Excellent upper. by Deen, Verified Owner, March 1, 2020
Fit, finish, and accuracy are everything you’d expect from Aero. 5/5 if it were to have a 10” rail. The ergonomics of the R-One handguard are fantastic. Rail feels great in the hand and the fitment is perfect. Very lightweight. Would def recommend.

Aero Precision M4E1 5.56 by Mas Casa, January 13, 2020
I bought this as a secondary 5.56mm upper to swap with my Aero Precision M4E1 300 Blackout pistol. Fit and finish are excellent. The Atlas R-ONE handguard leaves nothing to be desired. Wish AP made a version with an A2 front sight post!
