Gamo Swarm Viper 10x Gen3i .177 Caliber Air Rifle with Scope$253.53
Availability: In Stock
The Gamo Swarm Magnum Pro Gen3i is a .177 caliber air rifle built around Gamo's latest rapid-fire autoloading system—the 10X Gen3i technology. If you're after a modern airgun that lets you stay on target without fumbling with manual loading between shots, this rifle brings real engineering to the backyard and small-game hunting space. The Gen3i system uses inertia feedback from each shot to automatically index the next pellet into the breech, so you get smooth, hands-off magazine cycling that keeps your rhythm consistent and your aim unbroken.
Built on Gamo's IGT Mach 1 inert gas technology, the Swarm Magnum Pro Gen3i harnesses a 33 mm gas piston powerplant—the kind of pneumatic backbone that gives you repeatable shot-to-shot velocity and minimal maintenance compared to spring-piston guns. The trigger is a two-stage CAT (Custom Action Trigger) design with independent adjustment on each stage, so you can tune the break weight and pre-travel to your preference and shooting style. That level of control matters when you're dialing in a rifle for precision or hunting applications.
This is a rifle for serious airgunners and hunters who want to move past single-shot accuracy work and take advantage of ten-shot capacity without breaking focus between shots. The inertia-fed magazine integration keeps the design clean and balanced, and the whole platform is built to reward consistent shooting. Whether you're zeroing in a backyard range or pursuing small game, the Gen3i's semi-automatic workflow and tunable trigger give you the tools to shoot your best.
| Caliber | .177 |
| Action Type | 10X Gen3i Auto-Loading Technology |
| Magazine Feed | Inertia Fed |
| Powerplant | IGT Mach 1 Inert Gas Piston |
| Cylinder Size | 33 mm |
| Trigger | Two-Stage Custom Action Trigger (independently adjustable) |
| Capacity | Ten shots |
The Gen3i uses inertia force generated by the recoil of each shot to automatically advance the next pellet from the magazine into the breech. No manual cocking or lever operation is needed between shots—the recoil itself handles the indexing, letting you stay focused on aiming and shooting.
The IGT Mach 1 inert gas piston replaces a traditional spring mechanism. It's sealed and pre-charged, which means more consistent shot velocity over time, less maintenance, and reduced wear compared to spring-piston designs. It's a more refined platform for accurate, repeatable shooting.
Yes. The two-stage CAT trigger allows independent adjustment of both the pre-travel (slack before engagement) and the break weight (force needed to fire). This gives you the ability to tune the trigger to your preference and shooting style.
This rifle is designed for hunters pursuing small game and shooters who want repeatable, rapid-fire accuracy without manual reloading. The ten-shot autoloading capacity and tunable trigger make it well-suited to backyard target work and hunting applications where staying on target across multiple shots matters.
