Description
The Sharps Bros The Jack is a billet AR-15 lower receiver machined from 7075-T6 aluminum. It features a skull-pattern magwell design machined directly into the billet stock, eliminating the need for additional magwell accessories. The lower is Type III hardcoat anodized for wear resistance.
Tolerances are held to ±0.005″ on critical dimensions. The lower has an integrated trigger guard and is pre-machined for ambidextrous safety selectors. The threaded bolt catch pin hole accepts standard AR-15 parts kits. Upper receiver fitment follows DPMS specifications.
This is a serialized FFL item that requires transfer through a licensed dealer. The lower ships with a standard AR-15 pistol grip screw and detent spring. No other small parts are included.
