The only reflector that I can find is the small ones for xml:
C8 reflector
Are there other sizes that I can get? I cant seem to find then on ebay/online shops.
Search keywords: Cree reflector
Are there bigger ones? I see Big reflector
Huge reflectors
They only come in 100$ lights and they are not sold by themselves. Anyone has any ideas?

Thank you my savior!
Ooh, I never saw that big SST90 reflector on DX before!
Nice… 8)

I like this reflector though its not cheap. Its the one in my monster light with MTG-2.
Where do you get the glass?
I will buy an MT-G2 on copper some time soon too…
Irresistible…

To figure out what lens size you need, you should really measure the I.D. of the bezel on the light. It has very little to do with the reflector dimensions.
Thanks for your help. These are also really good prices!
OL put me onto these.
The one I got but cant find anymore also had a ar coating on it. It is slightly bigger in diameter than the reflector.
Edit. You remove the lens from the frame.
That starts at about this low . 
That DX SST-90 reflector looks like the one used in the UF-T90.
