FWB 300-s modern sites

[Richmeister]

Hello,
I'm wanting to find a riser block for the rear site of my fwb 300 s. I've recently fabricated a front site mount for an adjustable iris 22mm front globe.

However the original rear site doesn't have enough elevation and shots are hitting 1.5" - 1.750" low.

Is there a riser block available that will work?
Otherwise I'm not opposed to buying a new "modern" site but would also need to know what one that would be compatible with the rounded receiver of the rifle.
I read a lengthy post about someone with a fwb 2000 rimfire that was up against this similar task but the thread never continued so I didn't find much more information on the subject.
Hopefully there's someone who has done, or knows someone who has done this.

If all you are looking for is riser blocks they should be available from Champions Choice. I have the on my 8002 annie air rifle.

Both Centra and FWB make a 4mm raiser block to fit FWB dovetails. This should be enough to zero at 10M with the tall

I found some from another member.
