Okay, looking for some consensus.  I ordered and received one of Griffin's 9" 300BLK HEDP barrels. I put a muzzle device on it before installing, so i could check suppressor alignment with an alignment rod.  The rod wouldn't even go in the barrel, couldn't get past the muzzle face.  I measured my alignment rod and it comes in at .298, which means the muzzle is even smaller. I flipped the barrel around real quick and put it in the other end, and slid right in, smooth as butta! 

I sent an email through griffins website about a week ago, but have received no response.

You guys think it's safe to put it on, and shoot with it through a suppressor? I know Broughton makes tight bore barrels, but suppressors aren't easily replaced if something goes sideways.
