Ideal for any level shooter, the Viper IGT Air Rifle comes fully loaded. It starts with Inert Gas Technology (IGT) that shoots pellets using a pneumatic inert gas cylinder in place of conventional spring systems. The advantage includes extreme durability; more accuracy and precision; and steady, consistent power. Without spring friction, the cocking effort is more constant and smooth. Combining Whisper technology with an integrated noise dampener ND52, this break-action air rifle delivers more velocity and terminal penetration, while producing less noise and vibration. Shock Wave Absorber recoil pad provides enhanced shock absorption. 3-9x40WR Gamo scope included. One-piece solid scope mount. Comes in a durable all-weather black synthetic stock with rubber grip panels on the forearm and grip.Caliber: .177.Length of pull: 14-1/4.Cocking effort: 30 lbs.Barrel length: 18.Overall length: 46.Weight: 5.3 lbs.
