Thunder Mountain Custom Fiber – Bright, Durable Red Fiber for Firearm Sights – Red – .060

Upgrade Your Sights Fiber with Unmatched Brightness

Thunder Mountain Custom Fiber delivers exceptional brightness, flexibility, and durability for firearm sights. Unlike standard fiber replacements, this high-quality fiber ensures your sights remain visible and precise in all lighting conditions. Whether you are shooting in bright daylight or low-light situations, this fiber stands out, helping you acquire targets faster and more accurately.

Optical-Quality Core for Maximum Light Transmission

The fiber is constructed with an optical-quality polymer core, doped with highly efficient fluorescent dyes. A low-refractive-index fluoropolymer coating surrounds the core, allowing visible and even ultraviolet (UV) light to fluoresce. Consequently, the light transmitted through the fiber appears brighter and more vivid than conventional options—over 30% brighter, even on cloudy days.

Durable and Flexible for Tough Environments

Thunder Mountain Custom Fiber isn’t just bright—it’s also incredibly strong and flexible. Its resilience makes it ideal for harsh environments, rough handling, or repeated adjustments, ensuring your sights maintain performance and reliability over time. Even under repeated bending or exposure to solvents, the fiber retains its integrity, providing consistent performance shot after shot.

Precision for Competitive and Tactical Shooting

Thanks to its superior optical properties and strength, this fiber excels in competitive, tactical, or recreational shooting applications. The bright red color allows for fast, intuitive sight alignment, while its flexibility enables perfect cutting and fitting for your sight needs. As a result, you achieve professional-grade performance that enhances both speed and accuracy.
