Aero Precision M4E1 Threaded Assembled Receiver Set

Introducing the Aero Precision M4E1 Threaded Assembled Receiver Set - the perfect building block for your AR-15 rifle. This receiver set includes the M4E1 Lower Receiver in Anodized Black and the M4E1 Threaded Assembled Upper Receiver in Anodized Black for a sleek and unified look.

The M4E1 Lower Receiver boasts a number of features that make it stand out from the crowd. The Threaded Bolt Catch Roll Pin ensures easy installation of the bolt catch without damaging the finish. Additionally, the Integrated Trigger Guard provides a stronger and more rigid platform for building upon, eliminating the possibility of breaking the trigger guard tabs. The Upper Tension Screw allows for fine tuning of the fit between the upper and lower receiver, while the Threaded Takedown Pin Detent Recess ensures easy installation of the Takedown Pin detent and spring. Finally, the Increased Magwell Flare aids in quick and efficient magazine changes.

The M4E1 Threaded Assembled Upper Receiver is equally impressive. The enhanced forging gives the upper receiver a sleek "billet look" while the new picatinny profile blends seamlessly with Aero's Enhanced and ATLAS Series Handguards. The receiver also features M4 Feedramps, .250 takedown pin holes, and Laser engraved T-marks.
