Magpul PRS Stock

Magpul PRS Stock

GOD BLESS THE MODERN SPORTING RIFLE. As many have said, the AR-15 (and AR-10) platform are like Legos for adults. Customization is the greatest selling point of either platform, as you can modify the rifle's furniture to optimize it's ergonomics and aesthetics for whatever role you desire.
If a more modern, long range accurate type of rifle is what you are after, the buttstock isn't typically the first part that gets attention. Logically a longer, thicker barrel is installed first to facilitate better accuracy. That component adds weight to the front of the rifle, tipping the balance forward and making some buttstocks, collapsable or otherwise, impractical. A heavier stock with the ability to custom fit the shooter and optic is recommended. The ability to adjust for length of pull (LOP) and cheek weld height is a huge upgrade for any rifle stock, especially the A2 style fixed buttstock that's been standard since the origins of the platform.

Magpul PRS Stock

Enter the Magpul Precision Rifle Stock (PRS). While it's not the newest stock on the block (debuted in 2005) the PRS still holds its own and is often the gold standard for how a precision rifle stock should look, feel, and perform. Not only is it compatible with the AR-15 in .223/5.56 and the AR-10 in 7.62x51, but also the HK91/G3 and the FAL have received adapted PRS2 models from Magpul. The PRS has graced the covers of magazines, DVD covers, and boutique black rifle catalogs since its inception, and for good reason. Its a damn sexy design that accomplishes the task of balancing and complimenting a precision rifle, while giving the shooter an anchor of consistency before the trigger is pulled.

Magpul PRS Stock

Today the PRS has resurged again on the covers of popular magazines and gun shop shelves as modern chassis for bolt action rifles are becoming more prevalent, with compatibility with AR-15 buffer tubes and aftermarket stocks. The features that make the PRS stand out as an optimal stock for benchrest AR-15 shooters carry over to a bolt action platform very well, as it still afford the shooter ultimate ergonomics for their head and torso as well as balancing out their front heavy rifles.

Magpul PRS Stock

The PRS is a direct replacement for an A1 or A2 fixed stock on an AR15/M16 with a rifle-length receiver extension tube. The cheek riser is designed to clear the charging handle of AR15/M16 rifles only. For AR10/SR25 pattern rifles, you will need to order the correct PRS stock.
For a precision rifle with a heavy front end, whether its an AR15 with a 24" bull barrel or even a bolt action rifle in a chassis with an equally heavy barrel and brake, the PRS is and ideal stock. Perfectly suited for balancing the weight, providing customized ergonomics for consistency on the firing line, and having robust mechanics that will provide a lifetime of service.

What others are saying?:

"Only thing I would caution people of is the cheek piece will not benefit you if you shoot nose-to-charging-handle. This is needed to allow for proper function of the charging handle. I am 5'10", medium built and have the butt extended most of the way out for a comfortable prone shooting position with my cheek on the front edge of the cheekpiece." Brownells Customer Review

"In one sentence.  - perfect cheek weld. But for those that would like more detail: If you are looking for a drop in, precision-adjustable butt stock for  AR rifles with A1/A2 fixed stocks I'd not hesitate to recommend this one based on my experience with one I purchased 2 years ago.  There are a lot of different accessories for the AR15 series firearms, and though I wasn't wanting to put together "frankengun", I did want a stock that had a means of adjusting the length of stuck as well as comb height for the perfect alignment of my site choice, which was an EOTech.

Every shooter is physically built differently, male or female.  I'm as tall as many guys, but my arm length doesn't compare and my shoulders show my more delicate bone structure.  So adding something like the Magpul PRS is well worth it if you have other than normal length arms, neck or sighting requirements.  Compared to the A2 stock, the PRS can shorten LOP (length of pull) by .25" or extend it by .75" as well as provide three-quarters of an inch of comb height adjustment.(the height so that when you plant your cheek onto the stock, your eye is lined up just where it needs to be to line up with the reticle.)"

