Includes:

  • M4E1 Lower Receiver in Anodized Black
  • M4E1 Threaded Assembled Upper Receiver in Anodized Black

M4E1 Lower Receiver Features:

  • 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).
  • 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.

M4E1 Threaded Upper Receiver Features:

  • New enhanced forging that gives the upper receiver a "billet look"
  • New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
  • M4 Feedramps
  • .250 takedown pin holes
  • Lazer engraved T-marks

    Sloppy

    Posted by Unknown on Jul 18th 2019

    Item was shipped extremely fast. Could not be happier with E-Arms. Unfortunately this lower and upper receiver set is the sloppiest fitting upper and lower I have ever owned. Will stick with Colt or BCM in the future.

    M4e1 receiver set

    I ended up sending this to my ffl and had the set quick and without any issues. Fit and finish is good and the added benefits of this set (threaded bolt catch assembly, threaded forward assist spring pin, receiver tension screw) really set this aside from anything in this price range

    Best deal on the internet

    Posted by Stan on Dec 12th 2018

    I have bought more than a few of these sets, they are hands down the best sets you will for the money, and E-arms deals are the best I have found, and I have searched hi and low for cheaper sets, of this quality, I have to find any that are anywhere

    Trouble with reciever and Aero refused to warranty

    Posted by TCup on Jun 22nd 2018

    Got the set, fast shipping. Got a 4-40 1/8” set screw for the rear detent. When screwing it in it made it halfway and stopped. Thought it was cross threaded but it wasn’t. Called Aero and they refused to warranty it saying I caused the damage. I’m shocked, won’t buy Aero products anymore.

    High quality and affordable receiver set

    Posted by Jaime on Jun 11th 2018

    This was my first Aero set after seeing good things from others. Fit an finish were top shelf. There is no slop or play in anything. Threaded bolt catch takes care of the scariest part of receiver building. Excellent price too, barely ore than a quality lower or upper by themselves.
