Aero Precision AR-15/M4E1 Stripped Lower Receiver

Machined from 7075-T6 aluminum, the Aero Precision® AR-15/M4E1 Stripped Lower Receiver boasts custom-enhanced forging for durability and aesthetics. A threaded bolt catch roll pin simplifies installation of the bolt catch, while an integrated trigger guard creates a strong, rigid platform to build on. The upper tension screw lets you fine tune the fit with a nylon-tipped set screw, ensuring a tight fit with any standard AR15 upper. A threaded takedown pin detent recess allows you to install the pin detentions and spring with a 4-40 set screw. Increased magwell flare facilitates fast, easy magazine changes, and this Aero Precision lower receiver is marked and milled to accept short-throw safety selectors while still working with standard selectors, as well. The Aero Precision AR-15/M4E1 Stripped Lower Receiver includes a stripped M4E1 lower receiver, nylon-tipped tensioning set screw, and threaded bolt catch pin.
