That is the same thread pitch as used on 9mm ARs. It is also a retarded choice. Almost all 308 suppressors and flash hiders are 5/8"x24. You could use a 9mm flash hider though...
I was looking at this too. Model 1 won't thread it 5/8x24, I asked them. I found a place, www.trosusa.com , that will make an adapter from 1/2x36 to 5/8x24 for $64.
