Suppressor thread gap

[HuntHarder]

My carbon 6 barrel's threads are longer than what my suppressor's female threads are. In other words, the can bottoms out on its threads, but there is still another 1/8" of exposed threads on my barrel. I have never ran into this issue, but feel like I should put some type of washer or crush washer there to make sure my suppressor has a firm and square stop. Is this common?

What can? What threads? SiCo ships a spacer washer with their rimfire cans for just that......

Seems a bit off. I've never ran into this. It sounds like the threads are bottoming out on your first baffle and that's not good.

I have no experience with C6 barrels, but I have multiple cans, and none of them need a washer. Can you take your can apart and look at the inside of the mounting threads?

sounds like your can's female threads didnt get finished all the way

Have you used this can before on a different rifle?

Does it bottom out or it just gets to tight to thread more? If the latter it could just be thread tolerances clashing. I had to chase the threads on a barrel with a thread die to work with my can.
