Aero Precision M5E1 Enhanced Upper Receiver - Anodized Black (BLEM) - APAR308504BAC

Aero Precision’s state of the art M5E1 platform starts here, with the M5E1 Upper Receiver. The M5E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, Aero Precision has 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 Aero Precision is 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 M5E1 upper, tighten it using the included barrel nut and slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.

Note: Aero Precision is listing these under a Blem SKU meaning that they will have a very minor cosmetic blemish of some kind that will in no way affect the function of the product. In our experience, this typically amounts to a minor run-in the anodize or a slightly different color variation than the norm. In most cases, we can not see why they are called blems. They have even told us that the blem in the finish could be hidden away due to it being on the internal surface of the receiver.
