The 9/16x24 muzzle devices (in my experience) are smaller diameter. I have a Smith Vortex on an AA Shaw barrel (9/16) and it blends in nicely. I have a 5/8x24 YHM flash suppressor on another barrel and it looks like a huge weight hanging off the end (more than an extra 1/16"). I have no experience with other brands, so I have no idea if they are similar.
