Yes they make carry handle mounts. It does put the scope up pretty high and can set you up for some awkward cheek weld.
Best option is to get a flat top and build another upper that you could pop on if the indtended use really requires a scope. If not there is a certain elegant simplicity to the carry handle rifles and sights. They are fairly rugged and easy to use.
If you tell us what kind if use you are trying to mount an optic for then there may be other options out there.
Do you want an optic scope, or a red dot holographic type scope? I have seen Trijicon and Mepro21s make scope mounts for the carry handle AR's. Instead of sitting high, above the mbus, they sit forward of the handle, and you use the mbus to co-witness through the holographic sight.
