I always wished Ruger had done a .22 LR/.22 Mag Single Six with an aluminum birds's head grip (I know they never brought out a BHG in Al). Recoil wouldn't of been a problem, since there is no significant recoil in a rimfire.
Aluminum ejector rod housing. Adjustable sights. Make the barrel 3.75". The whole thing stainless, of course.
Lighten things up, to make for a better kit gun. I wonder if with these mods you could get a Single Six to down under 28 oz?
