Rainier arms 9mm barrel - Rainier Arms AR Select 9mm Barrel

Good finish, not had a chance to test accuracy just yet. But I'm sure it's up to par. Only issue I found out the box, is there are no markings on the barrel of any sort. Other barrels I've used from Rainier Arms and other brands at least have their brand and or caliber/twist rate stamped on the barrel. For me, I have to take OpPl word that it's actually that brands barrel. I selected yes to recommend, but low stars for no markings.
