I just installed my first Tasco Red Dot scope on my new Marlin 60. It seems really cool and I can't wait to go sight it in. I disassembled and cleaned the gun today in anticipation of getting out to shoot, but the weather is crumby today. So, I guess it'll have to wait a day or two. Do any of you use red dot scopes on your 22? How do you like it? How hard are they to dial in?
