Added this somewhat rare Ruger 10/22 to the stable. It's called a Sporter "Finger Groove" and was manufactured from 1966 to 1971. Ruger continued to make Sporter models after 1971 but without the finger groove. After doing a little research, these rifles command a premium when in good shape. I'm thinking about topping it off with same era Weaver scope. I can't wait to run some rounds through it.
