PhotoBucket has blocked all sharing of photos, but you can get individual adaptors that are about one inch long that attach to your 11mm rail on the older .22s....I used a pair of them to allow the use of a red dot holo sight on my .22lr pistol...Google "11mm optic mounts" and I think you will find several in different sizes
Here are some on Amazon...https://www.amazon.com/11mm-scope-mount-Sports-Outdoors/s?ie=UTF8&page=1&rh=n%3A3375251%2Ck%3A11mm%20scope%20mount
