iris for FWB 600

I just bought a used FWB 600.
Will the front sight accept 18 mm adjustable irises like Gehmann and Anschutz?
Will the rear sight accept a Gehmann 510 adjustable iris?
Thanks for the help.

The FWB 600 was fitted with a 16-mm fore sight tunnel, [unless of course some one has changed that] Later 601 models were fitted with 18-mm tunnels, and 603 models onwards were 22-mm
The Gehmann rear sight iris should screw on to the back sight.

But the good news is that if you have the older 16mm front sight tunnel the entire front sight can be replaced with either an 18 or 22mm unit. I know Centra makes them for sure, I am not sure about Gehmann. I would also expect Feinwerkbau could supply one.
How do you tell, remove the aperature, if the entire aperature measures just over 5/8 diameter across it is 16mm, if just over 11/16th of an inch it is 18mm.
