The .50 caliber Umarex Hammer is made for big game hunting as you’ve never hunted before. A high-pressure big bore air rifle engineered for an ethical harvest.

The .50 caliber Umarex Hammer Airgun Hunting Rifle 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, innovation, and the big .510 caliber barrel. This unparalleled air rifle will push a 550-grain slug to 760 FPS and generate 705 ft-lbs of energy at the muzzle. To put that in perspective it is nearly 10X more powerful then the 22LR and 2X more powerful then a 45 ACP! Unlike a traditional firearm, the Hammer doesn’t generate a comparable report or recoil signature. A shooter in a big game hunting situation will not need to wear hearing protection when shooting the Umarex Hammer. The recoil of this big bore air rifle can best be described as a firm push, not a sharp kick like a powder burning rifle would give. Its dual-chamber precision magazine means you’ll have an immediate follow-up shot if needed and each Umarex Hammer comes with two magazines. The Umarex Hammer is not just another air rifle. It’s in an air rifle hunting class all by itself.
