Description
The Swarm Power 8X GEN3i .25 caliber pushes the Swarm platform into true hunting territory, combining .25 caliber knockdown power with the speed of a multi-shot break barrel—available as a GamoUSA.com exclusive kit. The advantage of .25 cal is simple: you’re launching a heavier pellet with more downrange authority, which can mean better energy transfer, stronger knockdown performance, and more confidence on tough pests and small game when shot placement matters.
What makes this rifle stand out is how it pairs that .25-cal punch with patent-pending 8X GEN3i multi-shot technology. Gamo’s horizontal, inertia-fed magazine stays low for a compact, balanced feel, and it advances automatically using recoil inertia. In the real world, that means faster follow-up shots without breaking your rhythm—ideal when you get a second opportunity, need a quick correction, or have multiple targets moving through the same area.
This kit is ready to hunt right out of the box, including two (2) 8-shot 8X magazines, a 3–9×40 scope, and .25 Magnum pellets. It’s a practical setup for hunters who want a powerful .25 caliber pellet rifle but don’t want the slow pace of single-loading.
If your priority is maximum hit authority plus the real advantage of multi-shot speed, the Swarm Power 8X GEN3i .25 cal checks both boxes—hits harder, shoots faster, and stays streamlined for an all-season hunting and pest-control rifle.

8X GEN3i INERTIA-FED RAPID RELOAD
Eight quick shots in a sleek, low-profile setup. The GEN3i horizontal magazine advances with recoil inertia, keeping pellets lined up cleanly for smoother cycling and more consistent breech loading from the first shot to the last.
MAGNUM POWER IN .25 CALIBER
Designed for hard-hitting performance, this .25 caliber platform is rated up to 965 fps with alloy pellets, producing the kind of downrange energy that makes it a solid choice for pest control and small-game hunting.
IGT MACH 1 GAS PISTON + 33MM CYLINDER
Gamo’s IGT Mach 1 powerplant swaps the standard spring for a gas-piston system, and its 33mm cylinder is built for higher output with a cleaner, more controlled shot cycle—exactly what you want from a high-power break-barrel air rifle.
WHISPER FUSION NOISE SUPPRESSION
Whisper Fusion is GAMO’s top-level sound-moderation system, built to quiet the shot by controlling how air expands and exits the muzzle through a multi-stage design.
C.A.T. INDEPENDENTLY ADJUSTABLE TRIGGER
Gamo’s two-stage C.A.T. trigger lets you adjust each stage separately, so you can dial in the take-up and break to fit your shooting style—helping improve control, consistency, and real-world accuracy.
FIELD-READY THUMBHOLE STOCK + INCLUDED SCOPE
The field-ready thumbhole stock is built for steady, confident shooting in real hunting conditions. Its ergonomic thumbhole design promotes a more natural trigger-hand position and better control through the shot, while the textured grip areas help keep the rifle planted when you’re wearing gloves or dealing with wet weather. Paired with the included Gamo 3-9×40 scope, you can set up quickly and start reaching out with a clearer sight picture and more precise shot placement—making this a ready-to-hunt package right out of the box.
