Armaspec SMB Buffer Kit H Gen 3 – AR-15/AR-10 Recoil Management System

The Armaspec SMB Buffer Kit H Gen 3 delivers smoother cycling and reduced felt recoil for AR-15 and AR-10 platforms. This self-contained buffer system eliminates the need for a traditional buffer spring, using captive internal springs to minimize reciprocating mass noise and carrier bounce. Shooters gain faster follow-up shots and improved muzzle control, particularly on rapid strings or unsuppressed rifles where buffer noise is pronounced.

Constructed with aerospace-grade materials, the Gen 3 design features a non-rotating buffer body that prevents spring bind and wear. The H-weight configuration balances gas system performance for mid-length and carbine-length systems, accommodating most standard AR builds. Installation requires no gunsmithing—simply replace your existing buffer and spring with this drop-in kit. Compatible with mil-spec carbine receiver extensions and most aftermarket tubes.
