He fabricates the massive replica from scratch using metalwork, incorporating a motor-driven feeding system, a clutch mechanism, and a working blowback feature using off-the-shelf parts and custom electronics. The finished, non-firing model successfully demonstrates realistic cartridge ejection and mechanical recoil.
