The old Weaver rail w 3 or 4 slots is low. Zee rings might scratch receiver. Slightly taller is the newer version w slots all over ( pic rail ). You can go that way and run Zee lows if objective clears.

I have a fingergroove sporter (70).....and think mediums a little tall. Got some lows last week. Rear sight folded. May have to remove or just get GM sporter bbl. Mediums clear the freedom vx efr 3-9x. But the scope looks horrible on an old classic

Too tacticool
