The Aero AR-15 Lower, Gen 2 is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, these lowers work with standard AR15 components and ensure the highest quality with a correct component interface. The fit and finish on these lowers are the very best available for any manufacturer.

Gen 2 Improvements:

Upper Tension Screw – Allows users to fine tune the fit of the upper and lower receiver through the use of a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR-15 upper receiver. The rear take down pin spring hole is threaded to accept a plug that will make installation easy and hassle free.

Increased Mag well Flare – Allows for easier insertion of magazines and provides a sleeker look.
