Aero Precision M4E1 Stripped Lower Receiver – FDE Cerakote
The M4E1 Lower Receiver delivers billet aesthetics in a forged package. This custom-designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades, this custom-engineered design provides features that challenge much more expensive billet options and simplify the assembly process for the at-home builder.
M4E1 Lower Receiver Improvements:
- Threaded Bolt Catch Roll Pin – Allows for simple bolt catch installation and virtually eliminates the chance of damage to 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 – This allows users to easily install the Takedown Pin detent and spring using 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 also work with standard selectors.
