Aero Precision M4E1 Threaded Assembled Receiver Set - FDE Cerakote

The Aero Precision M4E1 Threaded Assembled Receiver Set is composed of the Aero Precision stripped lower receiver with an integrated trigger guard, and an assembled upper receiver with an enhanced forging.

The M4E1 lower receiver boasts features that allow for easy installation and fine-tuning for a tight fit with any standard AR15 upper receiver. The threaded bolt catch roll pin facilitates simple bolt catch installation and eliminates the possibility of finish damage, while the integrated trigger guard creates a rigid platform for construction. The upper tension screw permits users to fine-tune the fit of the upper and lower receiver, ensuring a secure and stable base. The threaded takedown pin detent recess streamlines Takedown Pin detent and spring installation, preventing detents from launching across the room. The increased magwell flare guarantees fast and efficient magazine changes.

The M4E1 Threaded Assembled Upper Receiver features an enhanced forging that gives the upper receiver a "billet look," a new picatinny profile that harmonizes effortlessly with Enhanced and ATLAS Series Handguards, M4 Feedramps, .250 takedown pin holes, and laser engraved T-marks.
