Description
The Armaspec Gen3 Sound Mitigation Buffer (SMB) Mil-Spec Buffer Tube Kit is a complete, ready-to-install assembly for 9mm AR builds. It includes the Gen3 SMB-9 buffer (~6.8 oz equivalent), a mil-spec carbine buffer tube, end plate, and castle nut -everything you need to mount a stock or brace. 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.
