Fit a 1 inch (25.4 mm) scope on a 11 mm dovetail
A 1 inch (25.4 mm) scope on a 11 mm dovetail: the ring size, the pattern to match and how ring height clears the objective.
Rings must match the tube. A 1 inch (25.4 mm) scope needs 1 inch rings; a ring cut for another diameter either will not close or lets the tube slip. The ring pattern must also match the 11 mm dovetail.
Measure the groove first: real 11 mm dovetails run 11 to 13 mm. On a spring air rifle the two-way recoil walks a scope forward, so use a ring set or adapter with a scope stop. Once the diameter and pattern match, ring height decides objective clearance: low rings for a small objective, taller rings as the bell grows.
