A complete AR-10 (7.62 NATO / .308 Win) six-position carbine buffer-tube kit — precision-machined from aircraft-grade aluminum and finished in matte-black Type III Class II hard-anodized coating. Every piece needed to close out the back half of an AR-10 lower receiver ships in this kit.
Kit includes:
Fitment: AR-10-pattern lower receivers only — do NOT install on an AR-15 lower. The AR-10 buffer weight and spring are longer than AR-15 carbine components and will not cycle in an AR-15. Fits mil-spec AR-10 carbine stocks. Zero-gap on install when the castle nut is properly staked. Requires an AR-15/AR-10 armorer's wrench for correct torque and staking of the castle nut.
