Aero Precision M4E1 Stripped Lower Receiver - Bordeaux Red Anodized

Product Description: Aero Precision APAR600590C: 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.

Finish: Bordeaux Red Anodize offers a dark red anodized finish that is sure to make your next build stand out from the rest. The shade of red offers a unique color, without the "loud" appearance traditionally found on red anodized finishes. This finish is a perfect foundation for your next competition gun or AR15 post.

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, providing 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.
• Increased Magwell Flare: Increased 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.
