Gamo Swarm Magnum Pro G3i Inertia Features The Gamo Swarm Magnum Pro G3i Inertia is built around Gamo s third generation 10X GEN3i rapid-reload technology a patent-pending system that indexes the horizontal magazine using the inertia force generated by the rifle s own recoil. This inertia-fed design creates a smoother more precise breech loading cycle than earlier spring-piston magazine systems reducing the chance of feed issues shot after shot. Launching .177 caliber pellets at up to 1650 feet per second the Swarm Magnum Pro delivers flat-shooting performance suited to pest control and small game hunting at extended distances. The 21-inch barrel and synthetic stock keep the rifle balanced and steady when shooting from field positions. The rifle ships complete with a Gamo 3-9x40 scope giving the shooter a ready-to-use magnified optic without needing to source and mount glass separately. This pairing lets new owners get on target quickly whether sighting in at the range or heading straight into the field. The 10-round magazine capacity minimizes reloading interruptions during an active pest control session or hunting outing. Combining Gamo s proven inertia-fed reload system with an included scope the Swarm Magnum Pro G3i Inertia offers a complete ready-to-shoot air rifle package for hunters and shooters alike.
