Holosun - Combo Kit 510C Collimator and HM3X Magnifier - Quick-Detach Mount - 3x Magnification - Absolute Co-witness - HS510C+HM3X

The Combo Kit featuring the HS510C red dot sight and HM3X magnifier is a complete aiming system designed for short- and medium-range shooting. The combination of an open-sight design with a magnification module allows for instant adaptation of the weapon to changing conditions.

HS510C Red Dot Sight – Advanced Optics and MRS System

The Holosun HS510C is an open-sight red dot sight utilizing the Open Reflex system, characterized by minimized parallax. The device is equipped with the MRS system, which allows you to choose one of three reticles: a 2 MOA dot, a 65 MOA circle, or a combination of both. The reticle is projected by a red LED, and multi-layer optical coatings ensure image clarity.

Hybrid Power Supply and Shake Awake Technology

The sight uses a dual power source—a built-in solar cell that supplements the CR2032 battery. Utilizing solar energy allows the device to operate without drawing power from the battery under adequate lighting conditions.

Energy efficiency is ensured by the Shake Awake system, which puts the LED to sleep during inactivity and wakes it up upon detecting motion, restoring the last brightness setting. This solution provides a battery life of up to 50,000 hours. Users have 12 brightness modes at their disposal, including 10 daytime modes and 2 modes dedicated for use with night vision.

Durability and QD Mounting of the Red Dot Sight

The collimator’s body is made of aluminum reinforced with an additional coating of durable titanium. The design meets the IP67 waterproofing standard and is vibration-resistant up to 1000 G. The device features an integrated Picatinny rail mount with a QD lever, allowing for quick attachment and removal without tools. The optical axis height is 36 mm, which complies with the Absolute Cowitness standard.

HM3X Magnifier – Flexibility at Medium Range

The HM3X magnifier offers a fixed 3x magnification, significantly facilitating target identification at longer ranges. The aluminum housing is nitrogen-filled, which effectively prevents the lenses inside the body from fogging during sudden temperature changes.

The device provides 75% light transmission and a 7° field of view. The 70 mm eye relief ensures comfortable use, and the +/- 3 diopter adjustment allows the focus to be tailored to the shooter’s vision.

Flip-to-side system and compatibility with red dot sights

The magnifier is mounted on a Picatinny QD mount with a flip-to-side function. This allows the magnifier to be instantly flipped to the side when not in use, and to return to aiming without magnification, using the red dot sight alone. Thanks to the included spacer rings, the HM3X is compatible with red dot sights featuring Absolute Cowitness and Lower 1/3 optical axis heights.
