This rifle marks the next evolution of the Swarm platform in .25 caliber, combining proven hunting heritage with advanced multi-shot innovation in a gamousa.com website-exclusive kit. The Swarm Power 8X GEN3i delivers outstanding knockdown magnum power and improved accuracy while offering smoother, more reliable operation for a superior shooting experience.
Featuring patent-pending 8X GEN3i Technology, the rifle integrates Gamo’s revolutionary horizontal inertia-fed magazine system into a lighter, more compact, low-profile design. The magazine indexes automatically using the inertia generated from recoil, creating a consistently smooth and precise breech-loading process that requires minimal effort from the shooter.
This kit includes two (2) 8-shot 8X magazines, a 3-9×40 scope and .25 Magnum Pellets.
Built for serious pest control and small-game hunters, the Swarm Power 8X GEN3i .25 Cal—available exclusively on gamousa.com—pairs hard-hitting .25 energy in a rugged, all-season air rifle.
The next evolution of the Swarm Magnum platform arrives in .25 caliber as a powerful, value-packed gamousa.com website-exclusive kit. Unprecedented knockdown magnum power meets next-gen multi-shot convenience, giving small-game hunters smoother operation, improved accuracy, and serious stopping power in one complete package.
This break-barrel rifle features patent-pending 8X GEN3i Technology, the horizontal inertia-fed magazine system that uses the rifle’s own recoil to auto-index the 8-shot magazine. The design is lighter, low profile, and engineered to create a consistently smooth and precise breech-loading process with every trigger pull.
The kit includes two GEN3i magazines so you can stay in the field longer without reloading. A premium 3-9×40 scope is paired to the rifle for bright, clear sight and confident shot placement at a wide range of distances. To complete the combo, you also receive a 200-count tin of .25 caliber Magnum lead pellets, optimized for expansion, deep penetration, and maximum energy transfer downrange.
The new stock design blends a classic hunting profile with automotive-grade glass-filled nylon for strength and durability. Non-slip texturing at the forearm, grip, and cheekpiece ensures outstanding control in any weather or terrain.
The pellet rifle is powered by Gamo’s most advanced technologies, including the smooth-shooting IGT Mach 1 gas piston and a high-capacity 33 mm cylinder that generates impressive energy with reduced vibration and more consistent velocities. The rifle is also equipped with Whisper Fusion sound-moderation technology, a dual-stage integrated suppressor that lowers muzzle noise while preserving accuracy. Together, Whisper Fusion, the 33 mm power cylinder, and IGT Mach 1 create a quieter, harder-hitting platform with long-term durability and a refined shot cycle that serious hunters will immediately appreciate.

*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.
