Expo Arms
Overview
The Expo Arms AR-15 Carbine Buffer is designed specifically for AR-15 platforms, featuring a carbine weight that ensures reliable cycling and optimal performance in your build. This buffer is essential for managing the recoil impulse in carbine-length gas systems, particularly with 5.56 NATO calibers, allowing for smoother operation and improved accuracy. You’ll commonly find this buffer in builds that prioritize reliability and function in standard carbine configurations.

swapped in for a stock carbine buffer on a 16 inch carbine gas build, recoil impulse smoothed out and brass ejects at 3 oclock now instead of 1. the red bumper looks sharp once installed in a clear tube
