Thought this'd be nice for kids and folks to shoot so it won't cost me much (single shot 22's shoot cheaply) when somebody wants to start shooting. It's a Keystone Arms Chimunk Hunter pistol. I put a 4-16x Centerpoint MD on it and it appears to track fairly well through my grid-style bore sighter. I noticed that i only had about 8 MOA of up adjustment though, so i cut out the end of an old casino card, and stuck it below the back of the base, and voila--30 more MOA--
