BCM mil-spec carbine stock hardware kit comes complete with the buffer tube, spring, castle nut, end plate, and buffer. Profile is right for a duty build. Locks at each position positively. BCM quality at a reasonable price.
comes with the tube, castle nut, end plate, buffer and spring as a kit. quality is BCM as expected. only oddity is the QD socket on the end plate sits at a slightly awkward angle for a 1 point sling from my carrier, paired with a different end plate to fix