PWS FSC556 Compensator

PWS3When I decided to dive into the AR-15 world, I needed to choose and a muzzle device. Since I was going to be using a 14.5inch barrel, I needed a long enough muzzle device to reach the 16 inch overall barrel length, so I wouldn’t have to SBR the rifle. I was looking for a device that was not only a flash hider but also a compensator.  This limited my selection, however, the choice was easy once I came across the PWS FSC556 Compensator. Once I installed it on my rifle, I was reaffirmed in my selection. Not only was it good at hiding the flash, but the compensation was fabulous. Shooting the rifle with the FSC556 was comparable to shooting a 22 long rifle. The compensation keeps the rifle shooting nice and flat, which aided in getting back on target quicker and moving from target to target. I have shot other compensators that seem to drive the barrel down more than necessary. And the FSC556 stayed nice and level. This muzzle device is definitely not the quietest out there, however, it is also not the loudest I have heard. Along with the increased noise (which I really didn’t notice but was told by my friends shooting with me) was the increased muzzle blast to that is directed to the sides. My friends shooting next to me kindly (or not so kindly) let me know about this. All I had to say though was “look at my groups” and they wanted to shoot it.


Since purchasing the FSC556 I have also put the FSC30 on my AR-10 and it does just as good of a job on the heavy hitting 308.

Hornady Lock-N-Load O.A.L. Gauge & Bullet Comparator Kit Review

Hornady LNL OAL Gauge & Bullet Comparator One of the most addicting aspects of reloading ammunition is the specialized tools that are so readily available today that improve the process and help squeeze every bit of accuracy out of your firearms. Two products that I recently invested in are the Hornady Lock-N-Load OAL Gauge & Bullet Comparator Kit (you'll also need to pickup a modified case - usually will be displayed right next to these products on the shelf. These three tools used together help determine how a specific bullet best fits into your chamber by its Ogive (pronounced o-jive). The Ogive of the bullet is the plane that lies between the straight wall and the rounding taper. Each bullet differs in greatly in base to tip dimensions, between each manufacturers unique "style," the bullet type, and the grain/size. In fact it's common for variations of up to .025" to exist from one bullet to the next. However the Ogive is what engages with the barrel's rifling lands, and gives the reloader a more consistent standard of measurement.

Basing your seated bullets off the O.A.L. (Overall Length, from case head to bullet tip) is standard stuff, and while it will help keep you within SAAMI specs and inline with factory ammo, you could be missing out greatly in terms of accuracy and performance. Measuring off the Ogive will give you a more customized relationship between your desired bullet and your specific rifle's chamber. The best metaphor I can think of is imagine if you could customize the tread on your car's tires so specifically to your vehicle and the road surface so that it gave you an extra 3-5 miles per gallon. While seating depth won't effect velocity, a bullet seated to a precise length relative to YOUR rifle's barrel will noticeably improve performance.

*Note: you will also need to keep in mind your magazine length limitations.  If the O.A.L. of your cartridge after fine tuning using this process is greater than the wall of the box magazine or bottom metal, then you will have to single load each round into the rifle.

The O.A.L length gauge and modified case let you set up a bullet in a case with maximum overall length between your closed boltface and the barrel's lands. You may be asking, how the heck do I measure the length to the Ogive instead of the bullet tip?  Well, thats where the Bullet Comparator comes in.  It is an adapter that easily attaches to the blade of your caliper. It comes with interchangeable inserts for bullet diameters including .224" (5.56mm), .243" (6mm), .257", .277", .284" (7mm), .308" (7.62&8mm). When installed on a rezeroed caliper, it lets you measure a cartridge from casehead to bullet Ogive. That's the shorthand version. For those who aren't passed out on their keyboards or off surfing YouTube, I'll explain the whole process a bit more thoroughly. If you grasp the concept, you can skip to my review key points.

Hornady LNL OAL Gauge & Bullet Comparator

First you take your modified case and thread it onto the O.A.L gauge, then lightly push your desired bullet into the case to the point where it's seated deeper than normally. For example, I'll thread on a .308 win modified case and then insert a Sierra 168gr MatchKing bullet. Just don't push it too far were it falls into the case or else you'll have to push it out or fish it out. Next, remove the bolt from your rifle (or use the curved gauge if your rifle's bolt does not come off)  insert the O.A.L. gauge through the action (slowly) and into the chamber. You don't want to jam it with too much force that you unknowingly alter the modified case. When its gently snug, you then push the plastic inner rod of the gauge forward, which will push the bullet forward in the case and if you're sensitive enough you will feel the bullet engage the lands of your barrel's rifling. You can then tighten the thumb knob and lock that inner rod, and pull the gauge out of the action.  Again, if you use too much pressure you may lodge the bullet in the lands and will not come out with the gauge, and you'l have to start over.

