Jeremey, member, from TX, United States, asked on May 05, 2020

The caliber designation on this is .308, but the platform designation is AR-15. would this work for 5.56NATO?

Manufacturer Answer
A
Answered by Aero Precision USA, Manufacturer from WA, United States, on May 19, 2021

It will not. The M5 is an AR308 pattern rifle. For a 5.56NATO build you should look at the M4E1 Enhanced upper receiver.

ADLEE2, member, from LA, United States, asked on March 18, 2020

What is enhanced about this upper?

A
Answered by Patriotic Realist, member, from OH, United States, on April 02, 2021

The upper has a specialized extension and barrel nut which works with enhanced compatible handguards. The handguard is much easier to install and get/keep straight. I believe it also provides additional heat sinking for the barrel at it's hottest point versus a standard barrel nut design. Just google some pics of "Aero Enhanced Barrel Nut" and "Aero Enhanced Upper" to see the difference. The compatibility with the Atlas handguards makes it worth it for an "enhanced" upper. The Aero Lower Enhanced Receivers have a number of features that make them better than standard.

Is it compatible to a .308 80 percent billet lower?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on August 02, 2022

The Aero Precision M5E1 .308 Enhanced Upper Receiver is designed to fit Mil-spec 308 lower receivers and should fit your 80%. However, due to potential variations in 80% lowers that can be out of spec, we cannot guarantee perfect compatibility.
