I have an AMT 25/22, basically an all SS 10/22 before Ruger made one. It's got a 3/8" dovetail milled into the top of the receiver and isn't drilled/tapped. I'm planning to mount a 3-10x42 NF SHV non-ilium (for the parallax adjust) on top. Warne makes a set, so does Talley. Anything else I should be considering?
