The Gehmann 523-22LUX M22 Front Sight is an advanced competition foresight designed to significantly improve sight picture clarity by increasing light transmission to the front iris. Developed with enhanced optical performance in mind, it features a unique translucent front-end tube that allows more ambient light to reach the aiming system, resulting in a brighter, clearer and more defined sight picture—particularly beneficial in low-light conditions or for shooters requiring improved visual contrast.
Precision-engineered for use with M22 front sight elements and irises, the 523-22LUX combines modern materials with Gehmann’s established reputation for accuracy and durability. The design integrates a specially developed frosted translucent plastic element with a high-quality silver alloy body, balancing strength with optimal light diffusion characteristics.
For shooters seeking maximum optical enhancement, the system can be further upgraded with the optional Gehmann 547-22 LUX transparent element collar, enabling a fully transparent foresight configuration for even greater light transmission and visual clarity.
The result is a highly specialised front sight system that enhances target definition and reduces eye strain, making it particularly advantageous for precision shooters, including those who benefit from increased brightness and contrast in their sight picture.
The Gehmann 528 "Double-Cross" Adjustable Foresight Iris is an innovative front sight accessory designed for target rifle shooters who want the flexibility to adapt their sight picture to suit different disciplines, targets and personal preferences.

This versatile system allows shooters to experiment with different aiming references without replacing the entire foresight insert, making it ideal for those seeking maximum adaptability.
The iris provides infinitely variable aperture adjustment, allowing the aperture diameter to be set precisely for optimum target definition and light transmission in changing lighting conditions. Smooth, continuous adjustment enables you to achieve the ideal sight picture for both training and competition.
The Double-Cross system uses only one side of the foresight, creating a clean and effective aiming reference while maintaining excellent target visibility. A plastic adjustment tool is supplied, allowing the insert to be safely rotated between the horizontal bar and crosshair configurations without damaging the precision components.
