Armaspec SMB Buffer Kit Gen 3 Features The Armaspec SMB Buffer Kit Gen 3 is centered around the SMB or Sound Mitigation Buffer a buffer engineered to replace the factory mil-spec buffer springs and weights found in most builds. This buffer is designed to dampen noise and smooth out the cycling of the bolt carrier group during firing which can reduce the sharp mechanical sound many standard buffers produce. Weighing 6.8 oz the buffer strikes a balance that keeps reliable cycling on AR-9 pattern firearms while improving overall shooting feel. Because the kit is built specifically for AR-9 platforms it accounts for the different recoil dynamics of a pistol caliber carbine compared to a standard AR-15. The kit includes everything needed for a complete buffer system install in one package including the buffer tube endplate and castle nut alongside the SMB buffer itself totaling four pieces. This all-in-one approach saves builders from sourcing matching components separately and ensures everything is designed to work together as intended. Finished in a Black and Silver color scheme the kit adds a distinct visual element to a completed build. For AR-9 owners looking to upgrade cycling smoothness and reduce noise with a single complete kit the Armaspec SMB Buffer Kit Gen 3 is available for sale at GrabAGun.
