The World’s Largest Working Rifle has earned global attention for pushing the limits of firearms engineering. Built in the United States, this extraordinary weapon is a fully functional 30mm rifle, widely recognized as the largest rifle ever designed to be shoulder-fired and operational.
Engineered by Anzio Ironworks, the rifle dwarfs conventional firearms in both size and power. Chambered for massive 30×173 mm ammunition—normally used in military aircraft cannons—the rifle weighs well over 50 kilograms and requires a specially designed mounting system to manage recoil and stability. Despite its intimidating scale, it is fully operational and capable of accurately firing live rounds.
What sets this rifle apart is not just its size, but the precision engineering behind it. Designers had to overcome immense challenges related to recoil absorption, barrel stress, heat dissipation, and structural integrity. Advanced materials and custom-built components were used to ensure the rifle could safely handle forces far beyond those of traditional small arms.
Weapons experts describe the rifle as a showcase of mechanical ingenuity rather than a battlefield tool. It is primarily used for demonstration, research, and extreme long-range shooting, offering insight into how far firearms technology can be pushed when conventional limits are removed.
The rifle has been featured at firearms exhibitions and demonstrations, where it continues to draw crowds of engineers, defense enthusiasts, and record watchers. Its thunderous firing and cannon-like presence blur the line between small arms and heavy weaponry.
Guinness-style record authorities and firearms historians widely regard it as the largest working rifle ever constructed, cementing its place in global record lore. The achievement highlights how innovation and craftsmanship can transform an idea once thought impractical into a functioning reality.
