I've not had any issues what-so-ever with my Optilock rings / inserts. But, the scope (Kahles CL) is a matte finish not gloss. Plus it's on a 30/06 that isn't a fierce recoiling rifle with 180 grainers anyway. Be cautious on over tightening so as not to damage the tube. What about rubbing some fine steel wool on both sides of the inserts to "rough it up a little" then re-installing? Just a thought.
