LBE Unlimited MILBUFKT-4POS AR-15/M4 Mil-Spec 4-Position Buffer Tube Kit Black

The LBE Unlimited MILBUFKT-4POS is a complete Mil-Spec 4-position buffer tube kit built for the AR-15/M4 platform and finished in black. This all-in-one kit provides every component needed to assemble or service the rear of a mil-spec lower receiver, making it an ideal drop-in replacement or the foundation of a fresh carbine build.

The kit includes a 4-position Mil-Spec diameter buffer tube, standard receiver end plate, castle nut, carbine-length recoil spring, and carbine recoil buffer. The 4-position tube allows the buttstock to be locked at one of four positions for proper length-of-pull adjustment, providing a direct fit for any standard mil-spec carbine stock.

Machined to standard AR-15/M4 buffer tube dimensions, this buffer tube kit is equally at home as a replacement for a worn or damaged unit, a spare on the bench, or the starting point of a new build. LBE Unlimited's straightforward, mil-spec construction delivers the reliable function that carbine builds demand.
