crush washer, No i have not tightened it yet, but i'm sure it's not going to work. I may have to sand as Loonwulf suggested.Is it a shim or a crush washer? Is it concave on one side?
could I add more crush washers, instead of sanding?It's a crush washer....I use a couple gammas.
Let me look through my muzzle break mounting crap when I get home. I may have some 1/2" shims.
If your feeling energetic, what you can do is sand (using a flat surface and even pressure) the wide side of the crush washer down till your within 1/8turn or so of true and then clamp up your barrel and tighten it the rest of the way down.
Ive never used peel washers, so cant realy comment on those.could I add more crush washers, instead of sanding?
also someone suggested peel washers, instead of crush washers.
That works as well, but make sure your clamping barrel well. Personally i dont realy like crushing, a crush washer that much, but its supposed to be fine.You tighten it until it’s finger tight and the keep tightening it until the logo is down. The crush washer is supposed to smash. Watch some YouTube videos on installing muzzle devices with crush washers.
Tighten some more and crush the washer, they usually have more than a full rotation of compression.
