The Williams Gun Sight .406'' Fiber Optic 406N Front Sight in Steel Red is a practical upgrade for hunters and shooters running centerfire rifles or muzzleloaders. This fiber optic front sight uses ambient light to keep your sight picture bright and visible—the more light available, the more vivid that red bead glows. Unlike traditional iron sights that can fade or blur in harsh conditions, this design resists washout even under intense sunlight, giving you a reliable aiming reference from dawn to dusk. If you're building or refurbishing a rifle and want a front sight that performs without batteries or complex installation, this is a straightforward choice.
Williams Gun Sight has been making iron sights for generations, and this fiber optic model reflects their engineering fundamentals: durability, simplicity, and real-world usability. The .406'' bead size is a classic, proven dimension that works well for hunting distances and general rifle shooting. Installation is straightforward on ramps that accept Williams Streamlined and Shorty Sight configurations, making it a drop-in solution if your rifle is already set up for Williams components.
Whether you're sighting in a deer rifle, setting up a muzzleloader for fall season, or maintaining a working rifle that's been in the safe for years, a quality fiber optic front sight is often the best low-maintenance answer. You get the speed and simplicity of iron sights without the limitation of relying on your eyes to pick out a dark sight bead in changing light. This Williams 406N delivers that advantage in a proven steel platform.

The Williams .406'' 406N is designed to fit rifles equipped with Williams Streamlined and Shorty Ramps. If your rifle already wears Williams sights or was designed to accept them, this front sight will install directly. Check your rifle's sight system or contact us if you're unsure about fitment.
Yes. This Williams sight is suitable for both centerfire rifles and muzzleloading rifles, provided they use compatible Williams Streamlined or Shorty Ramp bases.
Fiber optic sights depend on ambient light to glow. In very dim conditions or dense shade, the red bead will be noticeably dimmer than in bright daylight. They shine brightest in typical hunting and range light. For very low-light use, you may prefer to pair iron sights with a separate light or consider other aiming solutions.
Williams sights are built from quality steel designed to withstand the recoil and field use of hunting rifles. The fiber optic elements are protected within a robust housing. With normal use and care, this sight will provide years of reliable service.
