Description
The Holosun HS510C-FDE-R delivers the speed and wide field of view of Holosun's popular open reflex rifle optic in a durable flat dark earth finish. Its large viewing window, Red Multi-Reticle System, Solar Failsafe, and Shake Awake provide fast target acquisition and dependable performance on carbines, PCCs, and shotguns.
The Multi-Reticle System switches between a 2 MOA dot, a 65 MOA circle, or a combined circle-dot reticle from the same 650nm red Super LED, so no re-zeroing is required when you change reticles. An aluminum housing with a reinforced titanium hood, IP67 waterproofing, and an included absolute co-witness quick-detach mount make it a rugged, versatile rifle optic, while Solar Failsafe and Shake Awake keep it powered and ready for up to 50,000 hours on a single side-loading CR2032.
