The Anzio 20mm rifle is an American anti-materiel rifle designed and marketed by Anzio Iron Works. It is the first American anti-materiel rifle designed and mass-produced for public sale with a bore diameter in excess of .50 caliber in over 80 years.{{Cite web|url=http://www.tactical-life.com/online/tactical-weapons/fbi%E2%80%99s-20mm-hard-target-blasters/?right=related|title=Tactical Life: FBI’S 20MM HARD-TARGET BLASTERS|accessdate=23 April 2023}} The rifles are available in three calibers, with the rifle's predominant chambering being the 20mm Vulcan caliber.{{Cite web|url=https://www.tactical-life.com/guns/anzio-ironworks-monstrous-20mm/|title=VIDEO: 3 Shots With the Mag-Fed Anzio Ironworks 20mm Sniper Rifle|first=Andre M.|last=Dall'au|date=1 August 2010|accessdate=23 April 2023}}

Features

Other notable features include an optional three-round detachable box magazine, a {{convert|49|in|m|adj=mid}} barrel, and threaded muzzle to accept either a muzzle brake or suppressor. The total length of the rifle is 2.5 meters.

Performance

At approximately {{convert|48,000|ftlbf|J|abbr=on}} of kinetic energy, the 20mm round, as fired out of the Anzio rifle, has nearly four times the energy of the .50 BMG cartridge fired out of a comparable rifle, which is around {{convert|12,200|ftlbf|J|abbr=on}} of kinetic energy. The .600 Nitro Express, the second most powerful African big-game rifle cartridge, has around {{convert|8,200|ftlbf|J|abbr=on}} of kinetic energy. This makes a 20mm Anzio rifle 5.85 times as powerful as a rifle chambered in .600 Nitro Express.

The Anzio 20/50 has approximately {{convert|22,000|ftlbf|J|abbr=on}} of kinetic energy with an {{convert|800|gr|adj=mid}} bullet. It does this by taking the .50 BMG projectile, which already is relatively large and travels extremely fast, and increases the already supersonic bullet to over 1.3 times its normal flight velocity, creating more kinetic energy without the need for a larger and heavier projectile. Though its kinetic energy is significantly lower than the 20mm round, it is almost as effective due to its smaller surface area, meaning that it has less material to punch through, making it easier to penetrate, but the lighter bullet makes transferring energy over longer distances and into targets less efficient.
