Very good universal dovetail scope mount for rimfire rifle - Warne 22 Caliber Medium Scope Rings

As the product information states, these mounts will fit both 3/8 and 11 dovetails. All you have to do is turn the small removable piece over and it will fit the other size dovetail. I use these on both American and European made rimfire rifles and they work very well. You don't need tons of torque on a rimfire so it is not necessary to use so much force that you strip the screws. I will continue using these for my dovetail rimfire rifles.
