The Holosun HS510C Red Dot Sight has been built with durability and versatility in mind. A rugged aluminium housing with open frame provides a large sight picture with a wide field of view, minimising obstruction of vision. The optics are protected by a titanium shock resistant protective hood enabling it to withstand drops, knocks and rigorous use as well as being IP67 rated making it waterproof up to 1m. No matter your operating conditions or tactical situation, the battle tested HS510C is proven to be super reliable even when mounted on high-powered rifles.

Holosun are leading the way in red dot sight technology and innovative shooting optics. The Holosun HS510C features Shake Awake technology which ensures your red dot sight turns on instantly upon pickup or draw while conserving battery power when motionless.

A Dual Power Supply incorporates a high-capacity CR2032 battery and Advanced Super Solar Technology, intelligently switching between battery and solar power as needed. The solar power supply also acts as a Power Failover providing backup power in the unlikely event the battery fails. The highly efficient solar cell enables the Holosun Red Dot Sight to even operate under low-light conditions, ensuring the Holosun HS510C will never let you down when you need it most.

A Multi-Reticle System gives you a choice of 3 reticle options; a 2 MOA Red Dot, 65 MOA Circle or Dot In Circle. The reticles are Illuminated in RED and you have 10 Levels of Brightness and 2 Levels of Night Vision Compatible Modes, which you can quickly set according to your preference. The same red LED is used for all 3 reticles so there is no need to re-zero between reticle changes. In Auto Mode the brightness of the reticle automatically adjusts to the ambient light ensuring the reticle is optimally visible under all light conditions.
