Holosun 507C X3 Green Dot Sight, 2 MOA Dot & 32 MOA Circle

Holosun 507C X3 Green Dot Sight Features and Performance

The Holosun 507C X3 green dot sight is built for shooters who want a fast, clear, and dependable open pistol reflex optic with a familiar RMR footprint. Also commonly searched as the HS507C or 507C, this optic gives optic-ready pistols, competition handguns, PCCs, rifles, and shotgun setups a clean aiming upgrade without making the firearm feel overcomplicated.

The green Multi-Reticle System lets you select a 2 MOA dot, 32 MOA circle, or combined circle-dot reticle. The dot gives you a precise aiming point for controlled shots, while the circle or circle-dot view helps with faster reticle pickup at close range. With 1x magnification, a parallax-free design, unlimited eye relief, and multi-coated glass, the Holosun 507C X3 is built for fast, natural target acquisition from different shooting positions.

The feature set is what makes the Holosun 507C a practical everyday optic. Solar Failsafe adds an additional power source in changing light, while Shake Awake helps conserve battery life by powering the reticle down during inactivity and bringing it back when movement is detected. The side-loading CR1632 battery tray allows battery changes without removing the optic from the firearm, helping preserve zero and keeping maintenance simple.

The Holosun 507C X3 green dot includes 8 daylight brightness settings, 4 night-vision settings, manual brightness control, memory function, auto-off, and lockout mode. Battery life is rated up to 50,000 hours on setting 6, giving the optic a strong balance of performance and low-maintenance ownership.

Build quality matters on an optic that may live on a carry pistol, competition handgun, rifle, PCC, or shotgun. This model uses a black anodized 7075-T6 aluminum housing with 1 MOA click adjustments, ±50 MOA windage and elevation travel, IP67 submersion rating, and 5000G vibration rating. The optic weighs 1.55 oz and measures 1.78" × 1.31" × 1.1", with a 0.91" × 0.67" window.

Choose the Holosun 507C X3 green dot sight when you want an RMR-footprint optic with a green selectable reticle, side-loading battery, solar backup, Shake Awake, durable housing, and a clear pistol-ready sight picture.
