Anyone use the Trijicon RMR?

I am looking at the dual illumination Trijicon RMR and wondered if anyone has tried it on their Kriss yet. If so what MOA dot did you go with and what is the best riser size to co-witness with the Kriss flip up sights?

i run the rmr on mine. i've got the 9.0 MOA with a 2cm rise mount that does great for co witness. I do wish i had the 7.0 MOA, though, the reticle is pretty bright so you won't have an acquisition problems with the smaller reticle

Did you get the LED or dual illumination one?

I check them out at the shot show today and I was very interested
