The Primary Arms 507K GR X2 Green Dot Sight with ACSS Vulcan Reticle is a compact reflex optic engineered for shooters who demand fast target acquisition without the bulk of traditional tube-mounted red dot systems. Built on the proven Holosun K footprint, this green dot sight delivers the speed of a pistol red dot with the optical clarity and precision required for duty-grade performance.
This sight features a green ACSS Vulcan reticle—a ballistically optimized pattern specifically designed to reduce parallax error and enable precise holdovers at distance while maintaining an ultra-bright dot for close-quarters work. The green emitter improves contrast against most outdoor backgrounds and is easier on the eye during extended use compared to traditional red dots, reducing target fixation and fatigue.
The anodized black finish provides military-spec durability and corrosion resistance, while the compact form factor—just 3.75 by 2.5 inches in profile—eliminates snag points and maintains weapon ergonomics. Law enforcement officers carrying compact duty pistols and armed professionals will find the 507K platform to be a reliable choice for their tactical needs.
