Is the new brake threaded larger than the old one? I am lost on the set screw.

maybe im wrong but i think that is so that you can index the brake correctly and then tighten the set screw so that the brake wont rotate. so that teh brake doesnt need to be tightened zll the way down to the end of the threads? that is my guess.

that gun is sweet by the way!

No , it is the same thread size. It just makes it easier to keep it in place, index it and to remove it for cleaning.There was no work done to the barrel threads of the previous brake. They made another brake work with out messing with the previous threads or barrel length.

I was hoping the brake indexed square when bottomed on the tennon.

I would like to here if screw tension on the brake changes poi. I doubt it will, just curious.

The brake does index square upon contact( Just snug ). But brakes with a flat on them are whole different creature than brakes in the round and that's due to the tension required to keep it in place but also square at the same time. The set screw allows me to screw the brake on untill it touches snug   , where it is square and set the screw. Anyone who has used brake much knows there is some give to any metal involved, barrel/ brake and over tightening of a brake that indexes correctly, especially with brakes with a flat. They will go past there index point and will not longer index correctly where the flat is noticeable past it's index point. With round brake, I can care less doesn't matter the hole pattern is equal all the way around and you cant  see it visually.The only way to make a brake index up correctly would be to do it at a certain inch pound of torgue and never go beond that, well that isn't happening with me, for speed, cleaning and simplicity. Screw the brake on untill it touches snug and indexes, set the screw with maybe a 1/8 - 1/4 turn and be done with it.
