Aero Precision M4E1 Stripped Lower Receiver - Anodized Black
The 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 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.
A threaded takedown pin detent recess allows easy installation of the takedown pin detent and spring with the use of a 4-40 set screw. Increased magwell flare aids in quick and efficient magazine changes. Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well.

Deluxe lower for $100 or less

This new M4E1 lower is the best you can get in a forged lower. I will build my next two rifles (Valkyrie and Faxon 3 gun) with this lower. Every hole was perfect, beautiful finish on the smooth casting and nice trigger guard. I used a matching M4E1 upper om my Grendel build. Perfect line up. Looks billet with smooth edges.

WOW!! Aero knocked this one out of the park. The billet look for the forged lower price. This lower looks incredible and will be purchasing aero products again in the future.
