Armaspec SMB Gen 3 AR-10 Buffer Kit

The Armaspec® SMB™ Gen 3 AR-10 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 AR-10 buffer assembly, one steel end plate, and one steel castle nut. Compatible with most Mil-Spec lower receivers. Backed by a lifetime warranty. Made in USA.
