If I wanted a brake for this thread, I see Harrels radial brake is an option. Are there others?
If you want to know the thread pitch on your barrel, unscrew the muzzle device & take it to your local hardware store's fastener section, and find which screw size will thread into it. It's probably 3/4 x 28 if you have a heavy barrel, 9/16 x 32 if it's a slim profile barrel.
I'm actually ordering a Harrell's tactical brake myself, because I want one that matches the diameter of my Wilson Combat SR Recon barrel, and the price is right. The radial design is really similar to the WCI, so it could be a good change if you want something shorter, but performance would likely be diminished because it has fewer ports compared to the WCI.
