The Aero Precision AR-15 Gen 2 stripped lower receiver (Aero Precision part no. APAR501302C) is the base for a custom AR-15 build, machined from 7075-T6 forged aluminum and finished in Magpul FDE Cerakote. The Gen 2 design adds a nylon-tipped upper tension screw in the grip tang, which lets you tune the fit between the upper and lower receivers for a tight, rattle-free build. An increased magwell flare makes magazine insertion easier and gives the lower a sleeker look. It is machined to mil-spec dimensions, so standard AR-15 components and magazines work with it.
