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 superior engineering, 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.

Awesome upper Review by Ty
I love the upper, looks great and no issues with function or fit with my RRA lower or Integrity arms barrel. It was really easy to install the 15" enhanced handguard as well. Very sturdy. I will go with these for future builds for sure. (Posted on 11/16/2016)
Good stuff Review by Ty

Wow, I wonder what a non-blemish would look like! Review by James
I got lucky and bought a blemished upper and, well, I can't see any blemishes. This looks awesome! Can't wait to finish my build and go shoot. (Posted on 4/21/2016)
Great Upper Review by jstcynske
I am in the process of an FDE build and loved the look of the Aero Enhanced upper. After receiving it, I will be ordering other parts from them as well. The finish is fantastic, and the overall quality is great as well. (Posted on 6/17/2015)
Excellent product Review by Brett
This upper came in excellent condition. The cerakote finish is very nice. I got a 9 inch keymod enhanced handguard to go with this. It fit perfectly with it. There is no doubt this is the strongest most durable way to go with an upper. (Posted on 6/6/2015)
