I'm very happy with the 10-8 Performance low profile "standard height" rear and Heinie black .215" front. This combination is what I use for my 19.5 MOS with Steiner MPS and FCD/TD ACRO plate, but it will also work for the Holosun EPS with DPP plate.

The profile of the rear sight is tapered as it gets to the top, it is serrated for less glare, has a melonite finish so it doesn't rust, and it has a set screw. It is also not sharp unlike some other sight sets I've had.
