1.1 Presentation
Aimpoint CompM4s Reflex Sight is a rugged precision red dot Sight developed
mainly for military and law enforcement applications.
Aimpoint red dot sights are designed for the ”two eyes open” method of
sighting, which greatly enhances situational awareness and target acquisition
speed. Thanks to the parallax-free design, the dot follows the movement of the
user’s eye while remaining fixed on the target, eliminating any need for centering. Further, the Sight allows for unlimited eye-relief and is compatible with 1st ,
2nd and 3rd generation night vision devices.
The CompM4s Sight is using a AA size battery, which together with the extremely low power consumption gives an unequalled battery life.
The CompM4s combines the superior accuracy and ease of use of the wellknown CompM2 model with significantly longer battery life and increased
ruggedness through reinforced design.
The Sight is provided with a torque knob, Quick Release (QRP2) mount.
The Sight has a Spacer system that gives optimal height of the line of sight
(optical axis) on different weapons.
Over 8 years of continuous (day and night) use at pos 12 of 16 and over 3 years at pos 13 of 16.

Submersible to 45 m (150 ft)
2.1.2 Installing Sight on the weapon
The CompM4s Sight is designed for installation on most types of weapons,
which have a MIL-Std 1913 Picatinny Rail.
Depending on type of weapon, the optical line of sight (the centre of the lens
system) may have different optimal height over the mounting rail. The height
of the optical axis of the Sight alone (without Spacer) is 30 mm (1.2”). With
the Spacer (9) mounted, the height of the optical axis is increased by 9 mm
(0.35”).
a) Assemble the Sight with the Mount QRP2 (8) by means of the two short
screws (6) and the Allen Wrench (14). Tighten firmly. Some thread glue
(e.g. a “light” Loctite) could be used on the screw threads. See Fig A below.

aa) Assemble the Sight with the Mount QRP2 (8) and the Spacer (9) by
means of the two long screws (7) and the Allen Wrench (14). Tighten
firmly. Some thread glue (e.g. a “light” Loctite) could be used on the
screw threads. See Fig B below.
b) Install the Sight to the weapon rail by using the Knob, Torque (12).
Ensure that the Sight is correctly positioned and that the recoil stop
fits into a groove on the Picatinny Rail. To ensure that Sight is secure,
tighten Knob, Torque (12) until it snaps twice.
c) When using Lens Covers, ensure that they are correctly positioned and
can easily be opened/removed.
d) Finally, make sure that the Knob, Torque (12) is firmly tightened around
the weapon rail.
e) Complete zeroing according to 2.2.1.
2.1 ASSEMBLY AND PREPARATION FOR USE
WARNING: Ensure the weapon is unloaded and the safety selector is in the
”safe” position before attempting to install, remove or perform maintenance on
the sight.
2.1.1 Installing Battery
a)Remove Cap Battery (4) by turning it counter clockwise.
b) Insert a AA-size battery with negative (-) end toward cap.
Caution while replacing battery (not necessary when the sight is new).
Before installing Cap Battery, inspect that the O-ring is present and not damaged.
Failure to do so could result in water leakage into the battery compartment.

2.1.3 Lens Covers
In order to preclude the loss of the Lens Covers when removed from the
optical path of the Sight, the Lens Covers should be removed downwards.
The rubber string will then attach around the Sight and mount.
2.2 OPERATING PROCEDURES
2.2.1 Zeroing
The Sight is delivered in a centered position. Normally this means that only
small adjustments are necessary, providing that the weapon rail (Picatinny
Rail) or carrying handle is properly aligned.
CAUTION: Do not continue to adjust windage and elevation mechanisms if
you encounter resistance.
The elevation adjustment screw is located on top of the sight, while the
windage screw is located on the right side.
a)Open (remove) front and rear Lens Covers (13).
b)Turn the Knob Switch (10) clockwise until the red dot has a sufficient intensity to contrast against the target.
c)Remove the the Caps Adjustment (1) for windage and elevation.
NOTE: Each click of the Screw Adjustment (11) corresponds to a 16 mm
movement of the point of impact at 100 meters, (4 mm at 25 meters and 32
mm at 200 meters or 1⁄2” at 80 yds).
d) Insert adjustment tool (coin, screwdriver, knife) or cartridge casing in
adjustment screw slot and turn as follows:
•To move the point of impact to the right, turn windage adjustment screw counter clockwise
• To move the point of impact to the left, turn windage adjustment screw clockwise
•To move the point of impact up, turn elevation adjustment screw counter clockwise.
•To move the point of impact down, turn elevation adjustment screw
clockwise.
e)Confirm zeroing by firing at least three shots at a zeroing target. Check points of impact on zeroing target to confirm accuracy and repeat above procedure if required.
f) After initial firing, ensure that the Mount and Sight are secure.
g)Turn Knob Switch (10) to OFF position (counter clockwise).
h)Close front and rear Lens Covers.

d)Sea spray, water, mud and snow. Ensure that Cap Battery (4) and the two
Caps Adjustment (1) are tightened before exposing the sight to sea spray,
mud, snow or before immersing the sight in water. Hand tighten only. Keep
Lens Covers closed when sight is not being used. Clean lenses with lens
paper/cloth and wipe the sight dry as soon as possible after exposure to water,
sea spray, mud or snow.
e)Dust storms and sand storms. Keep Lens Covers closed when sight is not
being used.
f) High altitudes. No special procedures required.
a)This Sight does not require any particular maintenance while used under
normal conditions.
b)Under severe weather conditions please refer to chapter III.
c)Keep Lens Covers closed whenever the sight is not in use.
d)Warehouse storage: Remove battery and allow lens surfaces to dry completely
(if wet) before closing the lens covers.
e) To clean lenses refer to CAUTION in chapter III.
