Armaspec SMB Buffer Kit H3 Gen 3 – AR-15 Recoil System

The Armaspec SMB Buffer Kit H3 Gen 3 reduces felt recoil and bolt carrier bounce in AR-15 platforms through a captured spring design with internal noise dampening. The H3 weight configuration (5.4 oz) helps smooth out cycling in carbine-length gas systems, particularly with suppressed or over-gassed rifles, while the Gen 3 design eliminates buffer rattle and reduces overall noise signature.

Built with a captured spring system that requires no modifications to install, this buffer kit drops into any mil-spec AR-15 carbine receiver extension. The sealed construction keeps lubricant and debris out of the spring assembly. Compatible with standard carbine buffer tubes and retaining pins. The H3 weight is heavier than standard carbine buffers, making it well-suited for suppressed shooting or firearms with adjustable gas blocks where reduced bolt speed is beneficial.
