WHISPER FUSION MACH 1 AIR GUN WITH COMBO PACK OF PELLETS The GAMO Whisper Fusion is powerful, quiet and accurate. The IGT MACH 1 gas piston delivers higher muzzle velocity, less vibration and smoother cocking. It also features Whisper Fusion technology, the quietest noise reduction technology patented by Gamo. 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 gun 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 gun quiet, powerful and accurate, and it does not produce intense vibration like a traditional spring piston. It is equipped with a Gamo 3-9×40 scope. The synthetic stock has a comfortable, ambidextrous cheek piece. The Gamo Whisper Fusion Mach 1 also features a CAT that allows you to adjust the 1st and 2nd stage to your preference. It also has the Recoil Reducing Rail (RRR) that absorbs the recoil and reduces the stress on the scope by almost 100 percent.
