Tactical Gear Redefined™
This rugged and reliable sight provides assured accuracy from a 4X fixed
magnification reticle,graduated to 600 meters. It features three reticle
modes; non-illuminated black, illuminated green and illuminated red, with
each illuminated mode offering 5 brightness settings. Anodized aluminum
construction with a nitrogen filled body ensures optimal performance in the
most extreme conditions.

To mount on M1913/Weaver accessory rail:
Loosen locking bolt using coin or screwdriver
■ Mount on rail, and secure by tightening locking bolt

illuminated green or red brightness settings 1 – 5 by rotating switch left
or right. Settings are colored green or red to correspond with reticle
pattern color.
■ Adjust windage and elevation by removing turret covers and using coin
or screwdriver – counterclockwise: move impact left/up – clockwise: move
impact right/down.

Battery manufacturers warn against mixing new and used batteries or different brand batteries
together as this may increase the risk of leakage, fire or explosion. Do not, puncture, short-circuit,
disassemble or heat batteries above 212°F (100°C). Do not recharge the batteries unless they are
specifically designed as rechargeable batteries and then only in accordance with manufacturer’s
Lithium Batteries: Industry wide there have been reported incidents of off-brand Lithium batteries
exploding or catching fire creating serious consequences. Sig Sauer, Inc. includes batteries from
Duracell® and other well-known battery manufacturers with its products, and strongly urges you to
only purchase replacement batteries from Duracell®, or other well-known battery manufacturers like
Panasonic® and Rayovac®. These batteries are designed for use in high performance, high-drain
devices, and their designs incorporate fault and heat protection for added safety. Use of inferior
batteries may cause an explosion or fire, creating risk of damage to your device that will void the SIG
Sauer Inc. warranty, cause damage to other property, and potentially serious injury or death.

The CP4 reticle is used to determine the
range of a target of known size. The example
below shows an 18” wide target bracketed
between the first two shorter vertical stadia
lines of the reticle. The distance between
these two stadia lines is 18” at 100 yds as
stated in diagram XX (which will be the
reticle diagram with dimensions).

The lower range scales is for bracketing a
32” tall target.
If you reference the MOA chart you will
see that the distance between the short
line at the top of the target and the bottom
horizontal line is 16 MOA.
The formula is then: 32 (height of the target)
÷16 (MOA from chart) x 100 = 200 yds.
The CP4 reticle can be used for aiming even
though it is not a bullet drop design.
To use the reticle for aiming you must know
several data points. First, you must know
the bullet drop of your specific cartridge.
For example let’s use M855 5.56 NATO. Zero
the firearm at 100 yds. Move to 200 yards
and fire a three to five shot group. Measure
the distance between your point of aim
and center of the group. Let’s say it drops
4.0”. You must then have a reference of a known measurement on the reticle to use
as an aiming point. In this case the center dot of the reticle measures 1.8” at 100 yds.
So at 200 yds it will be 3.6” (1.8” x 2=3.6”) which is as close to a 4.0” reference point as
you will get with the reticle. Hold over the height of the dot from your intended point of
impact at 200.
At 300 yds the M855 will drop approx. 15.2”. The measurement of reference “J” of the
reticle is 10.1” at 100 yds, so at 300 yds it is 30.0”. Use the halfway point of the vertical
stadia line as a hold point on the target at 300 yds.
