The Holosun 507C-X3 updates the proven 507C platform with a refined X3 housing and the added visibility of a crisp green reticle, delivering a low-profile optic built for modern carry, duty use, and range performance. Using Holosun’s Multi-Reticle System, shooters can switch between a precise 2 MOA dot, a bold 32 MOA circle, or a combined reticle to match speed or precision needs. A forward-facing photodiode paired with Solar Failsafe automatically manages brightness as lighting changes, while manual controls with memory and lockout keep everything exactly where you want it. Powered by a side-loading CR1632 battery rated up to 100,000 hours and backed by Shake Awake, IP67 waterproofing, and 5000G vibration resistance, the 507C-X3 delivers dependable performance with standout visibility in a compact, carry-ready optic.
