Does anyone know of anyone that manufactures a bull barrel for a TS2? I'm looking at setting up my TS2 with a checkmate style compensator. But in order to do so I need to take out the factory bushing. And I would still like to be able to run a barrel without the compensator. Hence the need of a bull barrel as well. Also does anyone have a clue where I could find a checkmate guide rod or the specs for one so I could make one
