Magpul PRS Gen3 Precision-Adjustable Stock
The PRS GEN3 is a field precision AR 15 stock for AR15/M16 and AR10/SR25 platforms, featuring tool-less length of pull and cheek piece height adjustment. With solid adjustments for length of pull and cheek piece height via aluminum detent knobs, the Magpul PRS GEN3 (Precision Rifle/Sniper) stock provides a stable interface and is intended for semi-automatic sniper or varmint type rifles. Offering a nearly universal fit, it is optimized for rifle-length receiver extensions but will also mount to many mil-spec carbine and A5-length tubes*. Includes a cant/height-adjustable rubber butt-pad and rotation-limiting QD sling swivel cups as well as M-LOK® slots on the bottom for rear monopod mounting.

Magpul PRS Gen 3 Delivers

This is a sweet stock. Easy to install, adjustments are smooth with positive lands, movable components are rock solid- no rattles, the butt-pad has a nice squish to absorb recoil, and really gives an edge on getting on point fast. It is on the heavier side, but works well with a heavy profile barrel for balance. If not putting this on an AR platform be careful with LOP- it's a big stock, especially if trying to use a cantilevered or existing mount setup.

I bought an AR-308 that came with a regular AR-15 stock. This Magpul stock made shooting that rifle so much better. I was able to set my sight alignment with the scope very easily with the adjustment dial, making for a more enjoyable shooting experience. Easy to install and a quality product.

I bought this Magpul PRS gen 3 stock to put on a heavy barreled rifle. It's heavy, but that balances some of the barrel weight. It adjusts very easily, so the length of pull fits a short guy like me. The comb height also easily adjusts to get my eye at the right level for the scope.

I installed the Magpul prs stock gen 3 on a precision AR10. As expected with any Magpul product, it installed without issue. Adjustability worked great for me. It makes for a rock-solid point of contact (shoulder and cheek). It adjusts quickly and dependably through iron sight and scope ranges. My only "issue" could be price, but you do get what you pay for, so if you're frugal like me, just wait for a sale.

This stock went on a custom AR 10 Aero Precision. The adjustable comb and length of pull are excellent. No felt the recoil, and the weight balances the rifle just right.

The Magpul PRS Gen3 is well worth the price. This AR Stock is well designed and well built. Works with rifle and carbine length tubes by way of the changeable front part of the stock. The additional of the adjustable but plate is a big plus as with the other upgrades over the previous version

After talking to MSP support to determine the fit of the stock on my rifle, I went with the Magpul PRS Gen3 Stock. I Installed it my a Ruger Precision Rifle in about 40 minutes, (that included removing the old stock). The instructions are not specific to the Ruger rifle, but persistence, common sense, and reading the directions made installation easy. A fantastic improvement over the basic stock. Magpul product,i.e., excellent, quality materials and construction, is what you would expect. I had troubles adjusting the original and keeping it adjusted, and those problems are now gone. Great rifle stock. Glad I got it.
