A RRA-10 buffer will allow you to use any AR15 collapsing stock (Magpul/LMT/VLTOR/Ace/etc) on your Rock River Arms .308 AR. Standard carbine length stocks cannot be used on these rifles with regular carbine buffers. This is strictly a 'Drop-In' part, no gunsmithing or modifications are required.

This product is specifically recommended by Magpul for use with their carbine stocks on RRA.308s. (Call them!) RRA-10 buffers also work great with any other stock using a standard 7" carbine buffer tube.

RRA-10 buffers are shorter and heavier than standard carbine buffers (and other .308 carbine buffer). Constructed of 303 Stainless Steel with a sliding Tungsten anti-bounce counterweight. Heavy buffers reduce felt recoil for the shooter, and minimize wear and tear on the gun. Some users have reported that the RRA-10 buffer significantly increased the reliability of their firearms.

Note: Not compatible with AR-15s. This buffer is designed specifically for use in RRA .308 ARs with 7" receiver extensions (buffer tubes). If you have an RRA extended length buffer tube (8") I recommend an XH Carbine buffer.

Note: We cannot guarantee proper function with subsonic ammo. There are significant differences in specifications among the various brands of ammo and firearms manufacturers. Some guns will run great with almost any ammo, other guns may not function reliably with any subsonics. This is all beyond our control.
