The Hammer Carbine brings the proven big bore performance of the original Umarex Hammer into a shorter, handier package built specifically for hunting. The semi-bullpup layout trims overall length to 34.13" without sacrificing serious downrange energy - a 350-grain slug leaves the 23.25" barrel at 820 FPS with 523 ft-lbs of energy on tap. The upgraded 35 cubic inch carbon fiber tank is larger than the original Hammer's, delivering 4 full-power shots per fill at a maximum fill pressure of 4,400 PSI. An improved twin-shot pressure seal magazine feeds reliably in the field, while the threaded muzzle, M-LOK handguard, Magpul pistol grip, and Picatinny scope rail make it ready to configure for your hunt straight out of the box. .50 caliber (.510" bore) big bore PCP Bolt action, 2-shot pressure seal magazine 23.25" barrel - 820 FPS / 523 ft-lbs with 350-grain slug 35 cubic inch carbon fiber tank - 4 full-power shots per fill 4,400 PSI maximum fill pressure Semi-bullpup design - 34.13" overall length M-LOK handguard Magpul pistol grip Picatinny scope rail Threaded muzzle with barrel nut
