BUIS that fits under a magnifier?

[pb_blade]

Hey all, so I've put an Eotech 552 on my flattop AR, and soon a magnifier will go behind it on a flip-to-side mount, and i'd still like to toss on one of those flip-up backup iron sights. I've got a UTG flip up BUIS right now.... but i don't know if it'll fit even in the down position when the magnifier's on. Any thoughts? any other option than the Rock River low profile BUIS selling on questar for about $170?

Arms#40 fits (with a flip to side mount)
Won't extend with the mag in front of the Eotech but who cares

Troy and KAC work very well under a Larue flip magnifier mount

As mentioned above Troy works well in that arrangement.
