Description
The Holosun HS510C is a rugged, full-featured open reflex sight built for rifles, carbines, PCCs, and shotguns. Combining a lightweight aluminum housing with a titanium-alloy protective hood, the HS510C delivers a wide, unobstructed sight picture while standing up to the rigors of hard use in the field, on duty, or in competition. It ships complete with a quick-detach absolute co-witness mount, putting the dot right in line with your iron sights for instant compatibility with a wide range of AR-pattern rifles and carbines.
Wide-Open Sight Picture
With an objective window measuring approximately 0.91″ x 1.26″ and a weight of about 4.94 ounces, the HS510C offers an expansive field of view that speeds up target acquisition and helps you maintain situational awareness with both eyes open. The titanium hood surrounds the lens for added impact protection without closing in the sight picture, keeping the open-reflex design fast and intuitive under stress.
Multi-Reticle System (MRS)
At the core of the HS510C is Holosun’s Multi-Reticle System, giving shooters the choice of three reticle configurations: a precise 2 MOA dot for accurate, deliberate shot placement at distance, a fast-acquisition 65 MOA circle for close-quarters engagements, or a combined circle-dot reticle that blends speed and precision. Because all three options come from the same emitter, switching between them requires no re-zeroing, so your point of impact holds true regardless of which reticle you choose.
Solar Failsafe Technology
The HS510C includes Holosun’s Solar Failsafe system, which uses an onboard solar panel to harvest ambient light and help power the optic while automatically adjusting brightness in changing light conditions. This gives you a dependable backup power source, so a depleted battery in the field doesn’t mean a dead optic.
