Rearsight Iris units provide the ability to manipulate the size of the aperture through which the shooter views the foresight and target. Many of them also provide the ability to insert coloured and/or polarising filters thus further tailoring the sight picture to the environmental conditions on the range.

The units shown below will fit all standard Air Rifle and Smallbore Rifle rearsights. Both Centra and Gehmann offer units for other threads, including Parker-Hale, Karabiner 31 and Sauer-Busk. Please contact us for further information.

Centra and Gehmann also offer a variety of units which include integral diopter lenses - these cannot be used under ISSF rules, and we recommend instead that shooters who require a visual correction instead purchase shooting glasses and visit an optician to obtain an appropriate lens.
