I have an older British made Webley Tomahawk break-bbl rifle and would like to ask if anyone has removed the factory muzzle break and replaced it with a suppressor. It looks simple and I expect to find a threaded tip but I’m just guessing and don’t want to damage the muzzle break. These are getting scarce and I would like to be able to return it to factory specs later. Anyone know where I can get a parts diagram for this?
