Reticle Subtensions
The APLR2 FFP IR MIL reticle is based on the milliradian, usually shortened
to mrad or mil. A “mil” is dened as “one thousandth”, or 1/1000. A mil
is 1/1000 of a radian ( a unit of angular measurement). Since there are
6.2832 radians in a circle, and each radian is chopped up into a thousand
pieces, there are 6.2832 x 1000 = 6,283.2 mils in a circle. Since there are
360 degree in a circle, we can get 360 degree/6,283.2 mils=0.573 degree/
mil. If the target is 100 yards ( 3600 inches) away, we can use 3600 Tan
(.0573 degree) to get 3.6 inches which means 1mil equals to 3.6 inches at
100 yards
The APLR2 FFP IR MIL reticle is located at the focal plane in the front of the
erector tube which is a key part of achieving variable power inside the rie-
scope. Size of the rst focal plane reticle grows or shrinks at the same ratio
with the changing size of the image of your target when you try to zoom
in or zoom out. Since the size of the reticle remains constant compared to
your target regardless of the magnication, the rst focal plane reticle pro-
vides ranging capability and valid holdover points at all power settings, and
ner details of the reticle at high power for a shooter to engage a target
with a higher level of precision and condence.