So now you have your gauge with the modified case and bullet still in position, and then get out your caliper with the comparator and proper insert installed. You will have to rezero the caliper closed on the comparator first. With both tools in each hand, insert the bullet tip into the comparator, and adjust the caliper to measure off the case head as usual. Now instead of a reading for overall cartridge length from casehead to tip, you will have the exact distance between casehead and your bullets Ogive (exactly 0.00" using my .308 win and the SMK 168gr) Now's were the fine tuning comes it. That dimension tells me when my bolt in closed, the shallowest I can seat that specific bullet where it will be into the lands of the rifling. You will want to back off of this some, between 0.015" and 0.02" typically to start but every rifle/bullet combo will have a sweet spot. It's up to you to determine whether your rifle's barrel prefers that specific bullet closer or farther from the lands.

While this may seem like splitting hairs to some, the accuracy difference can be up to 0.5-1 MOA.  At longer ranges, using the Hornady Lock-N-Load OAL Gauge & Bullet Comparator Kit can be the difference between a fantastic group in one singular hole, or just a decent 1 MOA group. Based on my results, I find I will almost never buy a box of factory ammunition, as long as I have the brass and components I am able to make cheaper and more accurate rounds.

Firearms Insider Reviews - 8 Key Points

Claim to Fame: Measuring cartridge lengths across bullet tips is not a reliable or repeatable method for measuring your reloaded rounds. The O.A.L Gauge and Bullet Comparator solve that problem by measuring rounds from a reliable surface on the bullet, the ogive, to provide consistent, precise measurements of your rounds and improved accuracy.

Target Market: Reloaders both Novice and Experienced

FNBs (Features & Benefits of this product):

What other aesthetic options or finishes are available?: The O.A.L Gauge comes in either straight or curved orientation to best work with your rifle's action.

What others are saying?: “I decided to order this comparator when I purchased my Remington 700 SPS Tactical (.308). When I bought this rifle, I wanted to take my reloading a step further and dive into the world of precision hand loads. Up to this point, I was reloading rounds mostly for target practice and a few for hunting every year. So the reloading gear I own was sufficient enough to get the job done, but not for higher quality hand loads. But as I began realizing how challenging precision hand loading can be, I knew that I would have to reach out and get some reloading equipment that could help me get the job done.

Due to the fact that I had no experience with the tools needed for this type of work, I simply called into Sinclair International and spoke with one of their many highly experienced reloading techs. He couldn't have been more helpful in explaining about important tools, explaining how and why they worked. As you may have guessed, he suggested this comparator as an essential tool for the entire process." Brownells Review Price Point:

Remington 700 AAC-SD + Bell & Carlson Medalist M40 Stock





When it comes to bolt action rifles, the Remington 700 platform is almost ubiquitous.  Big Green has created over a dozen varieties and flavors of bolt guns based off the platform because of its success and time-tested reliability.  Police and Military have used the 700 for quite some time, and it's no stranger in the field for both big and small game.  Variety is the spice of life, and Remington has something to offer most consumers no matter the niche they are after.

The 700 SPS Tactical is designed as a compact tactical rifle with a shortened 20 inch varmint (heavy profile) barrel, BDL floorplate, and a Hogue overmolded stock that's usable in any weather condition and makes grip & recoil both manageable.  It is chambered in both .308 Win and .223 Rem. The Hogue stock has a flatter type forend and a low, straight comb. It's really more of an entry-level tactical bolt action rifle meant to be accessible to a greater range of the market.  The AAC-SD variant is the same rifle, but with a "ghillie" Hogue stock that's green with flecks of color and swirls.  It has the letters AAC stamped on the receiver, and is only available in .308 Win although I've seen some in 300 Blackout floating around.

