The next generation Swarm 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; SWA (Shock Wave Absorber) Recoil pad with up to 74% recoil absorption and a non-slip texture design on grip and forearm. That combined with our patent-pending 10X Gen3 inertia fed technology and the Whisper Fusion technologies, makes the Gamo Swarm Magnum 10X GEN3 a revolutionary break barrel.
