The umarex airsaber uses high-pressure air to propel a 376-grain arrow at velocities up to 450 feet per second with a fully charged air tank.Arrows shot from a full tank reach energy levels over 169 ft-lbs.This is more than enough for hunting big game and is, in fact, legal in 10 states for deer and most states allow for predator/feral species hunting with devices of this kind.The airsaber uses a special carbon-fiber arrow that weighs 276 grains by itself.These arrows accept standard and mechanical broadheads and are easily changed out.Oal: 41"Action: BoltCaliber: Umarex Straight Flight Technology ArrowsCapacity: 1rdSights: Optic ReadyWeight: 6.30 lbs
