Anybody out ther have any experiance with the M14 (M1A1) "style" left side, receiver scope mount, for their Mini-14 (or 30) that slides into the bolt cover plate recess, and is held on by one large knurled knob ??? Any problems re-zeoring ??? Is it strong enough ??? Am thinking of using one on a Mini but don't think it is strong enough with the small "footprint" of the mounting base...AB
