Inertia fed. Market leading design. Introducing the third generation of Gamo's exclusive rapid-reload technology. This patent-pending 10X GEN3i technology features a sleek and stylish design combined with our horizontal inertia fed magazine integration. The magazine indexes using the inertia force from the recoil of the air rifle-creating a smoother and more precise breech loading process. This is Gamo. This is state-of-the-art rapid-reload technology. The IGT (Inert Gas Technology) gas piston allows it to deliver next-level power with 1,000 fps in .22 caliber.
