This is the next generation Swarm multishot pellet air rifle. This .22 multishot pellet air rifle features Gamo’s most powerful technologies, the 33 mm cylinder and the IGT Mach 1, allowing it to deliver next-level power with 1,300 fps in .22 caliber. That combined with Gamo's patent-pending 10X GEN3i inertia fed technology and the Whisper Fusion technologies, makes the Gamo Swarm Magnum 10X GEN3i a revolutionary break barrel.

The magazine indexes using the inertia force from the recoil of the air rifle—creating a smoother and more precise breech loading process. This is Gamo. This is state-of-the-art rapid-reload technology. The IGT Mach 1 33mm cylinder power plant allows it to deliver next-level power with 1,300 fps in .22 caliber.

Every Swarm Magnum 10x GEN3i .22 multishot pellet air rifle includes 10-shot magazine. This .22 caliber break barrel air rifle delivers accuracy with high energy downrange for ultimate impact and penetration, ideal for small game such as rabbits, squirrels, raccoons, and crows.


  • Inertia fed. Market leading design. Introducing the third generation of Gamo’s exclusive rapid-reload technology. This patent-pending 10X GEN3i technology features a sleek and stylish design combined with our horizontal inertia fed magazine integration. The magazine indexes using the inertia force from the recoil of the air rifle—creating a smoother and more precise breech loading process. This is Gamo. This is state-of-the-art rapid-reload technology.


  • Gamo’s patented Whisper technology leads the air rifle industry in sound suppression. This technology is categorized into three tiers—Whisper, Whisper Maxxim and Whisper Fusion—for quiet, quieter, and quietest performance. However,“noise reduction” does not mean “silence,” as sound levels will vary depending upon pellet choice. A lighter, faster and smaller caliber pellet, for instance, will produce a louder sound than a heavier, slower and higher caliber pellet. To further assist with your purchasing decision, please refer to the chart above.
  • The Whisper® Fusion® technology incorporates a double integrated sound moderator making it the quietest Gamo air rifle. The pellet travels through two different chambers, compressing and preventing the noise expansion.


  • Based off the groundbreaking IGT platform, the IGT MACH 1™ replaces the standard spring power plant with an Inert Gas Cylinder, but the IGT MACH 1’s monster 33 millimeter cylinder delivers more velocity and terminal penetration. The pneumatic cylinder rockets pellets up to 1300 Feet Per Second (fps) in .22 caliber (with Alloy Ammunition), and promotes smooth and consistent cocking efforts with constant power delivered to any pellet you shoot. If you want: More Precision, Less Vibration and True Knock Down Power. Make sure your next Gamo has the IGT MACH 1 inside.


  • The revolutionary C.A.T. (Custom Action Trigger) enables Gamo air rifle owners to independently adjust the 1st and 2nd stages of their trigger to tailor the trigger pull and crispness to their personal preference. Simply loosen the 1st stage adjustment screw and the trigger travel increases. If a shorter travel length is desired just tighten the same screw to decrease the 1st Stage travel length. The 2nd Stage Adjustment is made justas easily —unscrew the adjustment setting to increase the 2nd Stage travel length or decrease it by screwing in the same adjustment point.


  • Gamo, pioneering the latest air gun technology, delivers the groundbreaking Triple R(Recoil Reducing Rail).The RRR was developed to subdue the taxing stresses placed on your scope from the intense recoil of air guns and high-powered rifles. The Recoil Reducing Rail uses patent pending two-piece aluminum construction separated by dual polymer struts to absorb the shockwaves generated by the recoil.
  • Once the scope is mounted to the Recoil Reducing Rail, the recoil stresses to its internal components are reduced by almost 100%. Hunters demand: Scope Reliability, Reduced Vibration and Dead On Accuracy. The Triple R (Recoil Reducing Rail) — Preserve Your Scope’s Lifetime for the Next Time. Only from Gamo.
