I just picked up a Terminator T4 brake and want to try it on my Proof barreled 338 LM AI. Currently using a APA Gen 2 Fat Bastard which is self timing. I don't want to send the barreled action back to my smith for the indexing of the T4. Is the use of a crush washer my only option or is there a nut available?

What's the thread of the muzzle? You may be able to buy shim washers from McMaster-Carr to effectively time the brake.
