Gehmann 566 Rearsight Iris With 6 Colour Filter

GEHMANN 566 REARSIGHT IRIS WITH 6 COLOUR FILTER

The Gehmann 566 combines the legendary accuracy of the patented 510 iris with an integrated 6-filter colour system, delivering unmatched visual control for competitive and precision shooters. Designed for shooters who demand adaptability in changing light conditions, this rear iris offers fine-tuned clarity and focus like no other.

Adjustable from 0.5mm to 3.0mm, the iris ensures a true aim-point throughout its wide range. The six optically-flat glass filters—orange, light green, yellow, medium grey, dark grey, and amethyst—help sharpen contrast and improve sight picture across all environments.

Constructed with a removable steel threaded connection for easy maintenance and compatibility, this rear sight unit can also be used without filters as a traditional iris.
