Overview

This silent captured buffer system is designed for AR-15 platforms and equivalents, providing a direct replacement that eliminates spring noise while maintaining reliable cycling. The Armaspec SMB Gen3 H2 features a 4.7 oz equivalent weight for balanced performance across most gas systems and ammunition types. It installs without tools or modifications, retaining full semi-automatic function—one round discharged per trigger actuation. The self-contained design reduces wear on buffer tube threads and eliminates twang from traditional buffer springs. Constructed in the US with a lifetime warranty, it suits builds where reduced operational noise is preferred, whether for training, competition, or general use. Compatible with most aftermarket lower receivers and mil-spec buffer tubes.
