The Holosun HS510C Reflex Sight is a high-performance open reflex optic designed for rifles, carbines, and PCC platforms. Known for its wide field of view, lightweight design, and advanced electronic features, the HS510C provides fast target acquisition and dependable performance for tactical, competition, and hunting applications.

This optic incorporates Holosun’s Multi-Reticle System (MRS), allowing users to switch between a 2 MOA dot, a 65 MOA circle, or a circle-dot combination depending on shooting needs. The sight is powered by a CR2032 battery with up to 50,000 hours of battery life, supported by Solar Failsafe technology that provides backup power using ambient light.

The HS510C also features Shake Awake technology, which automatically powers down the optic when idle and instantly reactivates it when motion is detected, extending battery life and ensuring the sight is always ready.

With its durable 6061-T6 aluminum housing and protective titanium hood, integrated quick-detach mount, and large viewing window, the HS510C is built to perform reliably in demanding shooting environments.
