Suppressors TBAC ASR SR thread print

[TylerN]

Does anyone have the dimensions or prints for the threading used on ASR barrels for the SR mounts? This threading looks smart for SR mounts, reduces the OAL added and would make cleaning the crown easy. Looks like it should be easy enough for a Smith to cut 5/8"-24 or 3/4"-24 threads like this.

@Zak Smith , does TBAC have the dims for a threading job like this available? Asking here because I think others might be interested as well.

I don't know if we have a print. The ones that we've seen like this, a normal SR brake will fit. I think all those are 3/4-24.

it seems like the depth from the shoulder of the brake to the fins in the port areas is 1.5" total. So a bit less than that from the shoulder to the front of the barrel, say 1.4" in a 3/4"-24 thread seems like it should duplicate the ASR thread cut and fit with the SR brakes. Good call; all the AI barrels are 3/4"-24.
