Got these two in a trade today. I gave a new stainless 10/22, and got these two. Ruger serial number lookup shows the MK I as made in 1972, and the SS as 1967. SOmeone please correct me if i got it wrong. They look great, and only need some minor cleaning. I have read that MK II mags will work in the MK I. Is that correct?
