Aimpoint MpS3 MGM mount

Aimpoint MpS3 MGM mount
CHAPTER I
1.1 Presentation
The Aimpoint MPS3 with the MGM mount is a rugged, passive, red dot sight
developed mainly for use in demanding applications on medium or heavy
vehicle-mounted weapons under all light conditions. Its simplicity of use,
based upon the “One Function Principle” allows the user to concentrate on
the target and operate the MPS3 and MGM even with thick winter gloves in
the dark. The MPS3 with MGM combines the superior accuracy and ease of
use of the well-known Aimpoint sight models with significantly longer battery
life and increased ruggedness through reinforced design.
Aimpoint red dot sights are designed for the “two eyes open” method of
sighting, which greatly enhances situational awareness and target acquisition
speed. These sights also feature unlimited eye-relief and are compatible
with all generations of night vision devices. The MPS3 features extremely
low power usage, and with the ability to use either alkaline or lithium AA size
batteries provides an unequalled battery lifetime.
The MGM mount is made for use in MIL STD 1913 Picatinny Rail applications
and has integrated windage and elevation adjustments for zeroing of the
MPS3 as well as an integrated, 3-step ballistic compensation adjustment.

OPERATION UNDER NORMAL CONDITIONS
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 Battery Cap (4) by turning it counter clockwise.
b) Insert a AA-size battery with negative (-) end toward Cap (4).
Caution while replacing battery (not necessary the first time the sight is
used) Before installing Battery Cap, inspect that the O-ring is present and
not damaged. Failure to do so could result in water leakage into the battery
compartment.
c)
Install Battery Cap (4) by turning it clockwise until snug. Hand tighten only. Using tools could damage equipment.
d)
Verify that red dot is present by turning the Switch Knob (3) clockwise.
2.1.2 Installing Sight on the weapon
The MPS3 with MGM mount is designed for installation on most types of
medium or heavy support weapons, which have a MIL-STD 1913 Picatinny Rail.
First, remove the Recoil Stop (2) by screwing it counter clockwise. Then loosen
the two Screws (1) for mounting to the Picatinny Rail.

Picatinny Rail for mounting of accessories
Assemble the MPS3 with MGM mount to the weapon Picatinny Rail by sliding
the unit onto the Rail, either from the front or from the rear end. Try to find a
suitable position of the Sight unit on the Rail. Then insert the Recoil Stop (2).
The Recoil Stop (2) shall fit into one of the grooves of the Rail.
Firmly tighten the two Screws (1) and finally tighten the Recoil Stop (2). The
Screws (1) and the Recoil Stop (2) shall be tightened with a hex key, size 5 mm.
After firing several rounds, check that the MGM mount is still securely tightened
to the weapon’s accessory rail. Retighten the Screws (1) if necessary.
2.2 OPERATING PROCEDURES
2.2.1 Zeroing
The MPS3 with MGM mount is delivered in a centered position. Normally
this means that only small adjustments in elevation (5) and windage (7)
are necessary, providing that the Picatinny Rail on the weapon is properly
aligned.
d) Confirm zeroing by firing at least three shots at the zeroing target.
Repeat above procedure if required.
e) After initial firing, ensure that the MGM mount and MPS3 are secure.
f) Turn Switch Knob (3) to OFF position (counter clockwise).
Fig. A Fig. B Fig. C
Zeroing should be done at the shortest distance decided for the Ballistic
Compensation Lever Arm (6), e.g. 200 meters (200 yds) if the ballistic
compensation is decided to be set for 200 – 800 – 1200 meters
(200 – 800 – 1200 yds).
The Elevation Adjustment Screw (5) is located rear on top of the MGM
mount, while the Windage Adjustment Screw (7) is located on the right side.
a)
b) Turn the Switch Knob (3) clockwise until the red dot has a sufficient intensity to contrast against the target.
Turn the Ballistic Compensation Lever Arm (6) to the “shorter distance” position. The Arm will then be directed horizontally backward (to the gunner). See fig. A.
NOTE: Each click of the adjustment screws corresponds to a 50 mm
movement of the point of impact at 100 meters (2” at 100 yds), 100 mm at
200 meters (4” at 200 yds).
CAUTION: Do not continue to adjust windage and elevation mechanisms if
you encounter resistance.
c) Insert adjustment tool (screwdriver or knife) in adjustment screw slot and
turn as follows:
• To move the point of impact to the right, turn windage adjustment screw (7) 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 (5) clockwise.
• To move the point of impact down, turn elevation adjustment screw counter clockwise.
e) Dust storms and sand storms. Try to keep front end rear lenses protected
with lens covers..
f) High altitudes. No special procedures required.
CAUTION: The lenses should only be cleaned with lens paper/cloth and never
with fingers. If no lens paper/cloth is available:
- First, clear away debris (sand, grass etc): blow away the dirt.
- To clean lenses: mist up the lenses and dry them with a clean and soft piece of cloth.
CHAPTER IV
Trouble shooting procedures
2.2.2 Operation under normal conditions
a) Turn the Switch Knob (3) clockwise until the red dot has a sufficient intensity
to contrast against the target.
b) Turn the Ballistic Compensation Lever Arm (6) to the position that
corresponds to the target distance according to figures A, B or C.
Arm position Target distance meters (yds)
A 200
B 800
C 1200
(provided zeroing has been done at 200 meters)
CHAPTER III
Operation under extreme conditions
a) Extreme heat (moist or dry). No special procedures required.
b) Extreme cold. Extreme cold might shorten battery life.
c) Salt air. No special procedures required.
d) Sea spray, water, mud and snow. Ensure that Battery Cap (4) is tight
before exposing the MPS3 to sea spray, mud, snow or before immersing the
sight in water. Hand-tighten only. After exposure to water, sea spray, mud
or snow, wash the entire unit with fresh water only. Clean lenses with lens
paper/cloth and wipe the MPS3 dry as soon as possible.
