The Holosun PROMAX-TI-GD-PRS is a large-window open reflex pistol sight built with a Grade 5 titanium housing and slim bezel to minimize visual obstruction while maintaining IP67 waterproof and 5000G vibration resistance. Designed around the industry-standard RMR mounting footprint, it features an expansive 1.18 × 0.98-inch viewing window paired with an integrated forward-leaning sunshade that reduces overhead glare in bright lighting conditions. Equipped with Holosun's Gold Performance Reticle System (PRS), shooters can toggle between a crisp 2 MOA dot and selectable 8, 20, or 32 MOA circle options for high-contrast aiming across competition, training, and duty applications. It also includes 12 manual brightness settings (8 daylight and 4 night-vision) with Lockout Mode, Shake Awake motion activation, memory recall, and a side-loading CR1632 battery delivering up to 100,000 hours of runtime.
