Ambidextrous Controls

The ambidextrous bolt release on the Sharps Bros receiver lets you operate the bolt catch from either side without switching hands or grip position. This is especially valuable for left handed shooters or those who train from multiple positions. The threaded bolt catch pin is included and ready to install.

Complete Lower Parts Kit

This kit includes everything needed to complete the lower receiver assembly. The mil-spec lower parts kit handles the trigger group, hammer, disconnector, selector, magazine catch, and bolt catch components. You get a standard mil-spec pistol grip and all the springs and pins required for operation. No additional parts are needed for the lower receiver itself.

Buffer System and Brace

The mil-spec carbine buffer tube provides 6 positions of adjustment for cheek weld and length of pull. The standard carbine buffer and recoil spring are included. The Magpul BTR brace mounts directly to the buffer tube and features a minimalist fixed profile design with integrated sling attachment points for tactical versatility. The brace is sized for AR-15 pistol platforms and pairs seamlessly with the mil-spec tube.
