Muzzle brake install question? I bought a sure fire muzzle brake and with the crush washers installed I will have to (after hand tight) tighten the break almost or a little more than 3/4 turn to get it indexed correctly. Is this way to much? Any other options. 5/8x24 Bergara rifle. The instructions states tighten to 90 degrees but no more than 450 degrees which that seem very excessive. I only have one other braked gun which had a custom muzzle break done and was timed by a smith and the thing fits like a glove and is timed perfect with just barely any pressure for tighten. Can you get other or thicker crush washers or thinner crush washers?
