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 that challenge much more expensive billet options, we have added several functional features to the lower receiver to 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 Lower Receiver
  • Nylon tipped tensioning set screw
  • Threaded Bolt Catch Pin

    M4E1 is awesome

    After seeing the M4E1 quality, features and price, my friends wonder why they paid twice as much for something with a fancy name and o picture on the side

    Good Product and Experience

    Posted by Unknown on Jun 21st 2018

    I ordered the receiver on Monday and it was delivered to my FFL on Thursday. The lower itself arrived in good condition, with two small blemishes that I can live with. Assembly went smoothly, and the threaded mag catch pin was a surprisingpy useful feature.

    Best Value On the Market

    Posted by David Clark on Apr 24th 2018

    I was lucky enough to snag two of these on sale! Impeccable finish, forged strength, low price, and awesome look define this piece. What really sold me was the built-in trigger guard with relief cuts and the flared magwell. I see little reason to buy a poverty pony or an expensive billet receiver when this option is available for under $80 shipped.

    Now if only Aero would make a comparable 9mm lower.... B-)

    One of the best bang for the buck and higher quality lowers on the market.

    I have to admit I usually go the cheaper route on my lowers but these Aero M4E1s are worth the extra money for the additional features and billet look. My first order from E-ARMS and definitely not my last. Shipped fast and arrived quickly. I wish E ARMS would sell some already assembled lowers with some nickel born or polished trigger options in the future. Also some other color options would be sweet. Thanks again E ARMS.

    Aero M4E1 Stripped Lower

    Posted by Unknown on Apr 4th 2018

    Was lucky enough to get this before it went out of stock. I paired it with an AERO upper and the fit and finish were excellent. It looks like one piece when put together. It has the threaded bolt roll pin which I loved. I have seen some reviews that are may not be positive of this feature, but I am sure that they have not tried it. In either event, I am not going to war with it so no worries for me. Great product, it was my first build and not one scratch.
