Aero Precision APAR501101 X-15 Stripped Lower Receiver Multi Caliber Black

The AERO Gen 2 stripped lower receiver is the perfect base for your custom AR-15 build. Machined to mil-spec dimensions, Aero lowers work with standard AR-15 components and ensure the highest quality with a correct component interface. The Gen 2 has improvements such as nylon tension screws that allow for a tighter fir between the upper and the lower. The Magwell size has also been increased for easier insertion of magazines and a sleeker look. The lower is machined from 7075-T6 forged aluminum and has a black anodized finish.

This lower is made in America, the rear takedown pin detent hole is threaded for a 4-40 set screw, and it is marked "Cal Multi" with a black anodized finish. It weighs 8.35 oz.
