The Gamo Swarm Viper 10X Gen3i is a .177 break-barrel pellet rifle built around a 10-shot horizontal magazine that re-indexes itself from the rifle's own recoil, so you break the barrel, fire and keep shooting without reloading each pellet. A gas-piston powerplant (IGT) replaces the steel spring, which smooths vibration and keeps power steadier over long sessions, and the Whisper Maxxim baffle system takes the bark out of the shot. A two-stage adjustable CAT trigger and a recoil-absorbing scope rail round out a package aimed at plinkers and small-game hunters who want fast follow-up shots. Against single-shot break barrels it trades a little simplicity for speed; against PCP rifles it gives up easy accuracy and a light trigger but needs no pump, tank or fill gear.

Owners rate it around 4.1 out of 5. They like the self-indexing magazine and the quieter, smoother gas-piston shot, and most call it good value for a scoped multi-shot break barrel. Complaints center on cocking effort, the real-world velocity gap versus the 1,300 fps claim, and the need to test several pellets before groups tighten up.
The Gamo Swarm Viper 10X Gen3i is a .177 caliber break-barrel pellet rifle that comes with a scope. It uses an inertia-fed, 10-shot horizontal magazine. The recoil of each shot automatically indexes the magazine, so you can break the barrel, fire and follow up quickly.
A gas piston powered by Inert Gas Technology (IGT) delivers steady power and reduces vibration. Whisper Maxxim sound dampening guides the pellet through two chambers to contain sound expansion for a quieter shot. The Custom Action Trigger (CAT) is a two-stage adjustable trigger. The Recoil Reducing Rail absorbs 99.9% of recoil to protect the scope.
The stock is automotive-grade synthetic, with rubber grip inserts in the forearm, grip and cheekpiece. The rifle reaches speeds of up to 1,300 fps with .177 caliber alloy pellets. It is intended for pest control and hunting.
