Aero Precision Complete AR-15 Lower Receiver



Complete Lower Receiver for Completing Your Next AR-15

The Aero Precision Standard Complete Lower is the perfect base for your custom AR15 rifle to complete your rifle build quickly and easily. There is no need to figure out the installation manuals because specialists from Aero Precision have done the complete installation for you.

The Aero Precision Standard Complete Lower features an A2 pistol grip and M4 carbine stock that works with standard AR15 components and magazines. It is precision machined to meet the Mil-Spec tolerances for lower parts and has proven to have the highest quality materials and finish to fit your standard AR-15 upper receiver.

Nylon Tipped Tensioning Set Screw

This complete lower assembly also 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 AR15 upper receiver.

It also has an increased mag-well flare that allows for easier magazine insertion and a sleeker look.
