What to fit it with

You can buy 30 mm rings cut for an 11 mm dovetail, which clamp the groove directly, or fit a dovetail-to-Picatinny adapter and then use ordinary 30 mm Picatinny rings on top.

Measure the dovetail, since the real width runs 11 to 13 mm. A spring or gas-ram air rifle recoils in both directions, so use rings or an adapter with a scope stop or arrestor pin to stop the scope walking forward.
