I was just toying around with an idea here. Is it possible to make a threaded barrel for a gun that does not have one? what I'm getting at is replacing the existing non threaded barrel (for a supressor) for a barrel that is threaded for a supressor. I could probably find a replacement barrel but wouldnt the length have to be diffrent for the adapter? and could one be made? I have a couple of guns I'd like to have threaded barrels on that are currently not available. Just an idea.
