The Armaspec SMB Gen 3 Buffer Kit (brand part no. ARM268-C) comes with everything needed to complete a rifle build’s buffer system, centered on Armaspec’s SMB — the Sound Mitigation Buffer. Armaspec designed the SMB as a superior upgrade over the OEM mil-spec buffer, spring, and weights, quieting the spring twang shooters hear through a cheek weld while smoothing the cycle. Among AR buffer system upgrades, the SMB kit is a complete-assembly answer rather than a single-part swap.
