Does anyone have problems with the rubber falling out of the string suppressor? If so how to fix it? It hasent happend on my Airborne and yes I shoot the heck out of it, However I have seen it happen in the shop on a couple of Marquis, I called my Diamond rep and he said to try liquid nail, it dident work for to long. So I got some thin double sided sticky tape and trimmed to fit. It is holding up for now. Is this a common problem?
