Ah, i see . . . your suppressor has a 5/8-24 threaded mount that's integral to the suppressor body. It can't be unthreaded and replaced with a different mount. Yeah, I'd go with Scotty's recommendation.

I'm planning on using this can on a lot of rifles and didn't want to have to buy a $70 QD brake for each one which is why I went with the direct thread model. That may, however, have been a mistake.
I use direct-thread for almost all of my rifle suppressors for that exact reason. You just need to make sure that you check the tightness of the suppressor periodically . . . and by "periodically" I mean every few shots until you're confident that it's not going anywhere.
Another option (not that it matters now) is to get the QD model. Put the QD brakes on any guns that you want them on. Then you can use an additional QD brake as a threaded mount; just leave it attached to the suppressor, and spin the whole thing on/off a threaded muzzle. This would give you the advantages of QD when you want it, plus the versatility of using it on guns without the QD mount.
