I need a scope mount for my Marine Armorer built M1A for testing handoads and playing out to 600 yds. Have a new scope (Battlezone 6-19 and Weaver tactical rings. Thought I'd see if anyone had a DECENT but not outrageously expensive used mount they want to get rid of. Would love a Bassett low but that's a lot of $$ at the moment. Anyone got anything they have upgraded from?
