Angry Bear Arms Fiber Optic Sights for Glock MOS

Angry Bear Fiber Optic Sights for Glock^® MOS

The Angry Bear Fiber Optic Sights for Glock^® MOS are premium, American-made upgrades for shooters who want faster sight acquisition and improved accuracy. Proudly made in the USA by Angry Bear Arms, these CNC-machined sights are built from high-quality materials and held to tight tolerances for consistent, reliable fit. Designed specifically for Glock^® MOS slides, these sights offer superior performance in both daylight and low-light conditions, thanks to their brightly illuminated fiber optic front post.

Available in both low and tall profiles for small and large frame Glock^® models, these sights are a perfect upgrade for defensive pistols, competition guns, or optic-ready builds. The rear sight features a blank, serrated face to reduce glare, while the front fiber optic insert is easily visible in bright environments. The included red and green fiber optic rods let shooters choose their preferred color for optimal sight picture clarity and speed.

Each sight set includes a fiber optic front sight, a blank serrated rear sight, two mounting screws, and two fiber optic rods (green and red). These sights are compatible with slides featuring an optics cut and are designed with a 0.125″ rear notch and shortened front ledge to ensure a proper fit with popular MOS configurations. Choose the correct height and frame size option based on your specific Glock^® model and intended application.

Angry Bear Arms also offers blank sight sets and tritium-equipped versions for users with different preferences. Whether you’re fine-tuning your MOS build or simply upgrading your factory sights, these fiber optic sets deliver performance and visibility you can trust.
