This is the next generation Swarm Magnum pellet rifle. Unprecedented speed and power. Unparalleled performance. Offering smoother operation and improved accuracy for an outstanding shooting experience, the Swarm Magnum Pro 10X GEN3i includes the patent-pending 10X GEN3i Technology with our revolutionary new horizontal inertia fed magazine integration, making it lighter, more compact and low profile. The magazine indexes using the inertia force from the recoil of the air rifle – creating a smoother and more precise breech-loading process. This air rifle features a new stock that combines a traditional hunting stock design with the automotive grade glass filled nylon materials. Forearm, grip and cheek piece are non-slip texturized.
The GAMO Swarm Magnum Pro 10X GEN3i Pellet Rifle represents the next evolution in high-power multishot break barrel air rifles, delivering exceptional speed, power, and precision. Designed for serious shooters, hunters, and pest control applications, this advanced air rifle offers smoother operation, improved accuracy, and faster follow-up shots for an unmatched shooting experience.
At the heart of the Swarm Magnum Pro is the patent-pending 10X GEN3i horizontal inertia-fed magazine system, engineered to be lighter, more compact, and lower profile than previous designs. The magazine automatically indexes using the rifle’s recoil energy, creating a smoother, more precise breech-loading process and enabling rapid multishot performance without manual reloading.
The rifle features a newly designed traditional hunting-style stock, constructed from automotive-grade glass-filled nylon for durability and all-weather performance. Non-slip texturized panels on the forearm, grip, and cheek piece provide enhanced comfort, control, and stability in the field.
Powered by GAMO’s most advanced technologies—including the oversized 33 mm cylinder and the IGT™ Mach 1 gas piston—the Swarm Magnum Pro delivers extreme power, reaching up to 1,300 fps in .22 caliber and 1,650 fps in .177 caliber (with alloy pellets). When combined with Whisper Fusion sound suppression technology, this rifle offers magnum-level performance with reduced noise and vibration, making it a true breakthrough in break barrel air rifle design.
Every Swarm Magnum 10x GEN3i Pro multishot pellet air rifle includes 10-shot magazine. It also includes a Gamo 3-9×40 scope (with a one piece mount). This break barrel air rifle delivers accuracy with high energy downrange for ultimate impact and penetration, ideal for small game such as rabbits, squirrels, raccoons, and crows.
The 10X GEN3i™ inertia-fed magazine system represents the third generation of GAMO’s exclusive rapid-reload technology. Featuring a sleek, low-profile horizontal magazine design, this patent-pending system automatically indexes pellets using the recoil energy of the air rifle. The result is faster follow-up shots, smoother breech loading, and uninterrupted shooting without manual reloading. Lighter, more compact, and precision-engineered, 10X GEN3i sets the benchmark for multishot break barrel air rifles.
GAMO’s Whisper Fusion® sound suppression system delivers industry-leading noise reduction for powerful air rifles. As the quietest tier in the Whisper family—Whisper, Whisper Maxxim, and Whisper Fusion—this advanced system uses a dual integrated sound moderator to significantly reduce muzzle noise. Pellets pass through two separate expansion chambers that compress and slow escaping air, minimizing sound output while maintaining performance. Noise levels may vary depending on pellet type, but Whisper Fusion provides exceptional quiet shooting for hunting and backyard use.
The IGT™ Mach 1 gas piston system replaces traditional steel springs with an inert gas cylinder for smoother operation, reduced vibration, and consistent power delivery. Built around a massive 33 mm cylinder, IGT Mach 1 produces extreme velocity and terminal performance—reaching up to 1,300 fps in .22 caliber and 1,650 fps in .177 caliber (with alloy pellets). This advanced power plant delivers improved accuracy, smoother cocking, and serious knockdown power for demanding shooters.
The CAT™ two-stage adjustable trigger allows shooters to fine-tune both the first and second stages independently. Adjust trigger travel and break to match your shooting style for a crisp, clean pull and enhanced accuracy. Whether you prefer a lighter or more deliberate trigger feel, the CAT system provides precise control and confidence with every shot.
This air rifle features a traditional hunting-style stock constructed from automotive-grade glass-filled nylon for exceptional strength and all-weather durability. Non-slip texturized surfaces on the forearm, grip, and cheek piece improve handling, comfort, and control—ensuring stability and confidence in any shooting condition.
The RRR™ Recoil Reducing Rail is engineered to protect optics from the intense recoil of high-powered air rifles. This patent-pending system uses a two-piece aluminum rail with dual polymer shock absorbers to dramatically reduce vibration and recoil stress on mounted scopes—by up to 99.9%. The result is improved scope longevity, maintained zero, and consistent accuracy shot after shot. Designed for hunters who demand reliability and precision.

*Manual Safety: The manual safety is the lever that is in front of the trigger, if you pull it forward, the safety is off, if you pull it backwards (towards the trigger), the safety is on. Please make sure you do not turn the safety off until you are ready to shoot.
Automatic Cocking Safety System: The automatic safety cocking system is a different safety feature than the Manual Safety; it does not allow you to pull the trigger while cocking the air rifle. When you break the barrel this safety system is engaged and when you put the barrel back into position this safety system is disengaged.
Please read the manual before using.
