• 6-position mil-spec buffer tube (carbine length)
• Recoil spring
• Recoil buffer
• Steel receiver end plate

Designed and built by LBE Unlimited, the MILBUFKT threads into any standard AR-15 lower and is ready to accept your choice of mil-spec collapsible stock. It's an ideal upgrade, refresh, or replacement for builders who want every lower-parts component sourced together in one kit.
