That's a damn clean setup bro, very nice.
I have the 517, runs off AA's and has the built in 7mm riser, so it runs a lower 1/3 co-witness with my Magpul Gen 1 BUIS. Can't complain, although I run/use my BUIS most of the time. My EOTech doesn't have much, if any, trigger time on it. Actually thought about selling it, but I figured it's better than nothing, it's no Browe or Trijicon, but it gets the job done.
