Aero Precision M4E1 Enhanced Upper Receiver - APAR600201AC
Out of stock
Our state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superiorengineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 Screws Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling.
Ease of installation – Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail Screws Within minutes you have a modular, free-floated rail.

Really like the quality of the upper receiver, highly recommend
USRock solid
I needed a good foundation for a Valkyrie build and I decided on this. I really like the way the hand guard mount is built into the upper (be sure you get the correct style hand guard). Not having to clock the barrel nut is a plus too. Fit and finish is excellent so assembly only took minutes. Could not be happier and I definitely recommend this upper.
