The Magpul PRS Stock is an excellent choice for your AR style rifle if you are planning on using it for precision shooting.  This specific Magpul PRS is oriented for the large-frame AR rifles chambered in .308/7.62x51mm, such as the AR-10 or SR-25.  This stock allows for full travel of the lengthened charging handle.


Precision Shooting

This stock was made for sniper rifles and precision shooters.  There are several features integrated into the design of this stock that make it particularly appealing to that crowd.  For instance, the Magpul Precision Rifle Stock has adjustable length of pull, as well as an adjustable cheek piece height. 


The length of pull can be shortened by 0.25” or lengthened by 0.75”, giving you a total of 1.0” of travel.  This allows you to properly set up your rifle to your style of shooting. The length of pull can be adjusted to by turning the available adjustment knob.  The adjustment knob is machined from aluminum and allows you to change the LOP by 0.026” adjustments.  The adjustment knob has a positive locking detent that gives you 39 clicks worth of travel.  Once your length of pull is set, the detents are strong enough to maintain the selected position, even under heavy recoil.


The make sure that you are perfectly placed behind your rifle stock, the Magpul Black PRS has an integrated adjustable cheek piece.  The cheek piece can be adjusted up and down.  This gives you the ability to ensure that your eye is properly centered behind your optic.  The cheek piece weight has an adjustable range of 0.75”.  The cheek piece is also adjusted via a machined aluminum adjustment turn knob.  The adjustment wheel allows you to make height adjustments to the cheek piece in 0.026” increments.



This version of the Magpul Black PRS Stock was developed specifically for the large-frame AR-style rifles chambered in .308/7.62x51mm and similar calibers.  This stock will also work on the AR-15 rifle.  This stock was specifically altered to allow for full travel of the charging handle in the long action AR-10/SR-25 and similar rifles.  When compared to the Magpul PRS stock made for the AR-15, this stock has a length of pull that is 1.0” longer.


This stock is a direct replacement for and fixed A1/A2 style rifle stock.  This stock will fit onto a rifle length receiver extension tube.  You will also have to use a rifle buffer and rifle length buffer/action spring. 


Please note that this stock is NOT able to be used on the Bushmaster BAR-10 and the Rock River Arms LAR-8.  These rifles have certain features that interfere with the cheek riser that prevent the stock from working properly with those particular rifles.


Convenient Features

The Magpul PRS was made to impress customers.  The stock has a wide range of features that make it a top of the line stock.


For enhanced durability, this stock was designed with a reinforced aluminum butt plate.  This butt plate is strong enough to withstand recoil from a .50BMG rifle and other sever impacts.  The aluminum butt plate is covered by an removable rubber butt pad.  The rubber padding provides enhanced comfort and also helps to grip onto your shoulder when firing.


One of the great features of the Magpul black PRS stock is that it has a picatinny rail section.  The rail section is mounted on the bottom portion of the stock and has a removable cover to offer protection when it is not in use.  This Picatinny rail section allows for the easy installation of a mono-pod.  This can greatly enhance the stability of your rifle, allowing you to get the best possible accuracy out of your rifle.


The Precision Rifle Stock has an integrate sling mount.  The stock comes with a sling loop that will accommodate a 1.25” wide sling.  The sling loop can be mounted on one of any of the four available positions.
