Product Description The Primary Arms Holosun HS507C-X2 Red Dot Sight with ACSS Vulcan Reticle is a next-generation pistol optic engineered for shooters who demand reliability, speed, and precision. After rigorous field testing, this optic earned a Silver-tier rating from the National Tactical Officers Association. Featuring the revolutionary, patent-pending ACSS Vulcan reticle, the HS507C-X2 presents a large outer reference circle that naturally guides the eye to the 10 MOA center chevron, dramatically improving sight acquisition for shooters new to slide-mounted optics. When the chevron is properly centered in the window, the outer circle disappears entirely - eliminating the guesswork. The outer circle can also be deactivated for extended battery life. Built from 7075-T6 aluminum with a black hardcoat anodized finish and fully multicoated glass, this optic is designed for long-term durability in demanding conditions. Solar failsafe and Shake Awake technology keep the sight operational without draining the battery, while the CR1632 battery tray allows for easy battery changes without removing the optic from the pistol. Versatile enough for handguns, rifles, pistol-caliber carbines, and shotguns, and backed by Holosun&';s Limited Lifetime Warranty, the HS507C-X2 ACSS is a premium optic at a competitive price point. Note: Does not include Picatinny mount.
