Advise Sought on Sights for 603 FWB

[muldoon9]

Hello,
I hope to take delivery soon of a FWB 603.

My question is, can I install my adjustable Gehman front and
rear apertures ?

The changeing light , my age, and different shooting venues require me to
adapt.

Thanks for your help,

Michael

Michael,

I've got a Ghemann aperture on my 600 sights. The 603 probably has the newer sight but still the same aperture threads. Don't know about the front.

Congratulations on the 603.

The rear iris should be no problem, the front one will fit if it's a 22mm diameter iris, that's presuming it's a 22mm front sight on the 603 Colin
