The TalonP sets a new standard in air pistol power levels. The Direct-Flo Valve delivers over 50ft. lbs. of energy with a .25 caliber hunting pellet. This pistol is for the serious hunter wanting a compact, yet powerful hunting tool Spin-Loc spare tank systems provide you with the ability to fill the Spin-Loc tanks directly from a standard quick disconnect without removal of the air tank from the gun. The lack of need to remove the air tank for recharging has allowed us to also install a pressure gauge. Rifles with scope include a 3-9x 50 mil-dot variable power scope.FeaturesLothar Walther BarrelLightweightRecoillessPressure Relief DeviceAdjustable PowerSpin-Loc TankMultiple Mounting RailsAir Tank Volume: 213 cc
