LBE Unlimited ARLPLT Receiver End Plate Steel Black Phosphate AR-15

The LBE Unlimited ARLPLT Receiver End Plate is a drop-in lower-receiver component for the AR-15 that seats the receiver extension (buffer tube) and provides the flat rear surface the castle nut is torqued and staked against. Built from 4140 steel and finished in a corrosion-resistant manganese phosphate coating, it is a direct replacement for a worn or lost factory plate on any standard AR-15 lower running a mil-spec buffer tube and castle nut.

The end plate is designed to give the receiver extension proper alignment under repeated assembly cycles and to take castle-nut staking without twisting out of register. The black phosphate finish matches other phosphate-coated components in an AR build, keeping the rear of the lower visually consistent and protected from surface corrosion. Made in the USA and ready to drop in during your next build, repair, or routine maintenance interval.
