Reticle Subtensions in Mil
Reticle Subtensions
The A PMR1 FFP IR MIL reticle is based on the milliradian,
usually shorterned to mrad or mil. A “mil” is defined 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 degreee 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
(Radians (.0573 degree) ) to get 3.6
inches which means 1mil equals to 3.6 inches at 100 yards

The APLR1 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 riflescope. Size of the first 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 magnification, the first focal plane
reticle provides ranging capability and valid holdover points at
all power settings, and finer details of the reticle at high power
for a shooter to engage a target with a higher level of precision
and confidence.
