The Holosun EPS Red 3MOA Dot Enclosed Sphere Lens Solar Shake Awake Slim Base 7075 Pistol Reflex Sight is a compact, enclosed reflex optic that delivers a clear 3 MOA red dot in a slim RMSc footprint suited for pistols with limited slide real estate. Its enclosed design protects the emitter from dust, debris, and weather while a forward‑facing light sensor with automatic brightness adjustment keeps the reticle visible across changing lighting conditions. The sight is powered by a side‑tray CR1620 battery with up to 50,000 hours of runtime and includes Shake Awake with Lockout Mode for intelligent power management. Built with a rugged 6061‑T6 aluminum housing with a hard‑anodized finish, it is IPX8 waterproof and 5000 G vibration rated for durability, offers parallax‑free 1× viewing with unlimited eye relief, and provides 1.5 MOA windage and elevation adjustments with ±30 MOA travel for precise zeroing.
