The Holosun HS403C + HM3X Combo Pack delivers a complete optic solution for shooters seeking fast close-range target acquisition with the added versatility of magnified precision at distance. Combining the durable HS403C 2 MOA micro red dot with the rugged HM3X 3X magnifier, this setup is ideal for AR-platform rifles, PCCs, defensive carbines, and range applications.
The HS403C features Holosun’s advanced Solar Failsafe™ technology, allowing the optic to automatically adjust brightness based on ambient lighting conditions while providing a secondary power source when sufficient light is available. Paired with Holosun’s highly efficient LED system, the optic delivers up to 50,000 hours of battery life on setting 6 for dependable long-term performance. The optic also incorporates Shake Awake™ technology, which powers the sight on instantly when movement is detected and powers down during inactivity to preserve battery life without sacrificing readiness.
Built with a durable 6061-T6 aluminum housing, the HS403C is engineered for hard use while maintaining a lightweight and compact footprint. The optic offers 12 brightness settings, including 10 daylight and 2 night vision compatible modes, giving shooters flexibility across changing lighting environments. Its convenient side tray battery compartment allows battery replacement without removing the optic from the firearm.
The included HM3X magnifier features a rugged aluminum body and a quick-release ambidextrous flip-to-side mount for seamless transitions between unmagnified and magnified shooting. Supporting both absolute and lower 1/3 co-witness configurations, the HM3X offers flexible mounting options to match a variety of rifle setups. The magnifier also includes windage and elevation adjustments for precise alignment with the red dot.
Both optics feature IP67 waterproof protection, making the system resistant to rain, dust, and harsh field conditions. Combined with unlimited eye relief, parallax-free performance, and excellent optical clarity, the HS403C + HM3X combo delivers a highly capable and dependable optic package at an outstanding value.
