Due to this scope’s internal prism design,
when viewed at certain angles and
distances the reticle may appear canted
(tilted to the left or right). Each individual
scope has been checked for correct reticle
presentation and illumination. The scope
should be mounted on a rie and viewed
using the correct eye relief, and the reticle
will appear in its proper alignment.
Our high quality anti-reection objective
lens attachment is also available, part
numbers PA5XKF and PA5XKF-FDE.

ACHIEVING A CLEAR RETICLE PICTURE
Setting the adjustable diopter ring (E) at the rear of the eyepiece is a critical rst step to successful precision shooting.
Looking at a featureless light background like a clear blue sky or blank wall, the reticle should appear sharp and crisp.
If it does not, you need to adjust by turning the diopter ring (E). Look at the scope with quick glances and adjust until
the reticle is clear at rst glance. This is a one-time adjustment. Because everyone’s eyes are different, the ideal
adjustment will vary from person to person.
The reticle details may appear small when not looking at the ranges they are set for, beyond 300 yards. Shooting at
those ranges is best done from a well-supported position.

RETICLE
ILLUMINATION
The illumination knob on the top of
the scope is marked with numbers of
increasing brightness from 1 to 5 in each
direction from 0 or “off”. There are two
“off” settings, divided between 5 red
partial illumination settings and 5 green
partial illumination settings. The knob
cap unscrews counter-clockwise, holding
a CR2032 battery with the positive (+)
side facing towards the cap. Reticle
illumination at the lower settings is
useful in low light situations like sunrise
and sunset. The highest two settings
are “daylight bright” settings. Using
these settings in low light situations
will overpower your eye’s ability to
see the target and make the reticle
appear distorted. The right amount of
illumination creates a clear contrast
between the reticle and your intended
target, without straining the eye.

THE REMOVABLE
BASE AND SPACER
THE REMOVABLE
1913 MIL STD RAIL
Thread locker is recommended on the base and
accessory rail screws. The 3mm hex base screws may
be removed for use with AR-15 carry handle upper
receivers in conjunction with our Steel Knurled Head
Thumb Screw, part no: 92581A320.
The 5x Prism Scope features a removable spacer in
between the base and the scope body. Use the spacer
for rearms with straight line stocks such as AR-15s.
Removing the spacer brings the scope body lower for use
with rearms with stocks located lower than the receiver,
like AK-47s. The scope body is compatible with full size
ACOG®style mounts with or without the spacer installed.
The top mounted 1913 MIL STD rail (B2) is useful for mounting a reex sight or other accessories above the prism scope. It
is removable by turning the four T10 torx screws (A1) counterclockwise and removing them. Removing the 1913 rail shaves a
bit of weight and bulk from the scope. To replace the 1913 rail, torque the screws to only 5 inch pounds after applying a small
amount of blue thread locker. Do not overtighten the screws, this is a very small amount of torque!

GETTING TO KNOW
THE ACSS®RETICLE
The ACSS®(Advanced Combined
Sighting System) is a giant leap
forward in reticle design that uses
bullet drop compensation correlated
with range estimation, wind and
moving target leads in one simple
to use system. The ACSS reticle
increases rst hit ratio and decreases
time on target dramatically. It is a
two-part reticle that allows you to be
very fast from 0-300 yards and very
accurate from 400-800 yards.

DIALING IN FOR YOUR BARREL LENGTH AND AMMUNITION
Using a bipod or sandbags, preferably on a bench or in the prone position, adjust your turrets to dial in your point of impact
to the center dot. Each click is 0.33 MOA, or 0.33 inch at 100 yards.
Your point of impact will vary depending on type of ammunition, barrel length, and altitude above sea level. For 5.56 NATO
and 5.45x39 loads, match your ammunition type and barrel length with your altitude above sea level, and zero your scope
at the distance indicated. For other loads, nd your bullet weight and velocity and zero your scope at the distance indicated.
Plus (+) and minus (–) numbers indicate desired bullet impact in inches above or below your point of aim. For example, a
shooter ring M855 using a 16” barrel will want to sight in a half inch high at 1,000 ft. above sea level, dead on to point of
aim at 2,000 ft. above sea level, and a half inch low at 3,000 ft. above sea level, zeroing at 100 yards.

GETTING TO KNOW
YOUR BULLET DROP
COMPENSATION (BDC)
Gravity will affect your bullet’s trajectory (or
path). The BDC ladder starts at the center dot
and nishes at the 800 yard mark indicated
by the number (8). Simply aim using the hash
mark that coincides with the range to target.
For targets at ranges between hash marks
you can split the difference. For example, for
a target at 450 yards you should aim halfway
between the 400 and 500 yard hash marks.
We recommend that you establish a steady,
supported position in order to utilize the BDC.

UNDERSTANDING
THE WIND AND
BULLET DRIFT
109
Notice the 5mph wind hold dots aligned with
the BDC. Wind will cause the bullet to drift
left or right depending on wind direction.
Understanding wind is important, as even
a 2mph wind at a 90 degree angle to the
bullet’s path can cause the bullet to drift over
10” at 600 yards. The wind holds correspond
to the BDC ladder and represent how much
a 5mph wind will push the bullet at that
range. For a wind pushing left to right, use
the dots on the right side of the reticle. For a
wind pushing right to left, use the dots on the
left side of the reticle. You can use the dots
as a starting point in different conditions. For
example, if you have approximately a 2.5
mph wind, you would hold half-way to the
dot. If you have a 10 mph wind, you would
double the hold of the dot, and so on.
