Armaspec SMB Gen 3 6.8oz AR-9 Buffer Kit

The Armaspec® Sound Mitigation Buffer™ SMB™ Gen 3 6.8oz AR-9 Buffer Kit is a single-stage captured drop-in replacement buffer and spring system designed to reduce felt recoil and keep the buffer spring from rubbing against the inner wall of the buffer tube for smooth, quiet operation. This kit includes one aircraft aluminum buffer tube, one 6.8oz buffer, one polymer base guide rod, one spring, one steel end plate, and one steel castle nut. Plus, the spring weight is fully adjustable for truly custom performance, while the patent-pending design significantly reduces felt recoil for a softer shooting experience and faster follow-up shots on target. Backed by a lifetime warranty. Made in USA.
