Limiter pin and dovetail rails
The limiter pin of the Optilock base fits perfectly into the integral tapered dovetail rails on the Sako actions. The combination of the dovetail rails and Optilock mounts is the smartest way to mount a scope on a high-power rifle. Integral tapered dovetail rails are positioned on the Sako rifle's actions and feature a limiter pin slot for Optilock bases and ring mounts.
