I have a lathe. I have all the required tools. I have the machining knowledge. I want it registered (if required) and I want to apply for the tax stamp. I just don't want to buy a $500~800 multi-cal suppressor when I can make one for $50 in materials and time. I'm just unclear about whether this is allowed and what steps must be taken. Like, if it is allowed, do I manufacture the suppressor and THEN register it/get the stamp?
