This video demonstrates a method for rifling a barrel at home using 3D printed inserts and electrochemical machining. The process involves inserting a 3D printed component into a tube, pumping saltwater through it, and applying electricity to corrode the inside, thereby etching rifling. The FGC-9 project is highlighted as a pivotal point in 3D printed firearm subculture, enabling the creation of firearms with no traditional firearm parts for under $500.
