The soul of the Umarex Hammer is powered by air: 4,500 pounds per square inch of compressed air fill its on-board carbon fiber cylinder to a capacity of 24 cubic inches. The Hammer’s Lightspeed valve, coupled with a precision regulator instantly pulses a measure of air compressed to 3,000 psi, behind the projectile.

Umarex USA collaborated with PolyOne Corporation in the design, engineering and material selection for the stock of the Umarex Hammer air rifle. As a result, the stock, forearm and other key polymer components are produced from Nymax, an advanced polymer that withstands the rugged trials of outdoor hunting and shooting.
