Recently purchased another 6 Grendel barrel from a company called True Sports which is an outlet for Black Hole Weaponry. It is a Bull barrel 20" 1n8 Polygonal Rifling which at first glance i thought it was a smooth bore. This was a barrel blank chambered but not finished at all not even a barrel extension. A heck of a deal though. Have been working on loads and breaking the barrel in. The pic below lets me know the barrel is good
