Holosun HS510C Red Dot Sight Red Dot

The Holosun HS510C is an open reflex collimator sight built to deliver a fast, unobstructed sight picture for long guns—without adding bulk. Its wide 0.91 x 1.26 in window speeds target acquisition while keeping your peripheral vision clear, making transitions and follow-up shots noticeably faster.

Designed around hard use, the HS510C pairs an aluminum housing with a titanium hood to resist impact and maintain zero under recoil. Precise 0.5 MOA click adjustments and a generous ±50 MOA windage/elevation travel range let you dial in confidently, whether you’re zeroing at the range or refining holds for your setup. The MAO surface finish adds durability, and the compact 3.3 x 1.68 x 1.78 in footprint keeps your rifle or PCC balanced at just 4.94 oz.

This Holosun red dot sight is at home on carbines, PCCs, and shotguns where speed matters—competition stages, defensive setups, or demanding training days. With IP67 submersion resistance and a working temperature range of -30℃ to 60℃ (storage down to -40℃), it’s engineered to keep running in rain, dust, and cold-weather conditions.

Holosun’s HS510C is widely adopted for its rugged design and repeatable adjustments, backed by a platform known for innovation in rifle optics.
