Aero Precision M5E1 AR-10 Upper Receiver + 15" Free Float Rail Combo Set

The state of the art M5E1 platform starts with the M5E1 Upper Receiver. The M5E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Since the rail mounting surface and upper are of the same forging, not only is it a stronger system, but it also provides for easy installation of the gas tube with a pre-aligned gas tube hole. Additional lightening cuts save weight and allow for more efficient cooling.


Easy barrel installation - Simply insert your barrel assembly into the M5E1 upper and tighten it using the provided barrel nut and wrench. Then slide your rail on and tighten the screws. Within minutes you have a modular, free-floated rail.


The state-of-the-art Enhanced Upper Receiver combines the handguard mounting platform with the upper itself, condensing the parts needed to mount a free-floated handguard to a mere 8 screws. Our Gen 2 proprietary handguards are designed specifically for our Enhanced Series Upper Receiver and are meant to be purchased together.

Excellent service! Ordered on Sunday, shipped on Monday, and received on Wednesday. Can't beat that. The upper and handguard look very good. Fit of handguard to upper is excellent. The fit of the upper to my DPMS lower wasn't perfect. The rear takedown pin would not fit through the hole on the rear of the upper. With that being said, it allowed me to file and hone the hole for a perfect fit. I am very happy with the outcome.
