I used the Optimus 9 universal suppressor on a pistol (Walther PPQ competition) with the ez-lock and noticed that it would come loose relatively easily. I believe I suffered a baffel strike during that one use and stopped using it thereafter. There's a small amount of damage to one baffle. The end cap doesn't even look like there's any damage.
However, I noticed that there were a lot of jacket shavings in the ar-15 FH mount when I removed the suppressor. In addition, there were uneven holes in the target.
Does anyone know how to get the baffle replaced?
