Gamo Swarm Magnum 10X 'GEN3i' INERTIA FED .177 Caliber Air Rifle with Scope

The Gamo Swarm Magnum 10X GEN3i represents the next evolution of the 10-shot inertia fed pellet air rifle. Designed for shooters who demand speed, power, and precision, this multishot break barrel air rifle combines Gamo’s most advanced technologies into one formidable platform.

At its core is the IGT Mach 1™ gas piston with a massive 33mm cylinder, delivering exceptional velocity, downrange energy, and consistent shot-to-shot performance. Capable of firing pellets at up to 1,300 FPS in .22 caliber or 1,650 FPS in .177 caliber, the Swarm Magnum is built for serious hunting and pest control applications.

What truly sets this rifle apart is Gamo’s patent-pending 10X GEN3i inertia fed technology. Unlike traditional multishot systems, the horizontal magazine uses the rifle’s recoil to automatically index each pellet. The result is a faster, smoother, and more precise loading process—allowing rapid follow-up shots without sacrificing accuracy.

Paired with Whisper Fusion® noise-reduction technology, this powerful air rifle remains remarkably quiet for its class, making it ideal for backyard pest control or small-game hunting. Each Swarm Magnum 10X GEN3i includes a 10-shot magazine and a Gamo 3-9×40 scope with a one-piece mount, providing everything needed for accurate shooting right out of the box.

Delivering high energy, deep penetration, and consistent accuracy, this 10-shot inertia fed pellet air rifle is perfectly suited for hunting small game such as rabbits, squirrels, raccoons, and crows.

Every Swarm Magnum 10x GEN3i Inertia Fed .22 multishot pellet air rifle includes  10-shot magazine.
