Rings at a glance

Ring height

Choose the lowest height at which the objective lens of the scope stays clear of the barrel. Davika gives the height from the center of the ring to the bottom of the mount: its rings come in 30, 34 and 38 mm, its one-piece QD mounts in 34 and 38 mm and the cantilever mounts in 38 mm. The JK-N configurator offers low, medium and high.

Mounting the scope

1. Fix the lower ring halves on the base and put the scope in.
2. Slide the scope forward or back until you see the full image in your shooting position.
3. Level the reticle. See Bubble levels for rifle scope.
4. Tighten the ring screws evenly, in turns, to the torque given by the maker. Davika gives max 5 Nm for the clamping plate and max 3 Nm for the ring screws.
