The Holosun HE507C-GR-X2-ACSS Reflex Green Dot Sight is a rugged, open-emitter pistol optic featuring the ACSS® Vulcan™ reticle, engineered to improve dot acquisition speed and shooting consistency. Designed in collaboration with Primary Arms, the ACSS Vulcan system uses a precise center chevron for accurate aiming, paired with a large outer reference ring that remains invisible during proper sight alignment but guides the shooter back on target when off-axis. Built with a durable 7075-T6 aluminum housing, this optic incorporates Solar Failsafe™, Shake Awake®, and a side-load battery tray for easy maintenance. The RMR-pattern footprint ensures broad compatibility with optics-ready pistol slides.
