I've seen it before too. Thread adaptors are a horrible way to deal with cans, as you are asking for a baffle strike.
If you look on TBAC's website, they have a specific drawing for what they require for making barrel threads work with their direct thread-on cans, and we actually used that drawing in the 6.5 Grendel Reloading Handbook Volume II in the muzzle devices section.
TBAC also makes 9/16 brakes for their brake-attach cans, but it looks like you have a direct-thread-on can for 5/8x24. Just get your muzzle re-threaded, or get another barrel. This is not an area to play around with, as you will most likely get a baffle strike.
