Umarex Hammer .50 Caliber PCP Big Bore Hunting Rifle

The Umarex Hammer: Big Game Power Without the Powder

The Umarex Hammer represents a fundamental shift in modern hunting air rifles. This .50 caliber precharged pneumatic (PCP) rifle harnesses advanced engineering to deliver genuine big game performance—without the noise, recoil, or hearing protection requirements of traditional firearms.

Performance That Matters

The Hammer accelerates a 550-grain slug to 760 feet per second, generating 705 foot-pounds of muzzle energy. This is legitimate hunting power. The rifle operates on a 4500 psi fill pressure, with each shot regulated to 3000 psi, delivering three full-power shots plus a fourth shot at approximately 90% power from a single air cylinder fill.

What sets the Hammer apart is what it doesn't do: it produces minimal recoil—described as a firm push rather than a sharp kick—and operates quietly enough that hearing protection is unnecessary during hunting situations.
