Some suppressors will allow you to do 1/2-28 thread, I know my suppressor will. It would cost me about $100 to buy the direct thread mount for 1/2-28 and a couple seconds to switch out. There isn't much technical info on the Wyoming Arms Suppressors on their web site.
You can also just buy a
Barrel Thread Adapter for $15, you'll also need some "rock set" or Loctite and some washers if you want to time it. I'm sure there is a gunsmith that can make an adapter that will give you 5/8-24 threads and make it look like part of your barrel. They could probably coat it to match as well.
