What is a Duo-Iris-aperture insert?

Unlike a normal adjustable aperture insert , the outer and inner diameters of the ring front sight can be adjusted independently of each other. This allows the shooter to optimally adjust the front sight from a very narrow to a very wide width to his individual needs.

The Duo-Iris-aperture insert is available as a free-standing aperture insert - mounted between glass panes - and as cross hair-aperture insert. The Duo-Iris-aperture insert with cross hair offers a switchable reticle (lateral hair/cross hair) and continuous adjustment of the cant angle. Two diameter ranges are available. The Duo-aperture insert can thus be used in all disciplines.
