What supressors can be had with threads that match the TRG22? Also does anyone make an adapter to go from the TRG thread to a more universal thread for a common can? Not sure what negative effects an adapter like this might have. I have seen where one smith cut a few inches from the muzzle making a small screw in piece of barrel which connects to the remainder of the barrel with a common thread. While this is clever, I would really like to keep the rifle intact. Are there any other options?
