Sharps Bros Gen 2 Livewire Receiver

The Sharps Bros Gen 2 Livewire is built from a custom 7075-T6 aluminum forging. This material choice means the receiver starts tougher than standard 6061 aluminum before CNC machining adds final precision. The ambidextrous bolt release is the standout feature here, letting you charge the bolt and clear malfunctions without switching your grip. The receiver dimensions of 2.30" x 4.35" x 8.75" keep it compact while the threaded bolt catch pin stays secure.

Adaptive Tactical EX Performance Stock

The Adaptive Tactical EX Performance stock is made from glass filled polymer and adjusts across six positions on the carbine buffer tube. This means you can shorten or lengthen the stock to match your body geometry, shooting position, or gear setup. The QD sling mount and sling loop give you flexibility for how you carry the rifle. The stock weighs just 0.6 lbs., so it won't add bulk to your build.

Buffer System and Lower Parts Kit

This kit includes a mil-spec carbine buffer tube paired with a standard 3 oz. carbine buffer and USA-made recoil spring. The complete mil-spec lower parts kit handles all internal fire control components, so you get a trigger, hammer, disconnector, selector, magazine catch, and bolt catch. The US Tactical receiver end plate and carbine castle nut complete the buffer system assembly. Everything is mil-spec compatible and designed to work together without modification.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
