Titanium flash hider with 9/16-24 threads?

[rushmc1a]

I think Alexander Arms makes them

Has anyone found a source for titanium flash hiders with 9/16-24 threading??

I want to buy an AA barrel, but the 9/16-24 threading is throwing up a few road blocks. One is finding a lightweight flash hider. I have a titanium flash hider on another barrel already, and now there is no way I could go back to a heavy steel one!! I guess I'm just spoiled/picky I searched around at work(terrible access) and couldn't find any titanium flash hiders with 9/16-24 threading. A titanium adapter would work also...
