Aero M4E1 STRIPPED LOWER RECEIVER – PURPLE ANODIZED

Literally dozens have asked for it- and we are here to deliver. Introducing our limited run of Black Friday 2023 purple anodized parts and components. Perfect for your next 3 Gun build, or just something a little more flashy. This part is finished with a Type 2 purple anodize that provides a large variety of contrast in different lighting conditions.

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.
