Burris optics? Any of these good?

[Chris D]

Anyone have any opinions on either of these two sights? I can get a great price ~$175 for either or $180 for the XTREME

BTW These are going on a flat top AR...

I have one of the Burris FastFire MRDs on my Mossberg SPX. It's only been through about 500 rounds so far but I haven't noticed any shortcomings in terms of construction.

What I was really impressed with the other day was the Burris XTR 1-4x (http://www.burrisoptics.com/xtrtactical1.html). A bit more expensive than you may want, but it seemed to be quite versatile.
