Description
The LBE Unlimited Mil-Spec Buffer Tube Kit is a complete 4-position buffer tube assembly for AR-15 and M4 platform rifles, designed to pair with a collapsible or fixed stock. The tube is built to mil-spec dimensions for stock compatibility, so a wide range of aftermarket stocks should fit without modification.
The kit is finished in matte black and measures 11 inches overall. It secures to the receiver extension threads with a castle nut and standard end plate, providing a snug connection to the lower receiver. A carbine-length recoil spring and a standard recoil buffer are included to manage bolt carrier group cycling and felt recoil.
The package bundles the buffer tube, castle nut, end plate, recoil spring and recoil buffer as a single kit for completing or replacing the buffer components on an AR-15.
