Not that I see. The scope is a 4x24 POSP. The siderail is a solid block of milled metal with only the tension clip for adjustment. Nothing else as far as I can see. My manual came in Russian, but the other manuals i've found online describe nothing what you are talking about.
EDIT: Yeah the method we described to each other in PM is the same one on Tantal's site. Still can't clamp down enough
