Aero Precision M4E1 Threaded Assembled Receiver Set – Anodized Black
- 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.
