Aero Precision M4E1 Lower Receiver Features:

The Aero Precision M4E1 Lower Receiver delivers billet aesthetics in a forged package. It is machined from 7075-T6 aluminum for durability and compatible with all mil-spec AR15 parts. It features an integrated trigger guard enlarged for ease of use with gloves and an upper tension screw to eliminate rattle and play between the upper and lower receiver. The magazine well features increased flare compared to a Mil-Spec lower to aid in quick and efficient magazine changes under stress. For ease of assembly and installation the bolt catch pin hole is threaded, as is the pin hole for the takedown pin detent. This model has a black hardcoat anodized finish and the selector markings are compatible with standard or short throw selectors.
