30 mm Blaser scope rings

This collection contains the JK-N modular scope rings for rifles with a Blaser base, here for scopes with a 30 mm main tube. JK-N makes them from steel in the Czech Republic, with a black anti-reflective finish.

What you configure

• Height: low, medium or high. Choose the lowest height at which the objective lens stays clear of the barrel.
• Base length: short (114.2 mm) or long (139.2 mm). Both fit any Blaser interface. A long base gives you more room to position the scope.

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 other diameters, see Scope rings for Blaser base.
