Hey guys, I got my CNC Warrior Knurled muzzle brake in yesterday, and when I went to install it, it gets tight just short (1/4" or so) of the detent pin. When I back it up a turn to get the notch to align with the pin, it is very wobbly/loose. Should I try and wrench it the last 1/4"? Or is there some kind of spacer I should use, like a crush washer? Or do I try and drift the sight post back a bit?
