LBE Unlimited H1BUFKT Buffer Tube Kit H1 6-Position Mil-Spec Black AR-15

The LBE Unlimited H1BUFKT Buffer Tube Kit is a complete mil-spec AR-15 lower-receiver extension package, assembled to give a builder everything required to finish a collapsible-stock carbine build in one drop-in box.

At the heart of the kit is a six-position, mil-spec diameter buffer tube finished in matte black, paired with an H1 heavy recoil buffer and a carbine-length recoil spring - the same buffer and spring combination found on most factory carbine builds and well suited to general-purpose use on standard AR-15 rifles. Rounding out the package are a receiver end plate and a castle nut so the extension tube can be properly secured and staked to the lower receiver right out of the box.

The complete kit ships ready to install in matte black and includes one six-position mil-spec buffer tube, one H1 heavy buffer, one carbine-length recoil spring, one receiver end plate, and one castle nut.
