Aero Precision M4E1 Stripped Lower Receiver, Purple Anodized

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 simply the assembly process for the at-home builder.

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 girp tang of the lower receiver.  This provides a tight fit with any standard AR15 upper receiver.
• Threaded Takedown Pin Detent Recess- Allows users to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw.  (No more launching detent 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 selections, but will work with standard selectors as well.
