Expo Arms
Overview
The Expo Arms H2 AR-15 Carbine Buffer is designed specifically for carbine-length gas systems, providing the necessary weight to ensure reliable cycling and performance in your build. Its design helps to absorb recoil and reduce wear on your rifle's components, making it an essential part of a well-functioning AR-15 setup. This buffer commonly appears in builds featuring a mid-length gas system and chambered in 5.56 NATO, optimizing performance for those configurations.
