Aero Precision US Flag AR-15 Lower Receiver

Always Forward, Never Retreat! Aero Precision’s M4E1 Lower Receiver adds unique engravings to a striking design to show your national pride. This AR-15 lower receiver keeps all the enhanced installation features you’d expect, plus a “4 July” serial number and a stars-forward US flag on the right side of the magazine well.

This stripped lower is ready for a lower parts kit and a mil-spec stock assembly for a complete lower receiver build. Plus, the enhanced features like the threaded bolt catch pin and threaded rear takedown hole make installation far more accessible than comparable forged lowers.

Simplifies The Assembly Process

Aero Precision M4E1 Lower Receiver has an integrated trigger guard that eliminates the possibility of breaking the trigger guard tabs. The upper tension screw inserted in the grip tang of the lower receiver provides a fine-tuned adjustment for the fit of the upper and lower receiver.

It simplifies the assembly process for the at-home builder. The threaded takedown pin detent recess allows easy installation of the takedown pin detent and spring with the use of a 4-40 set screw. It also increased the magwell’s flare to aid in quick and efficient magazine changes.

The M4E1 is marked and milled to accept short-throw safety selectors but will also work with standard selectors.

Features And Improvements:

• Threaded Bolt Catch Roll Pin – Allows for simple bolt catch installation and virtually eliminates the chance of damaging 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 more robust, more rigid platform upon which to build.
• Upper Tension Screw – This 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 the 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 Magwell flare to aid in quick and efficient magazine changes.
• Marked and milled to accept short-throw safety selectors but will also work with standard selectors.
