The ZB47 submachine gun is a unique Czech design featuring a massive 72-round straight magazine. To overcome feeding issues with standard tapered 9mm Parabellum cartridges, Brno developed a custom, perfectly cylindrical 9mm round. The weapon's bolt mechanism incorporates specific teeth to interact with the magazine and feed rounds into the chamber.
This review explores six uniquely designed firearms, from WWII's Krummlauf STG-44 for urban combat to the industrial 3-gauge Kiln Gun. It highlights the extreme power of the A-Square .577 T-Rex, the historical novelty of the Coffee Mill Sharps, the experimental Gyrojet Rocket Gun, and the Velo Dog revolver for cyclists. The video emphasizes purpose-built designs and their often-quirky historical contexts.
