Rock River Arms
Overview
The Rock River Arms Carbine Buffer is designed specifically for AR-15 platforms, featuring a carbine weight that optimizes cycling for standard carbine-length gas systems. This buffer helps to ensure reliable operation by managing the rearward motion of the bolt carrier group, allowing for smooth cycling during firing. It's commonly found in builds that prioritize a balanced setup for both performance and recoil management.
