I just bought a ruger 10-22 in well... used, abused is more like it but anyways im going to bring back some glory to this rifle and want to mount a peep sight insted of a scope. Does anybody know where i can get a peep sight that mounts with the two rear screw holes ? i think williams made one a while ago but i cant find it listed anywhere. man i cant wait for cabelas to get a shop in Canada so i can stop depending on other corporations who will remain nameless.
