I have a couple rifles with cherry bombs to attach the suppressor to. The first rifle I put the cherry bomb on with nothing a few years ago and frankly didn’t even know you were supposed to use rocksett at the time. I wanted to put the can on a different rifle and couldn’t get the cherry bomb off. I didn’t try anything crazy and probably could get it off somehow if I had to but it definitely wasn’t coming loose on its own. I ordered another cherry bomb to put on the other rifle and was reading about using rocksett to secure it. Is this really necessary? I have never had an issue with the other one coming loose.
