Holosun HS510C Collimator Sight with 2 MOA Dot and 65 MOA Circle

Holosun HS510C - an open reflex collimator in the 'open window' form factor with a mounting on a Weaver/Picatinny rail, primarily designed for AR-15 and AK platforms of any caliber. The sighting system offers two reticle options: a 2 MOA dot for precise shots or a combination of a dot with a 65 MOA circle for quick target acquisition at close distances - this approach makes the collimator convenient for dynamic shooting competitions IPSC/USPSA and during hunting in dense areas.

The body is made of aviation aluminum T6061-T6, while the protective housing is made of titanium alloy, allowing the sight to withstand shock loads up to 1000 g and be mounted not only on rifles but also on smoothbore shotguns. The degree of protection ensures complete dust resistance and short-term immersion in water up to 1 m deep, which is relevant when hunting in rainy weather or under any field conditions.

Dual power supply is the main practical advantage of the model: the solar panel automatically maintains the charge of the CR2032 battery, serves as a brightness sensor for smooth brightness adjustment, and can independently power the sight under sufficient natural light. The adjustment increment is 1/2 MOA (1.5 cm at 100 m) with a range of 50/50 MOA vertically and horizontally, allowing for precise zeroing of the collimator to specific firearms without unnecessary manipulations. The quick-release mount installs on the rail without tools, and the optical axis height of 36 mm ensures comfortable use with standard AR-15 stocks.

HS510C is suitable for practical shooters who value reliability and autonomy of equipment, hunters for game and birds, as well as carbine owners looking for a durable collimator with minimal maintenance and convenient brightness control without unnecessary buttons.
