    I am building a flat top ar 5.56 upper and am piecing it together tomorrow. I have a 3-9 dusk and dawn to use now and am wondering which scope mounts to use in mounting it. I have a fsb and will also install a flip up rear sight to the upper. I would like a scope mount that mounts in a manner to allow use of both scope and iron sight... Any ideas?

    What ever mounts you use they must be high, very high. The stock of the AR is straight back from the receiver and regular height mounts makes the scope very uncomfortable to use.

    To determine how high, mount the gun on your shoulder as you would to shoot. Get a good face weld on the stock and have someone put a ruler on the top of the receiver rail to see how high your eye is above that rail by sighting from the front of the gun (obviously unloaded gun with the bolt locked open, for safety).

    I use the RRA one-piece cantilever mount on my AR in combination with my Magpul Gen 2 BUIS. It's between $55 & $60 depending on where you get it. I bought mine at Joe Bob Outfitters. It's very solid and allows for easy mount / dismount without any loss of zero. I'm very happy with the way it works. BTW, there's no way to use a scope AND irons at the same time. If that's a requirement, you'll need to go with an ACOG or Red-Dot sight mounted forward and do the whole co-witness thing.

    Thats what i thought. I may pop on an old carry handle until i save another $80 for a strikefire instead of spending $$$ on rings for a temporary scope.
