I'm looking at building a 6 ARC. I have a 12.5" Grendel but its kinda slow. The gun will be for coyote hunting hence the shorter barrel, it will also be suppressed. So I'm thinking of swapping the barrel for the new kid 6 ARC. I don't see a lot of short barrels out there but I found Shaw Barrels has some. Curious has to how the quality is with Shaw? Their price seems on the low end.
