I will add that to prevent your suppressor from seizing on the mount, you can tighten it up til it stops turning, then back it off one click on the ratchet mechanism. There will be a slight amount of "wiggle" but it has no effect on accuracy or suppression in my experience. I had mine seize up one time and had to remove the adapter from the barrel and put it in a vise to get the suppressor loose.
Even though it's "loose" the ratchet mechanism does a very good job of keeping the suppressor from backing off. I think perhaps I tightened mine up some more while it was hot and then when it cooled there was no getting it loose. You can put a match mark on your suppressor and adapter with a regular pencil so you can verify it hasn't backed off. This way you won't grab it while hot and get burned.
