The Gamo Swarm Magnum 10X GEN3i is the next generation of Gamo’s multi-shot break-barrel design in .22 caliber. Its inertia-fed horizontal magazine indexes using recoil for smooth, precise cycling and a lower profile. The IGT Mach 1 gas piston (33 mm) delivers serious energy and reduced vibration, while Whisper Fusion moderates report. A CAT two-stage adjustable trigger, SWA recoil pad, and RRR 11 mm rail paired with the included Gamo 3–9×40 scope round out a powerful small-game and pest-control platform.
Always follow federal, state and local laws and practice safe handling. Intended for legal sporting use only.
