Aero Precision M4E1 Stripped Lower Receiver - OD Green Cerakote, 840014618293, APAR600070C

M4E1 Lower Receiver Improvements:

Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included). 1/16" Hex Key required for assembly.

Integrated Trigger Guard - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon.

Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.

Threaded Takedown Pin Detent Recess - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).

Increased Magwell Flare - Increased the flare of the magwell to aid in quick and efficient magazine changes.

Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well.
