Howdy 'all,

Its almost ready, its almost time to hit the range and push distances with my 700 AAC. I got the scope, bipod, ammo, cheek rest, except Im having trouble with the muzzle brake. I got a standard DPMS muzzle brake and it fits the threading just fine except the seller never sent a crush washer to take up the extra 1/8 of an inch left on the barrel. A better way of saying this is that the vertical jets of the brake are canted est. 15-20 degrees left of vertical. Ill need a crush washer that can grounded down if needed. Any one have any recommendations on kind of material I should look for, or if there is a specific procedure for going about doing this?

The help is much appreciated.
