Featuring a more subtle Aero 'A' Logo this Lower Receiver compliments your low profile rifle.

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 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.

Includes:

  • Stripped M4E1 Low Profile Lower Receiver
  • Nylon tipped tensioning set screw
  • Threaded Bolt Catch Pin
