Aero Precision M4E1 Threaded Assembled Receiver Set – Anodized Black
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 bolt catch installation and virtually eliminates the chance of damage to 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 users 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 gives the upper receiver a “billet look.”
- New Picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
- M4 Feed ramps
- .250 takedown pin holes
- Laser engraved T-marks
Note: Set may ship combined in one factory box, or in separate factory packaging. Uppers and lowers are not mated, and the fit/function is identical regardless of packaging.

Federal law requires that you be 21 years of age or older to purchase a pistol, stripped receiver, or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver, not a handgun or long gun. However, they are still “firearms” by definition and are subject to the same GCA limitations as any other firearm. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
