Need a Folding BUIS w/Elevation?

[T.A.Sharps]

Hey Everyone,
I need a little help finishing my sight system on my M4.

I have an M4 with a standard front sight, rail on the receiver.

I am looking for a good BUIS with an elevation adjustment. I would like a folding sight, but most everything I see with E is a fixed sight.

I plan to get a scope, but at first I want to shoot it with iron sights, however when I get optics for it I don't want to just get rid of my iron sights.

I actually am wanting to test the accuracy of the mounting system and be able to switch from optics, detach them, and use the iron sights.

YHM has a folding sight that "says" has elevation adjustments, but when I look at it online I only see the windage knob, and I don't see how the E adjusts.

Thanks
