The GAMO Swarm Fusion 10X GEN3 is the second generation of our Swarm technology, featuring a horizontal magazine integration and open sights making the Swarm Fusion lighter, more compact and lower profile. The third generation 10X offers a smoother operation and improved accuracy. Simply break the barrel and fire for lightning-quick follow-up shots. This air rifle also features Whisper Fusion sound dampening, the quietest noise reduction technology patented by GAMO. The pellet goes through two different chambers, compressing and preventing noise expansion. The Inert Gas Technology (IGT) gas piston delivers steady and consistent power, increasing accuracy and durability with less vibration. This pellet rifle incorporates GAMOs CAT (Custom Action Trigger), a two-stage adjustable trigger that provides a crisp, clean and smooth trigger pull for improved accuracy.
