Picatinny quick-detach scope mount for flat-top AR?

Adding a scope setup to my AR but want the capability to quickly add/remove the scope so I'm looking for a quick-detach setup.

So far I've been having a hard time finding the super tall rings in a quick-detach configuration for the flat-top AR - can somebody point me in the right direction?

Other alternatives I've seen are getting a couple small 1/2" risers but am afraid they would get in the way of the iron sights - I'll have to take some measurements tonight...

I also have flip down BUIS that I would like to keep installed at the same time as the scope.

Thanks!

Larue is the best QD AR optic mount.

If you need a higher mount, you may want to look at this one:

I have used the B-Square one piece mount with built in rings.
It is not considered quick detach as it has no throw levers but it has large screws that at most need a coin but usually are used on my guns finger tight.
It is fairly high ,works well with fixed or adjustable type stocks and is cantilevered to allow quite a range of eye relief adjustment. I find it returns to a fairly closr zero if one keeps track what groove you are lining up with.
I am not sure B-Square still makes this but Armalite and several other folks make similar units

Use of a rail mounted BUIS behind a scope would usually push the scope so far forward that eye relief would be exceeded.BUIS usually
only are paired with dot or holograph type sights that are non critical for eye relief

Actually, BUIS can be installed on optics-mounted AR's depending on the setup. The key is to have flip-up rear BUIS that is low enough that it sits UNDER the optic without interfering with it.

Most people who put BUIS on their magnified optics AR platforms look for a low flip-up sight such as the ARMS 40L or the Troy Flip-up.

At the moment, I have a CAA mount on my AR as well as my LR-308. I am using YHM flip-up rear sights on both rifles as BUIS. While YHM are not the lowest rear BUIS, they sit under a Millet DMS-1 and a Leupold Mark 4, respectively.

The beauty of ARs that that SOMETHING exists that will work in most cases.

Sounds like we're going to have similar setups since I have the YHM flip up rear site and will be putting a Leupold VX on mine.
