DETAILS
The Aero Precision M4E1 Lower Receiver delivers billet aesthetics in a forged package. This enhanced forging is machined from 7075-T6 aluminum and compatible with all Mil-Spec AR-15 parts. A threaded bolt catch roll pin offers a simpler installation of the bolt catch and virtually eliminates the possibility of damage to the receiver finish during installation (pin included). 1/16″ Hex Key required for assembly. An integrated trigger guard eliminates the possibility of breaking the trigger guard tabs and an upper tension screw inserted in the grip tang of the lower receiver provides a fine tune adjustment for the fit of the upper and lower receiver.
