Manufactured by Aero Precision

The Aero Precision M4E1 Stripped AR-15 Lower Receiver is a fantastic foundation for a new AR-15 build. This lower receiver is machined from 7075-T6 forged aluminum and has an enhanced forging to deliver billet aesthetics in a forged package. Anodized black, it is compatible with all Mil-Spec AR-15 parts, including standard AR-15 components and magazines.

With a threaded bolt catch roll pin, the installation of the bolt catch is simpler, and it virtually eliminates the possibility of damage to the receiver finish during installation. The pin is included, and a 1/16" Hex Key is required for assembly. An integrated trigger guard eliminates the possibility of breaking the trigger guard tabs, and the rear takedown pin detent hole is threaded for a 4-40 set screw for easy installation of the takedown pin detent and spring.

Additionally, the Aero Precision M4E1 Stripped AR-15 Lower Receiver has an upper tension screw inserted in the grip tang of the lower receiver, which provides a fine tune adjustment for the fit of the upper and lower receiver. It also has a nylon-tipped tensioning set screw and an increased magwell flare that aids in quick and efficient magazine changes. This lower receiver is marked and milled to accept short-throw safety selectors, but it will work with standard selectors as well.
