Looking at VX3 4.5x24x40mm $650 Mark 4 is more but other than turrets and black ring I can't tell difference?? I took both out and in lowlight vx3 actually was better ? Other then what already mentioned plus a different reticule I don't know difference except double the price. Educate me on what I'm missing I honestly don't know and apologize if this is beating a dead horse thanks Adam.
