Optilock bases and rings are machined from a solid block of steel, Cr-Mo alloy or stainless, just like our rifles. The front bases have a solid angled left side and a similarly angled right side with a clamping device. This base design connected to Sako rifle´s integral dovetail rail allows you to adjust the horizontal position of the scope objective end without touching the scope adjustment. Comes supplied with required allen keys.
