The .50 caliber Umarex Hammer didn’t alter the laws of physics. It just took advantage of them. The Umarex Hammer’s primary objective was to accelerate a greater mass faster using technology, ingenuity, and a big .510 caliber barrel. Unlike a traditional firearm, the Hammer doesn’t generate a comparable report or recoil signature. A shooter in a hunting situation will not need to wear hearing protection when shooting the Hammer. The recoil of this big bore air rifle can best be described as a firm push, not a sharp kick like other rifles would give. The Umarex Hammer is not just another air rifle. It’s made for hunting big game.
The sheer energy and three full-power shots delivered by the .50 caliber Umarex Hammer is achieved through its proprietary, patent-pending, Lightspeed valve. The innovative engineering used to design this internal mechanism coupled with a .510 caliber, 550-grain lead slug is the recipe for making over 700 foot-pounds of energy at the muzzle. Almost as impressive, it only takes about two pounds of effort to operate its straight-pull bolt. This short, effortless action is all it takes to cock the rifle and advance the 2-shot magazine.
