“I just finished putting together a new 6.8 upper using the Aero assembled upper receiver.
Fit and finish were flawless. The new 16" ARP 3R barrel slid in with a good snug fit without any play between the barrel and receiver. The Stag bolt carrier also works perfectly with this Aero receiver without any binding or rough spots.
When I get ready for another upper I wouldn't hesitate to purchase another Aero.”
“Got a Aero Precision complete lower w/ B5 furniture, was debating on a complete upper but decided to go w/ a stripped upper gen1 & build from there. Saw last minute a gen2 model AFTER I've purchased this, other than that it fits perfect on my lower. Thanks again!”
