Scope rings

(18 products)

Scope rings hold your riflescope on the rifle. They must match the main tube of your scope and the base on your rifle, and they must hold the scope at the right height. Here you find Picatinny rings and mounts, dovetail rings for the CZ 457 and CZ 600, a ring reduction and a mount configurator. You can choose rings from JK-N, Contessa, Davika and CZ.

Choose by tube diameter

The ring diameter must match the main tube of your scope exactly:

The JK-N polymer reduction turns a pair of 30 mm rings into 1 inch rings.

Choose by base

  • Picatinny rings clamp onto a Picatinny rail. JK-N makes them in stainless steel with a lever or a screw nut, Contessa in steel with a screw nut, and Davika in 7075-T6 aluminium as standard rings and QD Ergo mounts.
  • Dovetail rings clamp directly onto the receiver, without a rail. JK-N makes them for the CZ 457 in 1 inch and 30 mm, and CZ makes 30 mm rings for the CZ 600, also in a version for the medium receiver. See CZ 457 dovetail scope rings and CZ 600 dovetail scope rings.

Height and position

Mount the scope as low as possible without it touching the barrel or the action. JK-N offers a configurator where you choose the diameter, the height in low, medium or high profile, and the style of the base. Davika cantilever mounts move the scope forward, which helps on rifles where the scope would otherwise sit too far back, for example on AR style rifles. The Davika QD Ergo mounts come off without tools.

Torque

Tighten the screws to the torque in the product description, for example 2 to 2.5 Nm for the JK-N and Contessa rings. On the Davika mounts the clamping plate takes up to 5 Nm and the rings up to 3 Nm. Too much torque can damage the scope tube.

For rails, see Picatinny rails. For scopes, see Riflescopes. For a bubble level that mounts on Davika rings, see Bubble levels.

Frequently asked questions

Which scope rings do I need for my CZ rifle?

Rings with the diameter of your scope tube and the base of your rifle. On a Picatinny rail use Picatinny rings. On a CZ 457 or CZ 600 without a rail, use dovetail rings for your model.

Can I use 30 mm rings for a 1 inch scope on my CZ?

Yes, with the JK-N reduction from 30 mm to 1 inch. Otherwise choose 1 inch rings.
