The HS507-PROMAX-PRS is Holosun's flagship open pistol sight for 2026, built around the Performance Reticle System (PRS) — a selectable reticle offering a 2 MOA dot with 8, 20, or 32 MOA circle options for adaptable speed or precision shooting. The enlarged 1.18" × 0.98" competition window delivers a wider field of view for faster target transitions, while the integrated forward-leaning sunshade reduces glare and keeps the reticle sharp in bright conditions.
Powered by a side-loading CR1632 battery tray for optic-on replacement, Solar Failsafe for automatic brightness assistance, and Shake Awake for instant activation, the 507-PROMAX is engineered for demanding competition and duty use. The 7075-T6 hard-anodized aluminum housing provides IP67 waterproofing and 5000G vibration resistance on an industry-standard RMR footprint.
