about some of the other optics I have used. 

  I am really enjoying the Athlon Midas TSP1. It is super clear. The etched, illuminated reticle also doesn’t affect my astigmatism like red dots do, so no “starburst”. Which is another reason I am switching over to prism optics. The somewhat limited eye relief didn’t seem to be a problem. When I say somewhat, the reticle is still visible at 12” of eye relief, it is just harder to locate because the window size gets smaller. The TSP1 also performed very well for me when I used it in a big local shooting match. Athlon doesn’t state battery life, but the initial AAA battery is still going strong. After all, the AAA batteries are super easy to find, even at a tiny store in the middle of nowhere.

  Athlon Optics did a pretty good job with the Midas TSP1. The MSRP may seem a little high, but street price is right on par for a 1x prism sight. Plus you get multi-colored reticles and it uses that AAA battery. If you are like me and want a good 1x prism sight, check out the Athlon Midas TSP1. It’s a good all around prism to replace that fully battery powered red dot.

Really nice optic. It needs more information,

A representative told me the mount is proprietary. It however does in fact work on Industry standard T1 Micro Style mounts. Fits good in an ADM Mount, RS Regulate for AKs, or even a low mount for Shotguns or PCCs like the Scorpion/Stribog.

Athlon if you were open about this tidbit, you'd sell a lot more! It's a prism scope with a similar size to other micro red dots and it takes T1 mounts. Almost perfect for what it is.

Primary Arms SLx 1x Prism

, , , ,

  I was looking around for a prism sight to replace one of my red dots on an AR rifle. I was tired of the flared out dot due to my astigmatism. So when the chance came along to get behind the Primary Arms SLx 1x prism, I was literally a kid in a candy store. The Primary arms SLx worked great as the red dot replacement.

  The SLx 1x prism had all the features I wanted in a true 1 power optic. For one, it was a prism sight. Therefore it has an etched reticle, like most magnified optics. I really like this as a feature, it takes away the burst that red dots have for me, and it gives an actual reticle, even when not illuminated by the battery. I’ll get to the actual reticle later. The SLx’s reticle illumination is red, but green is also an option. Another feature that I wanted was good eye relief. Since it’s not a red dot style optic, eye relief is important. The SLx has a stated 2-6” of eye relief. But it really feels like more. I can get right up on the optic or back off even more than the 6”s and still get a good sight picture, so much so that it feels very much like looking through a red dot optic.

  Primary Arms gave the SLx 1x prism their ACSS Cyclops gen II reticle. The ACSS (Advanced Combined Sighting System) Cyclops is a horseshoe style etched reticle with a chevron, think triangle, in the middle. The round horseshoe part gives extremely fast target acquisition, especially for close up targets. It is also about the size of a 00 buck pattern at 25 yds. The chevron then takes over for precise aiming. You can also use the chevron like you would a red dot, if up close. The top point of the chevron is where you would zero your rifle. This point is also where you get pretty precise aiming by just putting the point on the target. The zero depends on what barrel length and caliber you are using (see picture). With a 16” 5.56 barrel, it would be 100 yds. The inner point of the chevron is now a bullet drop compensator. So with the same 16” barrel, this would be for 300 yds. Then the bottom part of the chevron would be 400 yds. The BDC is just a close estimation, since it also depends on ammunition type and the height at which the SLx is mounted. There is also range estimation built into the SLx. It uses a 5’10” tall or 18” wide object for range estimation. When sighting in, the SLx has 1 MOA clicks for both the windage and elevation adjustments. The clicks are very positive. The adjusting dial is recessed into the SLx’s housing so that the adjustments won’t be hit and knocked out of zero. It also makes for a smoother look. Even though the 1 MOA adjustments worked fine, since the SLx has the precise chevron aiming point, I would have liked to see more accurate adjustments, maybe more like ¼ MOA, or even ½ MOA.  

