Swarm Magnum 10X GEN3i INERTIA FED caliber 10-shot air rifle

Description

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.

10X GEN3i INERTIA FED

Inertia fed. Market-leading design.
The 10X GEN3i system is the third generation of Gamo’s exclusive rapid-reload technology. This patent-pending design features a sleek, low-profile horizontal magazine that automatically advances using recoil inertia. The result is smoother breech loading, faster follow-up shots, and improved precision—all without manual indexing. This is state-of-the-art multishot performance, engineered by Gamo.

WHISPER FUSION NOISE REDUCTION

Gamo’s patented Whisper Fusion® technology delivers industry-leading sound suppression through a dual-chamber integrated moderator. As the pellet passes through two internal chambers, sound expansion is compressed and reduced, making this the quietest Gamo air rifle platform available.
While pellet choice affects sound output, Whisper Fusion significantly lowers perceived noise without compromising power—ideal for discreet hunting and pest control.

IGT MATCH1

The IGT Mach 1™ replaces the traditional spring with an advanced inert gas cylinder, featuring a massive 33mm piston for maximum power and efficiency. This system produces higher velocities, greater terminal penetration, smoother cocking, and reduced vibration.
If you demand more precision, less recoil, and true knockdown power, the IGT Mach 1 delivers.

CUSTOM ACTION TRIGGER

The C.A.T. (Custom Action Trigger) allows independent adjustment of both the first and second trigger stages. Shooters can fine-tune trigger travel and break to match their shooting style, resulting in improved control, consistency, and accuracy.

RECOIL REDUCING RAIL

Gamo’s Triple R Recoil Reducing Rail protects your scope from the intense recoil generated by high-powered air rifles. Its two-piece aluminum construction, separated by dual polymer struts, absorbs recoil shock and reduces stress on scope internals by nearly 100%.
The result: increased scope longevity, reduced vibration, and dead-on accuracy—shot after shot.
