The scope chosen by the United States Marine Corps as standard equipment Scout Sniper Day Scopes. It includes all the features of the 3–12 x 50 PM II LP, plus a sepcially designed "double-turn" counter-clockwise elevation knob with tactile clicks every 10cm or 1 Mil. In place of the color-coded window, it has a ring-style indicator which raises after the first full rotation of the knob. This can be both seen and felt by the operator, giving clear indication of which scale to read on the turret. There is a total of 220cm/22Mils/79.2" of elevation adjustment.
