The Holosun 407/507COMP is engineered for competitive pistol shooters who demand speed, precision, and an expansive field of view. Designed around a large 1.1” x 0.87” viewing window, this open reflex sight provides a wide field of view for faster target acquisition and improved performance under pressure. 507COMP features Holosun' s innovative Competition Reticle System (CRS), a dynamic multi-reticle setup that includes a 2 MOA center dot and 8 MOA, 20 MOA, and 32 MOA circle options. These reticles can be used individually or in combination, allowing shooters to customize their sight picture based on personal preference or stage requirements. 407COMP introduces a streamlined approach to competition optics, delivering fast target acquisition and clear sight tracking with a bold 6 MOA dot. Built on the proven COMP housing, it offers a wide viewing window and a lightweight, durable design optimized for speed in dynamic shooting environments. Powered by Holosun's efficient Super LED, the 407/507COMP series delivers up to 50,000 hours of battery life on setting 6, supported by a CR1632 side-mounted battery tray for quick and easy changes without removing the optic. The sight also features Shake Awake technology to automatically activate with motion and conserve power when idle, along with Lock Mode to prevent unintentional adjustments during use. Crafted from durable 7075-T6 aluminum, this optic is rugged, lightweight, and IP67 waterproof-rated for dependable performance in any environment. It uses an RMR footprint for broad mounting compatibility across full-size and compact pistols.
