Holosun 507C X3 Gold Circle Dot HS507C-X3-GD – Overview –
The Holosun HS507C-X3-GD-MRS brings a high-contrast gold reticle to the updated 507C-X3 platform, giving shooters faster visual pickup in bright light and against complex backgrounds. Built on the RMR footprint, it pairs a reinforced 7075-T6 aluminum housing with a slim, carry-ready profile for duty use, concealment, and range time. Holosun’s Multi-Reticle System lets users switch between a precise 2 MOA dot, a bold 32 MOA circle, or a combined reticle to match speed or precision needs. Automatic brightness from a forward-facing photodiode works with Solar Failsafe to keep the reticle dialed as conditions change, while manual controls with memory and lockout provide full control when needed. 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 HS507C-X3-GD-MRS delivers standout visibility without sacrificing reliability.
– TECH & FEATURES –
Solar Failsafe™
Shake Awake™
Multiple Reticle System
Super LED
Multilayer Reflective Glass
Solar Failsafe™
Solar Failsafe Technology is one of many innovations featured on solar-equipped Holosun optics. With Solar Failsafe, if your battery fails you always have a backup power source when natural or artificial light is available. Solar Failsafe is activated while in Auto Mode where reticle intensity is automatically adjusted based on the amount of light the solar cell receives. In brighter conditions you have a brighter reticle and in lower-light conditions the reticle will step down in intensity to match any lighting conditions. On models equipped with a super capacitor, it is possible to run the optic, indefinitely, in daytime and night conditions, by maintaining a charge through the Solar Failsafe System all without a battery.

The Holosun 507C X3 Gold Circle Dot HS507C-X3-GD is a premium open-reflex pistol optic designed to deliver exceptional visibility, durability, and versatility for modern shooters. Built on the proven 507C platform, this advanced optic combines Holosun’s cutting-edge technology with a distinctive gold reticle, offering enhanced contrast and fast target acquisition in a wide variety of lighting environments.
At the heart of the Holosun 507C X3 Gold Circle Dot HS507C-X3-GD is Holosun’s versatile Multi-Reticle System (MRS). This system allows users to switch between a precise 2 MOA gold dot, a bold 32 MOA circle, or a combined circle-dot reticle depending on the shooting scenario. The larger circle helps guide the eye to the center aiming point for extremely fast target acquisition at close range, while the standalone 2 MOA dot provides refined precision for more accurate shots at longer distances.
One of the standout features of this optic is its high-contrast gold LED reticle. The gold color offers a unique visual balance between red and green reticles, providing improved visibility against bright targets and complex backgrounds. This makes the optic particularly useful in outdoor environments or situations where traditional reticle colors may blend into the background.
The optic is powered by a CR1632 battery and can achieve up to 100,000 hours of runtime, thanks to Holosun’s ultra-efficient LED technology. Solar Failsafe technology uses ambient light to supplement power and automatically adjusts brightness based on surrounding conditions. In addition, Shake Awake™ technology automatically activates the reticle when motion is detected and powers it down when idle to conserve battery life.
Constructed from rugged 7075-T6 aluminum, the HS507C-X3-GD is built to withstand recoil, harsh environments, and daily carry use. The optic features IP67 waterproof protection, multi-coated glass for improved clarity, and a compact profile optimized for holster compatibility.
