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 .
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!
