I use a Winchester M69A .22lr that I got for Christmas in 1962, when I was 12...It currently is wearing an old El Paso Weaver K 8 scope, but I have a Leupold M8 4X that I plan to put on it...

I also use a stock early 70s vintage Ruger 10/22 with a Williams Fire Dot front bead and a Williams rear peep sight...My old eyes can't focus on regular open sights anymore, but a peep still seems to work fine for me..

I am also LUSTING for a CZ 452 in .17 HMR..A buddy of mine has one with an el cheapo 3x9 scope..I've borrowed it a couple of times and it is a real tack driver..
