PRESENTATION

Aimpoint® red dot sights are designed for the ”two eyes open” method which greatly enhances situational
awareness and target acquisition. Thanks to the optical design the red dot follows the movement of the user’s eye while remaining fixed on target, eliminating any need for centering.

OPERATION

WARNING: Ensure the weapon is not loaded and the safety selector is in the ”safe” position before attempting to install, remove or perform maintenance.

Install or replace battery

  • Unscrew and remove the battery cap (4).
  • If replacing battery (5), remove depleted battery from the battery compartment by carefully pressing on an edge as shown in Fig 2.

CAUTION: Take care not to damage the battery or the battery compartment. Do not use sharp tools (e.g. a
knife) to remove the battery.

  • Insert battery (5) with the positive end (+) toward the battery cap (4) as seen in Fig. 1.

CAUTION: Check that the o-ring on the battery cap (4) is in position and in good condition to ensure there is no water leakage into the battery compartment.

  • Tighten the battery cap (4). When resistance is encountered, proceed to tighten until fully tightened.

NOTE: For long term storage of the sight, remove the battery.

Turn ON / OFF and adjust red dot intensity

  • Press any of the push-buttons (1) to turn the sight ON.

NOTE: The sight will always turn ON at setting 7 of 10.

NOTE: Intensity setting 1 – 4 are intended for use with NVD and intensity setting 5 – 10 for use in daylight.

Install the sight

If the sight is equipped with one of the mounts (9A / 9B) shown in Fig. 1, follow the described procedure. For
installation with other mounts, see accompanying instruction.

  • Loosen the screw (12) using the Torx T10 tool (3), and clamp the locking bar (11) around the Picatinny rail.
  • With the recoil stop positioned in a groove of the Picatinny rail, push the sight forward (towards muzzle) and tighten the screw using the tool. See Fig. 3.
  • Tighten the screw until a light resistance is encountered. Proceed with another 1/4 to 1/2 turn until fully tightened (3 Nm / 2.2 ft·lb).

CAUTION: Do not overtighten.

Zeroing

CAUTION: Do not continue to adjust windage and elevation screws (6) (7) if you encounter resistance.

  • Adjust the intensity to a comfortable setting for the red dot to contrast clearly against the target.
  • Fire at least three shots to evaluate points of impact.
  • Use the Torx T10 tool (3) to turn the adjustment screws.
  • Windage adjustments (see Fig. 4):
    • Turn windage adjustment screw (6) counterclockwise to move point of impact to the right (R).
    • Turn windage screw (6) clockwise to move point of impact to the left.
  • Elevation adjustments (see Fig. 5):
    • Turn elevation adjustment screw (7) counterclockwise to move point of impact up (U).
    • Turn elevation adjustment screw (7) clockwise to move point of impact down.
  • Confirm zeroing by firing at least three shots at zeroing target and repeat zeroing procedure if required.
  • Ensure the sight is securely installed on the weapon and retighten the screw (12) if necessary.

NOTE: Each click of the adjustment screws corresponds to movement of point of impact of approximately 14 mm at 100 m / 0.5 in at 100 yds / 0.5 MOA per click.

EXTREME CONDITIONS

  • Extreme heat (moist or dry): no special procedures required.
  • Extreme cold: extreme cold might shorten battery life.
  • Salt air: no special procedures required.
  • Sea spray, water, mud and snow: ensure the battery cap is tightened before exposing the sight to sea spray, mud, snow or before submerging the sight in water. Clean lenses with lens paper/cloth and wipe the sight dry as soon as possible after exposure to water, sea spray, mud or snow.
  • Dust storms and sand storms: no special procedures required.
  • High altitudes: no special procedures required.

CAUTION: Never clean the lenses with fingers. Use lens paper/cloth. If lens paper/cloth is not available:

  • To clear away debris (sand, grass etc.): blow away the dirt or rinse with clear water.
  • To clean lenses: fog the lenses or rinse with clear water and clean them with a soft piece of cloth.

TROUBLESHOOTING

The red dot does not appear or has disappeared

Make sure contact surfaces in the battery compartment are clean and verify that a working battery (CR2032) is installed correctly according to 2.1. If the sight is malfunctioning, notify local dealer/armourer.

The sight is impossible to zero

If an adjustment screw (6) or (7) is at its limit, check the alignment of mount and barrel. If point of impact is moving, check if the sight is securely installed on the weapon and check weapon rail (or carry handle) stability.

MOUNT INSTALLATION

To avoid damage to the sight and for proper assembly of the mount base (9) onto the sight, the original screws (10) must be tightened by hand and with the Torx T10 tool (3).

  • Place the sight upside down in your hand.
  • Press the mount base (9) against the sight and verify there is no gap.
  • Apply thread locking fluid to the threads and install the screws (10).
  • Tighten the screws (10) in a crosswise pattern. Tighten until resistance is encountered. Proceed with another 1/4 to 1/2 turn until fully tightened (1.35 Nm / 1.0 ft·lb).

CAUTION: Do not overtighten.
