Holosun HS510C Open Reflex Red Dot Sight (2 MOA Dot / 65 MOA Circle, Solar Failsafe, QD Mount)
The Holosun HS510C is a 1x open reflex sight with a large viewing window and Holosun’s Multi-Reticle System (MRS), offering a selectable 2 MOA dot, 65 MOA circle, or combined circle-dot reticle. A 650nm red LED emitter and 12 brightness settings (10 daylight / 2 night vision compatible) provide adaptable reticle visibility.
Solar Failsafe and Shake Awake support efficient power management, while the side-mounted CR2032 battery tray allows battery changes without removing the optic. The aluminum housing with a titanium protective hood and an integrated quick-detach Picatinny co-witness mount (1.41" dot height) round out the HS510C’s compact, carbine-ready setup.