  Illumination comes from a CR2032 battery that rides inside the brightness knob. The SLx has 13 brightness settings. The highest are “daylight bright”, and the lowest 3 are for night vision. Yes, the “daylight bright” does illuminate the reticle in bright sunlight. It’s not quite as bright as a quality red dot, but you can still see that it is a brighter red. My biggest complaint about the SLx is it’s mushy and hard to turn brightness knob. The click between levels just suck, plus it’s hard to get the dial to turn to them. If it had better “clicks” I wouldn’t complain as much about the stiffness. But, on the other side of that is the awesome “Autolive” function. This is a motion activated auto on function. After a certain time of no motion, the illumination will turn off. Then, when it gets moved, even just a little, the reticle turns back on to the last brightness setting it was on. The Autolive works fantastic, see this as to how well it works: YouTube Video. Because of the Autolive function, battery life is greatly extended. In fact, Primary Arms states the battery life to be 29,000 hours on the medium setting! Remember, if the battery dies, you still get the advantage of having an etched reticle, it’s just no longer illuminated. 

  The SLx gives a very clear window in which to look through. I found this prism sight to be way clearer than I expected from a $250 optic. It has a pretty good Field of View at 76.5 ft @ 100yds. It has a very forgiving eyebox and even has a diopter to focus in the reticle for your eyes. Even when looking through the SLx at odd angles, I was still able to get a good sight picture. 

  The Primary Arms SLx 1x prism comes with a variety of mounting options, all of which are included in the package. The SLx comes with 4 spacers and a picatinny rail mounting base. 3 of these spacers are cantilevered, the other 1 is straight. This lets the SLx mount right above the rail, with no spacers, or up super high off the rail with the straight spacer plus the high cantilever one, and anything in between (see picture). Of course all mounting screws and wrenches are included to swap the heights around. Oddly enough, the SLx can also be mounted to a carry handle of an AR. All these height options let you tune the height, so if you are using a magnifier or back up iron sights, you can get it just how you like it. Yes, the SLx prism will work with those too.

This is not on full brightness, more like around setting 7 of 13, in full sun

  Primary Arms did a fantastic job with the SLx 1x prism. It does almost everything I wanted it to do, okay, it does everything I need it to do. The clarity is great, it’s bright, has auto on/off, good battery life, and even works without the illumination. The 1x appears to be a true 1 power to me. Everything close up and far away is clear and size appropriate. Shooting with both eyes open is just like shooting with a non magnified red dot, plus no starburst. Having the ability to mount the SLx at various heights is also nice. I like this optic so much that I might even mount it on my “go to” rifle. Go check out the SLx 1x prism at Primary Arms.

MAY BE MY NEW FAVORITE OPTIC!

Put this on an AR15 in 5.56 and the performance was fantastic. The included mounting system is excellent, the reticle is outstanding and the field of view for such a small optic is surprising. I like the etched reticle and the brightness settings are perfect for all lighting conditions. Up until now my favorite optic was the Trijicon MRO but at half the price red dot is hard to beat. Seems just as if not more so rugged that much more expensive options. The only drawback and it's a small one is the 1 MOA adjustment increments which could make it difficult to really dial it in at range but out to 50 yards on my rifle it was dead on.

Primary Arms GLX 2x prism w/ACSS Gemini 9mm reticle

, , , ,

  When Primary Arms offered to send their new GLx 2x prism sight out for review, I jumped at the chance. I had been looking for something to put on my 16” pistol caliber carbine, and this sounded perfect, especially since it was specifically designed for a 9mm PCC. This prism scope uses Primary Arms’ popular ACSS reticle with daylight bright illumination. The GLx prism is something different, that works quite well.

 The GLx 2x prism has numerous features. All of which make it a great optic. The first is the ACSS Gemini reticle. This reticle was designed for the 9mm Luger cartridge in a pistol caliber carbine. The simple explanation of the ACSS reticle is that it’s an upside down horseshoe shaped circle with a center triangle aiming point. It also has ballistic drop compensation (BDC) built into the reticle. Below the reticle is a target ranging ladder. The horseshoe also acts as an 8.6 mph lead when shooting moving targets. I do wish the reticle had some sort of hash marks, on the horseshoe, to keep it lined up with the aiming point, when leading a target. The bullet drops and ranging are best described by Primary Arms’ diagrams. Sighting adjustments are done with capped turrets. Once unscrewed, the caps can be turned over to adjust the windage and elevation in 0.25” MOA increments.

