I have a Bushnell 3x-7x Custom .22 scope that I use on my Marlin M-1 .22 and my Rem. Nylon 66. It's an older scope so I'm not sure of its availability. I am sure, however, you should pick one up if ever found. Perfect size and magnification. Eye relief is limited however, and you will need to get used to it. Is marked 18mm Japan on bottom. Good hunting!
