Umarex Hammer First Shots with Rick from AirgunWEB

The Umarex Hammer is one serious big bore airgun.  Chambered in .50 caliber (.510 bore), the hammer can sling lead at over 700 FPE, and with the right ammo, get close to 800 FPE.  While other big bore airguns are all single shot, the Hammer is MULTI-SHOT utilizing a side shuttle 2 round magazine.

Cocking effort is well, effortless thanks to its patented valve and cocking system.  The trigger pull is light and consistent at well.  There’s a top rail for mounting optics and M-LOK slots in the forearm for mounting rails and other accessories.  The Umarex Hammer is powerful, accurate, lightweight, and also AFFORDABLE!.
