Umarex Hammer Air Rifle

Umarex Hammer Air Rifle with more than 700 ft-lbs of energy. That’s in the same ballpark as the .44 Magnum.

 Umarex USA designed and now manufacturing a .50 caliber air rifle called the Hammer. For those that think air rifles are just toys for for squirrels only, this rifle will launch a 550 grain lead slug at about 760 fps. That works out to be more than 700 ft-lbs of energy. That’s in the same ballpark as the .44 Magnum. Lighter loads go faster, of course. The 180 grain ARX projectile will hit about 1,100 fps.

 Umarex uses a straight pull bolt that needs only 2 pounds of cocking pressure. The air tank holds 4,500 psi of compressed air. The trigger pull is set at 3 pounds. The gun uses a Magpul pistol grip and has M-LOK attachment points for accessories.

 It is currently out of stock, but you can register here for an update when the rifle will be available.
