Suppressors 9/16x28 min barrel muzzle diameter?

[XTREM HTR16]

Have a hunting rifle with a barrel that measures .635" at the muzzle. Would there be enough meat to thread it 9/16x28 and use a TBAC CB?

Per TBAC's thread diagrams (https://thunderbeastarms.com/tech/thread-specifications), that's not enough meat for a shoulder. A jam nut is probably the best solution for you.

Never use a jam nut with a suppressor!!!! Thats asking for baffle strikes. There is nothing to hold a jam nut square. 9/16 threads need at least .660 .

TBACRAY, do your muzzle devices work to index on the muzzle instead of a shoulder? If so, what is the minimum thread length to do that?

If that works with your muzzle devices, he could just go with the standard 5/8-24 indexed on the muzzle.

They index on the shoulder

We can also do muzzle face mount brakes if we do it here at the shop, in some cases where the muzzle OD is too small for a shoulder

Ray and Zak,
So I need .660" at the muzzle for 9/16" threads, regardless of 9/16x24 or 9/16x28? That's what I'm reading/assuming but want to clarify/verify.
Thanks!

For a 9/16" (24 or 28). Face mount brake, you need .560"+. Shoulder mount, you need .660"+.
