I bought an upper that was advertised with an Aero Precision barrel. After receiving it, I have doubts. Can anyone tell me how Aero barrels are roll marked? Specifically does "Aero" get stamped anywhere on the barrel?
It's an 18" 6.5 Grendel, some sort of black coating with flutes. Near the muzzle it's roll marked "6.5 Grendel 1:8". NO other engravings/stamps/markes are on the barrel.
