The Armaspec Gen3 Sound Mitigation Buffer (SMB) Mil-Spec Buffer Tube Kit is a complete, ready-to-install assembly for AR-15 carbine builds. It includes a Gen3 SMB buffer, a mil-spec 7075-T6 aluminum 6-position carbine buffer tube, end plate, and castle nut. Choose SMB-C, SMB-H, SMB-H2, or SMB-H3. The SMB is a single-stage drop-in replacement that keeps the buffer spring from rubbing against the inner wall of the buffer tube while reducing felt recoil and mechanical noise.
