Umarex Hammer .50 Caliber PCP Air Rifle – OD Green/Black | High Power, Precision & Durability
Umarex Hammer .50 Cal PCP Air Rifle, OD Green/Black
Dominate the hunt with the Umarex Hammer .50 Cal PCP Air Rifle, America’s most powerful production airgun. Delivering over 700+ foot-pounds of regulated muzzle energy using massive 550-grain .50 caliber lead slugs, this big-bore air rifle fires with a velocity of 760 FPS, offering firearm-comparable performance with significantly reduced recoil and a softer report.
Overview
While air rifle hunting is becoming increasingly popular, the Umarex Hammer redefines big-bore capability. Unlike powder firearms that deliver a sudden punch, the Hammer features a smooth, firm push of recoil. Built with a non-removable carbon fiber PCP tank, it is engineered to deliver multiple regulated full-power shots before requiring a refill.
Overcoming the single-shot limitations of many big-bore designs, the Hammer utilizes a detachable 2-round magazine and a smooth straight-pull bolt action for quick follow-up shots. Featuring a world-class German-made barrel by Walther with a precision 1:24 twist, an ultra-light 2.5-pound trigger pull, a top Picatinny optic rail, and M-LOK handguard slots for lights and lasers, it is the ultimate field-ready platform for serious big-game hunters.
