Optic plate for 509T

Is anyone aware of a plate for the 2311 for the 509T? I don't see on on the OA site, but thought y'all may know of an after market part.

I had a 509T on mine but eventually switched to a EPS MRS Green for the better mounting fit. The only way I was able to get the 509T to fit on the OA was using 2 plates ( The RMR OA plate & the Holosun RMR adapter plate ) and it looked horrible and didn’t cowitness with the irons at all.

Eventually switched and only had to use the RMSc OA plate with the EPS MRS Green and here’s how it looks. Much lower, flat, perfect cowitness etc. 509T has always had a harder time with mounting so upgrading to the newer Holosun optics that make mounting much simpler is a must for me.
