Yeah, I hear you about not messing with it. No, there wasn't anything wrong. I just wanted to take the barrel off to see if it would help me get the shroud off. I can't get the shroud off. Anyone know how? In terms of the alignment, I know it's aligned because I could see the set screw mark on the barrel lining up with the hole the set screw goes in, so everything is aligned. Shot it again today, and had a couple of sub MOA 50 yard groups. (and lots of bigger ones!), so maybe it was just me having a bad day yesterday. But there does seem to be flyers now when there wasn't before.
