Today’s air rifles aren’t just for killing soda cans, they’re legitimate, powerful game getters with a ton of features. Two of the top-tier examples on the market today come from Gamo: the Swarm Magnum Pro 8X GEN3i and the Swarm Viper 10X GEN3i air rifles. These aren’t kids’ toys — they’re adult precision air rifles meant for the field.
Both of these precision instruments can be had for around the $300 mark or less and are shockingly over-engineered. And just like firearms, the more you shoot these air rifles, the better you get. The best thing is, it’s much easier to practice more often with an air rifle than a centerfire or even rimfire rifle.
Now, let’s get into the guns.
Swarm Magnum Pro 8X GEN3i .25

The new Swarm Magnum Pro 8X GEN3i in .25 caliber brings serious power that’s ideal for small-game and pest control. Pushing alloy pellets at speeds up to 965 fps, it delivers impressive energy and penetration — enough to humanely dispatch rabbits, squirrels, and similar size game.
What really sets it apart is the inertia-fed 8-shot magazine: the rifle uses its own recoil to auto-index the next pellet. That means faster follow-up shots with no fumbling.
This air rifle isn’t built like a range plinker, it’s made like a hunting gun with rugged field use in mind. It incorporates automotive-grade, weather-resistant stock with a non-slip texturing on the grip and forend so it doesn’t get slick in wet conditions.
Gamo includes a 3-9×40 scope with the air rifle, which even features an adjustable trigger to fine tune this game-getting, pest killer.

The Swarm Magnum Pro 8X GEN3i balances power, convenience, and durability — an excellent all-around pellet rifle for small-game hunters who want serious performance without over-complication.

Gamo Swarm Viper 10X GEN3i

The Gamo Swarm Viper 10X GEN3i is built for hunters and shooters who demand speed, power, and versatility in a compact, multi-shot platform. Much like the Swarm Magnum, its patent-pending 10X GEN3i system and horizontal inertia-fed 10-shot magazine index pellets using recoil inertia, offering fast, reliable follow-up shots without the bulk of traditional multi-shot rifles.
Durability and comfort are central to the design: the automotive-grade, glass-filled nylon stock is weather-resistant and features rubber inserts on the forearm, grip, and cheek rest, ensuring a secure, comfortable hold in the field. The rifle’s Inert Gas Technology (IGT) piston delivers consistent power, reduces vibration, and improves overall longevity.

Noise is minimized through Gamo’s Whisper Maxxim sound suppression, routing pellets through dual chambers for quieter shooting, making it ideal for sensitive hunting areas or backyard pest control. The Recoil Reducing Rail compensates for nearly all recoil, protecting optics, while the CAT two-stage adjustable trigger provides a crisp, smooth pull for precise shots.
Compact yet capable, the Swarm Viper 10X GEN3i offers a perfect blend of speed, accuracy, and comfort, making it an excellent choice for small-game hunting, pest management, and versatile fieldwork.
