The Gamo Whisper Fusion Mach 1 is equipped with an IGT Mach 1 power plant, the most powerful gas piston technology from Gamo. It shoots a pellet at up to 1020 fps thanks to the larger 33mm cylinder. This air rifle also features Whisper Fusion sound dampening, the quietest noise reduction technology patented by Gamo. The pellet goes through two different chambers, compressing and preventing noise expansion. Combining the Whisper Fusion and IGT Mach 1 technologies makes this rifle quiet, powerful and accurate, and it does not produce intense vibration like a traditional spring piston. It is equipped with a Gamo 3-9x40 scope. The synthetic stock has a comfortable, ambidextrous cheek piece. The Gamo Whisper Fusion Mach 1 also features a CAT (Custom Action Trigger) that allows you to adjust the 1st and 2nd stage to your preference. It also has the Recoild Reducing Rail (RRR) that absorbs the recoil and reduces the stress on the scope by almost 100%. 5 year warranty. Features: Single cocking system SWA (shock wave absorber) recoil pad with up to 74% recoil absorption Non-slip texture design on grip and forearm
