Adding a rail system to a 6920. It appears the longest traditional style rail I can do is 7" such as that offered by Daniel Defense. Do I have any better options? I'm not interested in removing the gas block front fixed sight and frankly, I think the rails that have sections removed to accommodate the front sight are rather ugly.

KAC's RAS for a simple drop in rail is the way to go.

Lots of 7" rails to choose from.q

I've run the DD Omega in the past, and it does the job great.

The KAC RAS is a good option as well.

I just installed a Centurion rail for a friend, and it would probably be the one I'd use if I were in your shoes.  Allows you to free float the barrel without having to remove the FSB.

I have a DD Omega 7" on mine. I haven't had any issues with it. the Centurion C4's are another great option. Midwest Industries also has some 2 piece free floats as well but I have zero experience with them.

You can always shave the front sight post down so it's basically a low profile gas block.  It's really easy to do with some basic tools in the garage.  Then you can run any rail that attaches to the factory barrel nut (Centurion, Fortis, etc), or take the factory nut off and run whatever rail you want.  Problem solved.

I ended up putting a Fortis rail on mine and I love it.

I've been out of the AR game for quite some time. These do look like very appealing options. Any more info you can provide on them? I assume they are lightweight and stout.

I have a low profile gas block and a 15 inch rail on my 6920.

Looks like this will be the route I'll be going after seeing the new rail systems out there.
