I've never had such trouble, but then I've never had a gloss scope mounted in the Optilocks. Make sure you degrease the scope and plastic inserts with something like Gun Scrubber. Be careful with the inserts as the Gun Scrubbercandissolve them. Spray it on a patch first and then lightly wipe the inside surface of the inserts once or twice. This will actually make theinsert ever so slightly tacky, which should help.

Personally, I like the Conetrols a little better than the Optilocks. They hold likea vise and are not as high as the Optilocks. I've got 3-9x40 Conquests on both of my Sakos. One is mounted in low Optilocks, the other in medium Conetrols. The scope mounted in the Conetrols is lower to the barrel and more to my liking.
