The LBE Unlimited Pistol Buffer Tube Kit in black (brand part no. PBUFKTBLK) bundles every part needed to finish the back end of an AR-platform pistol build into a single order. The kit includes the pistol buffer tube itself, a castle nut, a receiver end plate, a carbine-length recoil spring, and a standard carbine-length recoil buffer, so builders are not stuck sourcing five separate parts from five different listings. LBE Unlimited manufactures every component in the USA, keeping quality consistent across the kit. It is a straightforward way to finish an AR-pistol lower without guessing at compatibility between mismatched parts.
