Anti-seize compound on threads

    My rifle builder advised that I apply a copper or silver based anti-seize compound (or even just a simple choke lube) to the muzzle brake threads before the first use of my Ultra 9 in order to avoid having the suppressor 'weld' itself (galling) to the brake. Do you agree or what do you think of this advise?

    It is not necessary

    I just sent in my 338 ultra because it is seized to the brake. I tried five times over the course of 10 days with various threadlockers to get the brake to stay affixed to the barrel so i could torque the can off but without success using the tapping method and a barrel vice and a strap wrench. It is completely stuck.

    What can I do to prevent this in the future?

    The most likely cause is that some carbon got on the threads. Typically just using a wire brush to reduce the carbon on the brake from time to time will do it. We almost never have cans get really stuck on the CB/BA brakes. We'll take a look at yours and see if something else is going on.
