Rings at a glance

Screw nut, lever or QD

Rings with a screw nut stay on the rifle. A lever or a QD mount lets you take the scope off without tools.

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.

For all rings by diameter, see Scope rings by diameter.

Frequently asked questions

Do these rings fit my scope?

Yes, if your scope has a 30 mm main tube. The ring diameter must be exactly the same as the tube diameter. You find it in the specifications of the scope.

Can I mount the scope myself?

Yes. Fix the rings, set the eye relief, level the reticle and tighten the screws evenly to the torque given by the maker.
