Holosun - HS503GU Red Dot Sight - Multi Reticle

The HS503GU is a micro red dot optic equipped with a 65 MOA circle dot reticle with the option of switching to a 2MOA dot only. The “G” signifies that the battery is side mounted on the side of the optic. The “U” signifies a housing design that shrouds the windage and elevation turrets on two sides.

Use of an extremely efficient LED and optimized control system makes the device offer a theoretical operating time of up to 50,000 h on one battery at an average brightness setting.

The lenses made of special glass dedicated to the production of optics have been multi-layered with reflective coatings to ensure excellent transmission of visible light. This guarantees a bright, clear and interference-free image.

Multi Reticle System used in this model allows you to choose one of three reticle shapes: dot 2 MOA, circle 65 MOA and their combination. Depending on the type of weapon or the distance at which we take a shot, we can choose the type of reticle without losing zeroing.

The model is equipped with the Solar Failsafe system, which, in addition to saving batteries, introduces automatic brightness adjustment of the reticle. This solution is ideal for smooth transitions between open and closed spaces. It is also possible to deactivate the automatic mode - then we get 10 standard modes and 2 adapted to night vision, set manually by the user.

Shake Awake system used in the device is responsible for saving batteries. After the time programmed by the user, the collimator goes to sleep mode. To wake it up you only need a small movement of the weapon, on which it is mounted.
