The Holosun 507Comp-GR is an open-emitter reflex sight optimized for competitive shooting, featuring the green CRS (Competition Reticle System). The CRS reticle offers multiple selectable options: a 2 MOA center dot, 8 MOA ring, 20 MOA ring, or 32 MOA ring, all configurable independently or in combination. This model is designed around an enlarged viewing window for faster target acquisition and improved peripheral awareness under pressure.

Built from 7075-T6 aluminum with a hardcoat anodized finish, the 507Comp-GR uses a top-mounted CR1632 battery offering up to 50,000 hours of runtime (dot only, setting 6). Solar Failsafe ensures continuous operation in changing light conditions, while Shake Awake powers the optic on with motion and off after inactivity. The sight mounts via Holosun’s standard RMR footprint, making it compatible with a wide range of direct-mount slides and adapter plates.
