Getting ready to order a bartlein 2b barrel and want to have a brake for range trips. Barrel diameter at 22" should be .654-.660 and I was told I'll need to use 9/16 threads, but the only brake I've found is the gen I micro bastard. For those that brake smaller barrels, is the thread advice I got sound right and if so are there any other brakes I can consider? Smith will be installing for me but would prefer a self timing if there is one that would work on a small barrel.
