TBAC shows that .600" dimension on their drawings but I'm not sure how they arrived at that value.
I'll ask Ray the next time I talk to him. I chose .550" after checking a number of brakes and comps, both plain and suppressor mount type, finding a few that got really tight with .050"+ tenon remaining before shoulder. With rimfire cans, there are a few cans that have a blast baffle cone tip barely 1/2" in. As for .450" on pistol barrels, that was more of a "looks about right" decision.
PCCs? Pistol Caliber Carbines?
