I have had nothing but good luck with old weavers. Right now I have a K6 on my handi heavy 223, K4 on my Ruger 30-06, and a really old G6 on my old Marlin 39. I swear, I'd rather buy an old used Weaver for $75 or less than pay 3 to 4x that for a new anything. You can't beat a pawn shop/gun show Weaver.
