Hmmm. Are they going to ban stamped sheet metal and springs? ‘Cause it doesn’t take that much know how to manufacture them.

Manufacturing the parts to convert a semi-auto into a full auto isn't hard either. If you do it, it may land you in prison. The federal assault weapon ban limited manufacture of high cap mags too. The ones manufactured after the ban were stamped with "For Law Enforcement Use Only".

My point is that such bans are meaningless, unless the population willingly co-operates. People have known how to make bangsticks since the 1400s, and the means to manufacture them are abundant. Unless the Govt. intends to control the materials and milling machinery, the ban is not enforceable in the face of an unwilling population.

Your average citizen mechanic could not manufacture a tank to match modern standards, but a homeshop metalworker could make a mighty serviceable fully auto rifle with magazines to feed it. Kalashnikov, Shepard and Turpin, and John Moses pointed the way, and did the design work. The knowledge genie is long out of the bottle.
