Armaspec SMB-C Sound Mitigation Buffer Gen 3 Captured Silver AR-15

The Armaspec SMB-C is a Gen 3 Sound Mitigation Buffer built as a single-stage drop-in replacement for your standard AR-15 buffer and spring. Its captured design locks the buffer inside the buffer tube so it cannot travel rearward, making it a smart match for adjustable stocks that clamp over the rear of the tube.

Machined with a silver finish and made in the USA, this Carbine-weight buffer comes in at 4.41 oz, delivering the familiar carbine recoil impulse while the captured spring system helps dampen vibration and noise for a noticeably smoother shooting feel. The Gen 3 design refines the internal geometry over previous generations for greater reliability and consistent cycling.

Installation is straightforward - drop it into your existing carbine buffer tube in place of the stock buffer and spring, no modifications required. Backed by Armaspec's lifetime warranty.
