Aero Precision Enhanced M4E1 Stripped Lower Receiver - Anodized Black

Quality AR builds demand a lower receiver that can take on rapid fire and everyday stresses. Meet the Aero Precision stripped lower with a billet look but with forged strength. Feel the lightweight lower in your hand while knowing that its precision machining allows you to build with confidence. This Aero M4E1 lower comes with a host of different features:

  • Standard milled 7075-T6 aluminum
  • Integrated trigger guard for easy assembly
  • Accepts both short-throw and standard safety selectors

The manufacturer makes it easier than ever before to match your upper with the Aero Precision lower receiver. It comes with an upper tension screw fitted with a nylon tip, which grabs onto the upper receiver with some maneuverability. You're left with a perfect fit every time. Explore the Aero Precision M4E1 stripped lower receiver even further to discover other improvements that include an increased magwell flare, threaded takedown pin detent recess and threaded bolt catch roll pin. The Aero Precision M4E1 lower has been refined and perfected over the years, from the streamlined profile to an enlarged trigger guard opening with which gloves are no obstacle during use. This lower is compatible with most AR builds, so contact RTBA.com today for rapid shipment to your chosen dealer.

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.

5 of 5 Aero Precision M4E1 lower March 31, 2019
Reviewer: Jeff F. from NH United States  
I've built two MSR with the M4E1 enhanced lower receiver. One for a .223 Wylde and one for a 22 Nosler. Very nice lower receiver and matches up perfectly with AP's enhanced upper receivers. Fail Zero Nickel Boron BCG and some nice furniture and LPG and you have a solid build. I recommend Aero Precision to anyone looking for a great product at a more than fair price.
