I have it with an absolute co-witness, but don't like that it's so busy - I want to move to a lower third setup and need to figure out what base plate to use to raise the viper without obstructing the iron sights.
I used the same screws and all is good. About the co-witness thing, I'm inclined to agree. But now that I have the Viper zeroed correctly I'm getting used to it. The Venom may be better for lower third.
