The Holosun HE507 Pro Max Open Reflex Multi-Reticle Green Dot Sight is built to give pistol shooters a wide, uncluttered view with fast, precise aiming. Its enlarged 1.1 x 0.87 inch window, forward-leaning sunshade, and multi-coated glass work together to keep the green Performance Reticle System crisp and visible in bright daylight or low light. With options for a 2 MOA dot and 8, 20, or 32 MOA circles, you can tailor the sight picture to your preferred balance of speed and precision.

This model is ideal for range work, competition, and dedicated training on full-size pistols where a larger window speeds up target transitions. Solar Failsafe, Shake Awake, and a side-loading CR1632 battery provide long-running reliability with minimal maintenance, while the 7075-T6 aluminum housing and IP67 waterproof rating stand up to hard use. It reflects Holosun’s focus on practical innovation and durable, shooter-focused optics.
