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 company, fast shipping and excellent price. I took a chance and boy am I glad I did. Aeroprecision stuff has excellent machine quality and fit.

Very impressed with the fit and quality. Excellent value. I wish Tom's Tactical offered an FDE MLOK 15" version.

Uses a standard AR15 barrel nut wrench (does not come with one)
(its hard to tell by the photo.. but the barrel-nut-looking is forged as part of the upper receiver. The actual barrel nut screws into that piece and is tightened using an AR-15 wrench

You WILL need a Torx T15 driver to tighted the hand-guard screws. (don't use the crappy harbor freight ones...they will break)

Rail is rather wide.

110% satisfied with this upper and rail! I was skeptical at first because of the price but man so glad I took a chance. Toms shipped my order the day after I placed it and it arrived 2 days later priority mail. Upper came boxed and unblemished and the rail was double wrapped and looked great! Looking forward to finishing my build and ordering a bcg and barrel from toms tactical.
