What's already been said.  Figure out if you want a fixed or a flip up BUIS.

If you're not going to get an optic I'd definitely go fixed.  If so it's probably more popular with flip up btu either will work.

I'm running a LaRue fixed BUIS behind an Aimpoint CompML2 at 1/3 lower cowitness.

Don't forget that Troy has a pretty nice fixed rear too.

If your not going to put an optic on it, stay with the carry handle sight. When I went to mount eotech on mine, I looked at all the options to get it up there with a BUIS and found no room w/o going to a railed handguard. I didn't want to bolt a bunch of stuff on it. I took a chance on the RRA Dominator 2 eotech mount with the A2 sight. This thing is perfect. you can use to optic or the irons on there as well. Got mine new on gunbroker for 140 delivered.

I use a Troy flip up on my Colt and Magpul on my others.

Leave your carry handle on if all you are going to use is iron sights.

I've got the Magpul MBUS rear sight on mine. Folds down nicely leaving room for your optics and only cost $55.
