The Holosun HE407C X3 is an open-emitter pistol green dot on the updated X3 platform — refined housing, improved ergonomics, and a forward-facing light sensor for adaptive brightness. It carries a clean 2 MOA green dot on the RMR footprint, fitting the huge range of RMR-cut slides and mounts.
Solar Failsafe auto-adjusts brightness and backs up the CR1632, while Shake Awake and Lock Mode keep it ready and secure. 7075-T6 aluminium housing, IP67, 5000G-rated.
