Gap between suppressor and shoulder

[00wingzero1980]

Have this barrel. When mounting WOLFMAN using 1/2x28, the suppressor stops at the end of the thread. Doesnt contact the shoulder because there are no threads all the way to the shoulder.

Would it be fine to shoot?
Would I need a spacer?

Or the threads on this barrel is too long in lenght...and the tip of the barrel in hitting the inside of the wolfman fixed mount...

Thanks

Yes you need a spacer silencerco has thread on ones for like 10 or 15$

depends on if the muzzel is square. Best to use a spacer
