The Aero Precision 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.

Features of the Aero Precision M4E1 AR-15 Stripped Lower Receiver

  • 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.

    Excellent product and craftsmanship!
    This receiver was exactly what I was looking for. The quality of the product and craftsmanship were both spot on. I will be buying this again for my next build.

  4. PV

    Haven’t put this together yet, but this receiver appears to be well made and beautifully finished. Only problem, it was missing the special bolt hold open pin. A call to Aero Precision got a replacement.

  5. Brad

    I would buy this again. Perfect match for the FDE Aero upper

  6. Kelda

    What an innovative product!
    It’s crazy how far these things have come. I love the addition of the bolt release pin screw and the upper to lower end play screw.

  7. DS

    Top quality material precision cut, fit and finish. At the price offered should have bought two
