HIGH PERFORMANCE MULTIPURPOSE REFLEX SIGHT
CHAPTER I
1.1. Presentation
Aimpoint’s Reflex Sights are rugged precision electronic optical red dot sights developed for
military and law enforcement applications.
Aimpoint sights are designed for the ”two eyes open” method of aiming, 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.

CHAPTER II
OPERATION UNDER NORMAL CONDITIONS
2.1. ASSEMBLY AND PREPARATION FOR USE
WARNING: Insure the weapon is unloaded and the safety selector is in the ”safe” position
before attempting to install, remove or perform maintenance on the sight.

so could result in water leakage into the battery compartment.
c) Install battery cap by turning clockwise until snug. Hand tighten only. Using tools could
damage equipment.
d) Verify that red dot is present by turning the rotary switch clockwise.
