Lower Receiver

The receiver is a Sharps Bros. Gen 2 Livewire, forged and CNC machined from a custom 7075-T6 aluminum forging and finished in black anodizing. It's built as a multi-caliber, semi-automatic-only receiver featuring an ambidextrous bolt release, with a threaded bolt catch pin included for installation. The receiver weighs 8.70 ounces and measures 2.30 by 4.35 by 8.75 inches.

Lower Parts Kit and Buffer System

A complete Mil-Spec AR-15 Lower Parts Kit covers the fire-control group and the rest of the internals needed to complete the lower, and a pistol grip is included as part of the kit. Behind it sits a Mil-Spec heavy-duty six-position carbine buffer tube, holding a standard carbine buffer weighing 3 ounces and a standard USA-made recoil spring. A US Tactical AR-15/M16 Mil-Spec receiver end plate and AR-15 carbine castle nut secure the buffer tube assembly to the receiver.

Stock

Capping off the build is a Davidson Defense AR-15/M16 carbine Mil-Spec buttstock, built in an M4 rifle stock style from 6061-T6 aluminum and finished in black. It's a 6-position adjustable design built for a Mil-Spec buffer tube, matching the buffer tube included with this kit, and includes a sling loop mount for attaching a sling.