  Primary Arms uses multi coated low dispersion glass in the GLx. This glass gives the optic great clarity. I found that the view through the GLx is super bright and clear. The etched reticle is also very clear and defined. This is probably due to an adjustable diopter for getting the reticle perfectly clear and adjusted to your eyes. Because the GLx is a prism sight, there is eye relief. Primary Arms states the optimal eye relief is 3.7” from the optic. I found that the GLx is very forgiving in the eye relief department. I get a good sight picture with my eye only an inch away and all the way out at around 6 inches of eye relief. The reticle is still very clear and usable at both extremes.

  The GLx’s illuminated reticle has 11 brightness settings. The first 3 can be used with night vision devices. The highest 2 are what is called “daylight bright”, and are bright enough to be used in bright sunlight. Yes, the reticle shines a bright red, even in direct sunlight. However only the horseshoe and aiming triangle are illuminated. The BDC and ranging portions are not. Because of the nature of prism sights, if you have an astigmatism, the illumination will not “starburst” out like a normal red dot will. My only complaint about the illumination is the adjustment dial, the detent clicks are mushy feeling and not crisp at all.

  Battery life can be a concern for some people. Primary Arms gave the GLx what they call “AUTOLIVE” motion sensing technology. This greatly improves battery life from the single CR2032 battery. How you might ask? Well, it automatically shuts off the illumination after 3 minutes of inactivity and turns it back on when motion is detected. They say this gives a battery life of approximately 20,000 hours on the medium settings. The Autolive works extremely well. Everytime I pick up the rifle, the reticle is on. I tested the off function also, and it does turn the reticle off after around 3 minutes of sitting idle on a bench. I have left the reticle turned on for most of its life here, without any problems. Plus, if the battery does go dead, the GLx still has an etched reticle for you to use.

  Some people might wonder why the GLx prism comes in a fixed 2 power. The fixed 2x gives a little better target identification. But it also still gives the shooter an option to shoot with both eyes open. It barely took me any time to get used to it. I found the GLx to be just as quick, transitioning from target to target, as my previously mounted red dot. Having twice the magnification, plus the ACSS reticle, made the longer shots easier also. I was consistently hitting a 12” steel plate at 200 yards using the BDC portion of the reticle. For close targets, I just put the triangle on the target and pressed the trigger. If you want more precision, on close targets, one can use the top point of the triangle. 

  The GLx sight comes with all the mounting hardware needed. For one, it comes with three spacers to get the correct optic height for your carbine. It also uses standard mini ACOG bases, so if you don’t like the supplied mounting options, you can choose someone else's mount. Primary Arms also supplies various screws for the mounting of the spacers and for other styles of mounts. A little tube of Vibra-Tite (thread locker), wrenches, and a cleaning cloth are also included.

  I wouldn’t consider the GLx 2x prism to be on the large size for this type of optic. It leans toward the smaller side, but still larger than most of the red dots of today. The GLx is not a red dot, but I am using them as a comparison for size. Total length comes in at 5.3 inches. The total width is 2.3” inches because of the battery and brightness adjustment. Otherwise the tube is about 1.5 inches in diameter. Total height without any spacers is roughly 2 inches. It does weigh 11 ounces, so about twice what their 1x micro prism weighs, but the same as some other 1x prism sights. I thought the size and weight were about right for all the features the GLx has to offer.

  The Primary Arms GLx 2x prism works very well for its intended purpose on a 9mm PCC. I really like the AUTOLIVE feature. The 2x is a good all around magnification for a 9mm rifle. The ACSS reticle is clear, easy to use, and packed with features. I would definitely check out Primary Arms’ optic line. They did a very good job on the GLx with the Gemini reticle.

SHOCKINGLY AMAZING OPTIC

For a CZ Scorpion, this optic is perfect. As a member of the old eyes club, if its not a Prism sight, I can't see as clear as I need to, so red dots are off the table. I have tried many red dots, and they have a snowflake image when I look through them and they are 1X, so a 2X is much better for my needs. This optic is extremely clear. This is not quite a Trijicon, but at 1/3rd the price and with the ACSS Gemini 9mm Reticle, this is a fantastic optic, especially for PCC's. When they come out with a 3X GLX, I will buy it too.
