Made for big-game hunting as you've never hunted before, the Umarex® Hammer .50-Caliber Big-Bore PCP Hunting Air Rifle generates power without powder for an ethical harvest. An unparalleled combination of technology, ingenuity, innovation, and the big .510-caliber barrel combine to push a 550-grain slug at 760 fps and generate 705-ft.-lbs. of energy at the muzzle. The Umarex Hammer is not just another air rifle. It's in an air-rifle hunting class all by itself. 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 this air rifle. The recoil can best be described as a firm push, not a sharp kick like a powder-burning rifle would give. Precharged Pneumatic (PCP) operates with high-pressure air from the 24-cu. in. non-removable carbon-fiber tank. Optimal operating fill pressure equals 4,500 psi with each shot regulated to 3,000 psi. A fill of air cylinder delivers 3 full-power shots and a 4th shot at approximately 90% power. The dual-chamber precision magazine means you'll have an immediate follow-up shot if needed; 2 magazines included. The Hammer .50-Caliber Big Bore PCP hunting rifle allows degassing and has a built-in manometer (pressure gauge). Walther® German-made 29.5" barrel with 1:24 rate-of-twist rifling and full-length composite shroud. PolyOne-designed and U.S.-manufactured stock with AR Magpul-style grip. Quick-disconnect Foster fitting for easy air-fill connection. Picatinny riflescope rail for scope mounting. 3 slots in forearm grip accept M-LOK attachments. Straight-pull speed bolt with 8-lb. cocking effort. 2.5-lb trigger weight. 3 mechanical safety devices. Integrated rear sling stud. Overall Length: 43.75". Wt: 8.5 lb. (unloaded).
