HOL‑SUN HS510C Open-Frame Reflex Sight

Description

Engineered for elite operators and serious professionals, the HS510C combines an open-frame design with multi-reticle precision. Its rugged 6061‑T6 aluminum housing and titanium hood withstand recoil and environmental abuse, delivering battle-ready resilience.

At its core, the Multi-Reticle System (MRS) lets you toggle between a crisp 2 MOA dot, a 65 MOA circle, or both simultaneously—maximizing versatility for close-quarters speed or extended-range targeting. Backed by Holosun’s Solar Failsafe and Shake Awake™ tech, the HS510C offers up to 50,000 hours of battery life, with uninterrupted performance even if the CR2032 battery fails.

Engineered for zero-obstruction sight picture and rapid target acquisition, this optic features a generous 0.91″ × 1.26″ window, unlimited eye relief, parallax-free design, and 12 brightness settings (10 daylight, 2 NV compatible). The quick-detach mount supports absolute co-witness with iron sights, and the sight’s 0.5 MOA click adjustments support meticulous zeroing across ±50 MOA.

Weighing in at just 4.94 oz with dimensions of 3.3″×1.68″×1.78″, the HS510C adds elite optical capability without burden to any carbine or shotgun platform. 

Ideal for tactical duty, competition, or any serious operator seeking speed, precision, and no compromises
