I'd say a shim or a flip is required. and a better clean.
I'm kicking myself for not checking this earlier.
So easy to do, I got a full turn and extra out of it. That might be responsible for less than stellar accuracy hey?
I guess I'm posting this to show m14 newbies ( like myself) not to take anything for granted with their rifle and spend 5 minutes to check it.
On a side note, I worked at the GD flash hider for two hours, it must have been "bring your kids to work and practice welding on na1lb0hm's flash hider day" when this thing was built. I think I found one of the more difficult ones to remove, starting to think that it's not actually slipped on there and I've got a rare "flash hider actually machined as part of the barrel"
Used a barrel vise, hammer,punch and drill and still haven't got it. Going to try switching to chisel and everything tonight.
