All that different threading just confuses me. -YFortunately I found on old HW rear peep to go on my 10M gun. Airgun shows are great for that kind of stuff.If somebody knows the threading, please let me know.
MDriskill Do you find when comparing aperture openings that the Gehmamm opening is larger. I have a fixed peep of .050" converting mm to inches , it should look the same but the markings don't seem to match in size.Chris

Airgun shows are great for that kind of stuff.If somebody knows the threading, please let me know.Just about all German airgun sights (Weihrauch, Diana, FWB, Hammerli, Steyr, Walther, Anschutz) going back to the 1950's use the same eyepiece thread: 9.5mm x 1.0mm. The Gehmann and Centra accessory irises fit them all, and the OEM eye disks easily move between brands.Per my post above, just two pieces: a German-thread iris, and the adapter for fitting it to the US thread; will let you have an adjustable opening on pretty much any air rifle out there.
