The homebuilt gun scene is coming back. 200 years ago all kinds of people used to tinker and build guns. John Browning converted a lever-action rifle to a machinegun when he was young. Recently, a Japanese man with no training in firearms manufacture designed his own primitive blank firing revolvers, and many people have built fully operational repeating firearms with tools and parts being less than $500 USD. As things progress the traditional controls the production and trade of arms will become useless and the UN will have no choice but to give up on global civilian disarmament. Unfortunately, no fully-automatic exploding-flechette pistols for us just yet. Some day.
