The Holosun 507 Pro Max (brand part no. HS507-PROMAX-RD-PRS) is an open reflex competition optic built around an enlarged viewing window and Holosun’s red Performance Reticle System, giving pistol shooters a fast, flexible sight picture. Holosun machines the housing from 7075-T6 aluminum with a forward-leaning, glare-reducing sunshade, and the optic mounts directly to the industry-standard RMR footprint for broad slide and mounting-plate compatibility. A side-loading CR1632 battery tray allows battery changes without removing the optic from the slide, and Solar Failsafe backup power keeps the reticle running even if the battery runs down, making the 507 Pro Max a strong fit for competition and duty shooters who want a large window with selectable reticle geometry.
