Gamo Swarm Magnum Pro 10X Gen3i 4.5mm Air Rifle

Keep your attention on the next shot. The Swarm Magnum Pro 10X Gen3i carries ten pellets in a low-profile horizontal magazine. Its inertia-driven indexing system advances the magazine during the firing cycle; you still break and recock the barrel for each shot.

Built around the Gen3i system

An IGT Mach 1 gas piston powers the rifle, while the Whisper Fusion barrel system, CAT trigger and Recoil Reduction Rail complete the setup. The glass-filled nylon stock has textured grip, forearm and cheekpiece surfaces.
