Most AR-15 noise reduction methods focus on muzzle, but the Armaspec® Gen2 Sound Mitigation BufferTM takes an entirely new approach by dealing with the clacking and scraping on the OTHER end of the rifle. Designed as a single-stage drop-in replacement for your AR-15's standard buffer and spring, the Gen2 SMB keeps the buffer spring from rubbing against the inner wall of the buffer tube—preventing a great deal of noise in the process.
Spring weight is adjustable: the main spring can be trimmed at 4 ounces per coil to reduce tension, up to a max of 12 coils (3 lbs.). And…it reduces felt recoil too.The Sound Mitigation Buffer is made in America, backed by a lifetime manufacturer's warranty, and available in 5 different configurations to fit everything from standard AR-15 carbines to AR-style pistol-caliber carbines. If you want a smoother, softer-shooting AR-15, look no further.
