Will this work with AeroPrecision M4 Enhanced Upper Receiver?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on March 25, 2022

The Aero Precision M4E1 Enhanced Upper Receivers are only compatible with the Aero Precision Enhanced and Quantum Series handguards. So this JL Billet Angled M-Lok Free-Float Handguard will not work with that upper receiver.

Q
Dusty, member, from MO, United States, asked on July 10, 2021

Does it come with a barrel nut? The description doesnt say one way or the other. Which is kind of an important detail to leave out.

Expert Answer
A
Answered by Tom B, Gear Expert, from IL, United States, on September 03, 2021

It comes with the barrel nut. "The MLA has a precision bore to fit the proprietary barrel nut which removes any unwanted play and ensures an exact fit!! Installation requires a 1-1/8" crows foot wrench (not included) for the barrel nut; standard AR-15 barrel nut wrenches will not work with this hand guard system. The hand guard is secured to the barrel nut by 2 10/32 allen screws, stainless steel key seat lock, and anti-slip helicoils."
