Gamo Swarm Magnum G2_-. The Gamo Swarm Magnum G2 Air Rifle with Scope provides unprecedented speed and power and unparalleled performance. Offering smoother operation and improved accuracy for an unprecedented shooting experience, the all-new Swarm Magnum 10X GEN 2 includes the patent-pending 10X GEN 2 Technology with their revolutionary new horizontal, internal inertia fed magazine integration, making it lighter, more compact and low profile. The rifle comes stock with a dovetail mounted scope.

The pellet travels through two different chambers, compressing and preventing the noise expansion.
