I took off red dot sight that had been mounted on my Ruger Mk. III 5.5-inch target pistol. I bought a new Weaver 2x28 pistol scope with rings to replace it. The pistol has Ruger's scope mount for Weaveer-type rings installed. When I attempted to mount the scope, its rear bell interferes with Ruger's OEM adjustable target rear sight. Rings lack less than 1/8 inch of height to clear the rear sight. I want to retain Ruger's OEM open sights.

How do I mount the scope with rings that came with Weaver's scope?

If this cannot be done, I'm thinking of buying, or trading for, rings that have that smidgen more height.

Since I have never mounted any pistol scope, I need recommendations.

If the consensus is a ring set, I am willing to trade - red dot included.

Taller rings

Don't forget about the eye relief issue.
