Just a heads up for you. Ballistic Advantage makes the Aero barrels. They're owned by or partnered with Aero a couple years ago.
Barrels are generally a little less expensive direct from BA. And you can look through their full selection. If they say it has the gas block included, you can call them and have them leave it off. Or just go ahead and use.
I bought their 8.3" Hanson profile premium in 300 BO for my build. I'm using a SLR adjustable gas block and an H3 buffer. It's cycling everything I've fed it so far, subs and supers, at about 5 o'clock. It's a little slow. Gonna try adding gas, and if need be switch to a lighter buffer to get it to 3 o'clock ejection.
