HiViz M400 Magnetic Front Sight Green/Red Fiber Optic Black

The HiViz M400 M-Series Magnetic Front Sight transforms target acquisition with its bright fiber optic technology and tool-free installation system. This front sight delivers enhanced visibility in varying light conditions through its green fiber optic with red center configuration. The magnetic mounting system allows shooters to quickly attach or remove the sight without permanent modifications to their firearm.

What Makes This Different

Unlike traditional dovetail sights that require gunsmith installation, the M400 uses a powerful magnetic base that secures firmly to steel front sight posts. The dual-color fiber optic system provides superior contrast against diverse backgrounds compared to single-color alternatives. The sight maintains zero consistently while offering the flexibility to remove it for cleaning or storage without losing sight picture.

Key Features

• Magnetic mounting system for tool-free installation and removal
• Green fiber optic with red center for maximum visibility contrast
• Compatible with standard steel front sight posts
• Durable polymer construction with protective sight guards
• Maintains consistent zero through multiple installations
• No permanent modifications required to firearm
• All-weather performance in rain, snow, and extreme temperatures

The M400 excels in competitive shooting where rapid target transitions demand instant sight picture acquisition. Law enforcement professionals appreciate the ability to quickly configure their duty weapons for different lighting scenarios. The fiber optic system gathers ambient light effectively during daylight hours while remaining visible in low-light conditions. The magnetic connection withstands recoil from standard rifle cartridges while maintaining precise alignment.
