This is the next generation Swarm air rifle. It features Gamo’s most powerful technologies, the 33 mm cylinder and the IGT Mach 1, allowing it to deliver next-level power with 1,650 fps in .177 caliber. That combined with our patent-pending 10X Gen2 inertia fed technology and the Whisper Fusion technologies, makes the Gamo Swarm Magnum 10X GEN2 a revolutionary break barrel. Every Swarm Magnum 10x GEN2 .177 multishot pellet air rifle includes a 10-shot magazine.  It also includes a Gamo 3-9×40 scope (with a one piece mount).  This .177 caliber break barrel air rifle provides accuracy and high velocity – ideal for plinking, and also for nuisance animals such as mice, rats, birds and snakes.