I snatched up the rifle because of the hype and it already having a threaded barrel.  On the shelf, initial impressions are pretty high.  It shoots fairly well, many owners have claimed MOA or sub-MOA out of the box.  Mine wasn't exactly as consistent, and has lead me down the path of reading, learning, and smacking myself in the forehead a couple times.  The first thing that needs replacing is the stock.  I would have paid an extra $200-250 if it had come with an HS precision or B&C stock, but perhaps it was thought that shooters who want to invest in greater accuracy would take the trouble to do so already, and so they slapped on the Hogue stock as a lowest price point option.  The hogue stock has flex to it, sure it has aluminum pillars but the forend WILL touch the barrel when using a bipod or any support.  That's a bad thing if you want your bullet holes anywhere close to each other.  I opened up the last 2 inches of the stock with a dremel to compensate for this which had to help some, but ultimately if you are after a rigid stock with solid contact with your rifle and a free floated barrel, you have to ante up and upgrade.  The difference could be 0.5"-1" tighter groups at 100 yards, which may or may not be a concern for your own level of confidence and satisfaction.



I decided to pick up a Bell & Carlson Medalist/Tactical "M40" type stock.  There's alot of options out there, and how I decided really was price, and how good did this same rifle look in each stock during a google images surf session.  The time tested military style M40 riflestock was introduced in the 1970’s, replacing the wood stocks on standard issue U.S. Military sniper rifles. Even though the U.S. military has moved into other configurations, this M40 silhouette's popularity continues to increase to this day as the chassis is hard to improve upon.  B&C's M40 was found at just under $250 through Redhawk Rifles, and it was only 2.5lbs which addressed my total weight concern.  I plan on using this as a hunting rifle as well as shooting from the bench so a compromise in weight was needed.


Now if I was a really thorough reviewer, I would have photographed groups with the factory stock, groups before bedding, and groups after bedding.  But I didn't get around to it, so you'll have to take my word that the above photo with a 3 shot group under 1 inch at 100 yards is the best I've shot with this gun, and that was with cheap 150gr factory ammo.  I'm confident now that working up some reloads in the 168-175 pill range will produce some very good results.

The Truth About Guns Review

"Great rifle for what I paid, makes an excellent budget precision starter kit. I did change out the stock, because the Hogue overmold stock, although attractive, was way too flexible. On a bipod I can actually watch the stock contact the barrel, negating the free float. It would be 5 stars if not for the stock, which I consider to be a conceptual flaw. This is meant to be a tactical rifle, with the ability to make multiple accurate shots. This is not possible form a bipod with the included stock. " Buds Guns Review

B&C M40 Stock: "The B&C Medalist stocks (of which we are discussing) are a hand laid Kevlar and composite shell with fiber reinforced foam over an aluminum inner chassis. The aluminum skeleton runs "grip to tip". I have several of these. I can tell you they will stand up to more than most on here will ever put their rifles through. I will say that in my opinion the B&C Medalist stocks are higher quality than H&S Precision stocks."

- Factory Hogue stock is the weakest link, a must-replace for any serious shooter. - Remington's 700 bolt handles aren't as robust as they were in the past, can be broken if dropped or prying bolt open on stuck casing. (Had mine tapped and secured with a screw for extra support)

B&C M40 Stock: + Absolute drop-in fit with no modifications needed (on this particular rifle, your results may vary) hinged floorplate operates correctly. + Improves groups greatly from factory Hogue stock + Precise CNC-machined aluminum bedding block ensures a perfect metal-to-metal fit along receiver, aligns the barreled action, stiffen the forend, and eliminate the need for conventional bedding methods (Although glass bedding will still help create a perfect, gapless bed.) + Freefloats the barrel + Weight kept down compared to other model stocks 3lbs + over +  Stock comes with a lifetime factory warranty on materials and workmanship.

- Inside factory inletting was a little rough on this particular stock, but got filled in during glass bedding process anyway. - Outdated company website (call me, B&C!)


Score: 6.5 OK65

R700 AAC-SD:  Reasoning - for the MSRP amount and AAC's name attached I expected more innovation or at least a better all around rifle instead of an SPS w/ threaded barrel and different color stock. It's still a good rifle, but a tackdriver or tactical rifle out of the box it is not. Cost saving corners for Remington are pretty obvious. For $600-$800, better performers are available.
