Built for stealthy hunting and accurate shot placement, the Gamo Whisper Fusion Mach 1 air rifle is a leader in quiet shooting. Outfitted with a 3-9x40 scope, it's a hunter's dream when it comes to quiet, precise shooting. Equipped with the Whisper Fusion sound moderator, the Whisper Fusion Mach 1 is the most discreet air rifle Gamo offers. Combine that with the enhanced IGT Mach 1 powerplant, and you experience faster velocity, more power and even better precision. By using a gas cylinder versus a conventional spring, air rifles furnished with the IGT Mach 1 offer smoother cocking and shooting, no spring torque, no spring fatigue, no issues shooting in cold weather, and a much longer life than a spring powered gun. The IGT Mach 1 allows you to cock the gun and wait before taking your next shot without worrying about any weakening of the metal spring. You'll also notice a lot less twang and vibration.
