556 Rearsight Anti-Glare Tubes

The Gehmann 556 Rear Sight Anti-Glare Tube is a lightweight, precision-machined accessory designed to reduce stray light entering the rear sight, improving sight picture contrast and helping shooters maintain a more consistent aiming image. Available in multiple lengths, it allows competitors to fine-tune their sight setup to suit individual preferences and changing lighting conditions.

Manufactured from lightweight aluminium, the 556 Anti-Glare Tube adds minimal weight to the rifle while providing effective protection against unwanted reflections that can reduce sight clarity. Its compact design integrates seamlessly with compatible rear sights, making it suitable for both competition and training use.

Each tube features a precision-cut M9.5 x 1 thread for secure attachment to compatible rear sight irises and accessories. The tubes can also be threaded together, allowing shooters to create custom extension lengths for enhanced flexibility. In addition to reducing glare, they can be used as a rear sight extension, increasing the distance between the shooter’s eye and the rear aperture to suit individual shooting positions and visual requirements.

Available in 25mm, 35mm and 50mm lengths, the Gehmann 556 Rear Sight Anti-Glare Tube provides a simple yet highly effective way to customise your rear sight system for improved comfort, consistency and optical performance.
