The Holosun 407C-X3 2 MOA red dot open reflex sight (Holosun part no. HS407C-X3-RD) refines the 407C platform with a reinforced 7075-T6 aluminum housing and a crisp 2 MOA red dot. It mounts on the RMR footprint, runs on a side-loading CR1632 battery and combines Solar Failsafe with Shake Awake. Holosun rates the runtime at up to 100,000 hours. A forward-facing light sensor adjusts brightness on its own, so the dot stays visible as lighting changes. It is a straightforward, durable optic for an optics-ready duty or carry pistol.

Key Specifications

• The reticle is a 2 MOA red dot, small enough for precise shots and quick enough for close work.
• The emitter is a 650nm red Super LED, which gives a bright dot with efficient power use.
• Mounting uses the RMR footprint as a direct mount, so it drops onto many optics-ready slides without an adapter.
• Solar Failsafe adds backup power from a solar panel and adjusts brightness automatically in changing light.
• Shake Awake turns the dot on when it senses motion and powers down when idle to protect the battery.
• The battery is a CR1632 in a side-loading tray, so replacement does not require taking the optic off the slide.
• Runtime is up to 100,000 hours on one battery at setting 6, long enough to forget about battery changes for years.
• Brightness has 8 daylight and 4 night vision compatible settings, with memory and a lockout mode against accidental changes.
• The housing is 7075-T6 aluminum with a black anodized finish and IP67 waterproofing, with 5000G vibration resistance.
• The window measures 0.91 by 0.67 inches, and adjustments are 1 MOA per click for zeroing.
