B5 Systems AR-15 Receiver End Plate – Mil-Spec Buffer Tube

The B5 Systems AR-15 Receiver End Plate is a mil-spec replacement component that secures the buffer tube to the lower receiver while providing a sling attachment point. This precision-machined part is a direct upgrade for worn or damaged stock end plates, or for builders assembling a new lower receiver. The integrated sling loop accommodates single-point or two-point sling configurations without requiring a separate QD socket or adapter.

Machined from steel with a durable black oxide finish, this end plate installs between the lower receiver and the castle nut on any mil-spec AR-15 buffer tube. Installation requires a castle nut wrench and armorer's wrench—standard tools for lower receiver assembly. The low-profile design sits flush against the receiver for a clean, snag-free fit.
