The Gamo Swarm 10 X Viper Geni3 Multi Shot .22 Caliber Air Rifle with Scope works great for pest control and hunting. The Inert Gas Technology (IGT) gas piston increases accuracy and durability, and the Whisper Maxxim sound dampening technology compresses and prevents noise expansion. The 10-shot horizontal inertia fed magazine integration helps you easily reload, and the GAMO’s CAT (Custom Action Trigger) delivers a crisp trigger pull.
