I use the gamo scope stop on my .177 whisper. Was the only thing I could find that did stop the creap on my centerpoint 9x16 scope. Mine actually doesn't even have the top screw tightened and it still is enough to stop any movement in the scope.

No problem oldpink,lots of bubbles around here (love my beans!). I suppose it made no difference to use the stop screw on that scope mount? What monster do you have that scope stop on anyway?darryl
