Muzzle OD/ Thread Pitch for T3 Lite/Superlite

[Whisky]

Probably looking to get a 300wm T3 Superlite from Sportsmans at some point and am curious what the OD is at the muzzle. I want to run a Gen 1 Micro Bastard for a brake. Thread pitch?

Thanks

All of the tikkas I've threaded have needed a 1/2:28 brake. I believe you actually have enough OD for a 5/8 brake but not enough to leave a solid shoulder for the brake to bottom out against.
