Holosun Red Dot HS503GU collimator

TheHolosun HS503GU is a compact collimator sight with a closed design that features the Shake Awake battery saving system, the Multi Reticle system for changing the aiming mark and two mounting bases.

The collimator is designed for the use of long guns including AR15 carbines, semi-automatic rifles.

Lightweight construction

The body of the sight is made of 6061-T6 aluminum by precision milling. The unit has a lightweight and durable design weighing only 150 g (with high mount). The Holosun HS503GU provides "stable zero holding", has no parallax error, and its optics provide unlimited eye relief, making it suitable for use on sporting rifles, AR carbines and hunting weapons.

Optics

The Holosun S503GU uses lenses coated with multi-layer anti-reflective coatings, which provide high light transmission and a clear and sharp image free of parallax error.

Electronic system

Thecontrol system and diode are resistant to shock (1000 G), weapon recoil and weather conditions, making the device work efficiently and stably on hunting and sporting weapons.

Variable aiming point

Thanks to the Multi Reticle System, the user can change the aiming mark. You can choose between a classic 2 MOA dot and a 65 MOA circle. Such functionality makes the collimator great for hunting, as well as for sport and tactical shooting. The LED displays the aiming mark in red color. All aiming marks are emitted by a single diode, so when you change the reticle you do not lose zero. The control system and the diode are resistant to shock, weapon recoil and weather conditions, so the device works efficiently and stably even in difficult hunting conditions.

Battery saving system

The device'simpressive runtime of up to 50,000 hours is due to the Shake Awake system, which automatically turns off the LED when there is no movement, and the device goes into sleep mode. Re-activating the aiming mark requires only moving the weapon. The user can independently define the time after which the sleep mode is activated.

Convenient battery installation

An element that many shooters pay a lot of attention to is the way the battery is mounted. In the Holosun HS503GU, the battery is mounted on the side of the sight, under the nut on the right side of the body. Such functionality allows you to change the battery without having to remove the collimator from the weapon, as is the case with models with the battery located on the underside.

Two mounts

The set includes two mounts for the Picatinny/Weaver rail: a high one (1/3 co-witness) intended mainly for carbines and a low one recommended for shotguns and rifles of the AK family.
