Both the AMX and AMX IR glass etched reticles are based on the spacing of a 10x Mil Dot. The AMX offers multiple aim points useful when shooting air guns with loopy trajectories. Half Mil Dot spacing on the lower post provides increased aim points for long shots. The horizontal bars are calculated at 0.5 1.5 2.5 3.5 and 4.5 mil spacing. Hollow posts are segmented into mil spacing and can be used for bracketing.
