Matech with Magnifier

[BigMat]

I am thinking about picking up a magnifier for my rifle and would like to get a flip up BUIS for it, I am leaning towards a Matech as they seem to have an alright reputation and can be had for a good price. Any experience with these, are they any good?

They seem alright, had one on my issued M4 when I was in Iraq. Never got the damn thing zero'ed the way I wanted it, but I had a ACOG ontop so it wasn't that big of a deal. The way its setup, you'd think it was some type of Target sight.
