The Holosun 507 Red Performance Reticle Extra‑Large Open Lens Shake Awake 7075 Aluminum Miniature Pistol Reflex Sight is a rapid‑acquisition pistol optic designed for competition, defensive, and range use. It features Holosun’s Performance Reticle with a bright red 2 MOA dot paired with an 8 MOA circle, giving a fast, intuitive aiming point that’s easy to pick up on target. The extra‑large open lens enhances situational awareness and sight picture speed while still offering unlimited eye relief and parallax‑free performance at typical handgun engagement distances. Built from rugged 7075‑T6 aluminum with a hard‑anodized finish, it includes Shake Awake technology to conserve battery life and deliver thousands of hours of runtime on a single CR1632 battery. The sight also offers precision windage and elevation adjustment with 1 MOA clicks and is rated IP67 for waterproof, dustproof, and impact‑resistant reliability. With its combination of performance‑oriented reticle, large viewing window, and durable construction, the HS507‑PROMAX‑RD‑PRS is well suited for competitive shooters, everyday carry pistols, and duty platforms.
