Description
The Holosun HS507C-X3 is the latest evolution of Holosun's most popular full-size pistol optic, updating the proven 507C with a reinforced 7075-T6 aluminum housing and a refined, low-profile design. The open emitter delivers a wide, unobstructed sight picture, and Holosun's Multi-Reticle System lets you choose a 2 MOA dot for precision, a 32 MOA circle for speed, or the combined circle-dot – in red, green, or gold using the selector above.
New for the X3, a forward-facing light sensor works alongside Solar Failsafe to help manage brightness as conditions change, while Shake Awake, Lock Mode, and last-setting memory keep the optic ready and your settings locked in. A side-loading CR1632 battery delivers up to 100,000 hours of runtime and swaps without pulling the optic from the slide. The housing is IP67 waterproof and 5000G rated, and the industry-standard RMR footprint direct-mounts to a wide range of optics-ready pistols.
