Product came defective - Rival Arms Glock 19 Gen 5 Precision Threaded Drop-in Barrel

I guess their was a rush when producing these barrels that quality control went by the waist side. It’s supposed to be riffled 1:10 twist / 6 groove, but the barrel is completely smooth inside and looks the manufacturer never finished the job. Waiting on a return label for a bout a week already and nothing yet. I just hope they have more in stock because I would hate to have to wait another 5 months to get one!
