Gamo Swarm Viper 10X Gen3i Break-Barrel Air Rifle – .177 Caliber

The Gamo Swarm Viper 10X Gen3i is a break-barrel spring-piston air rifle chambered in .177 caliber, designed for pest control, small game hunting, and extended plinking sessions. The Gen3i designation indicates Gamo's third-generation 10-shot rotary magazine system, which allows for rapid follow-up shots without manual reloading between pellets. This spring-powered platform requires no CO2 or external air source—just break the barrel, load the magazine, and shoot.

The rifle features a synthetic all-weather stock with textured grip panels and an integrated suppressor to reduce muzzle report. The 10X Quick-Shot magazine feeds .177 pellets reliably, and the system is compatible with standard lead pellets in the 7.0–10.5 grain range. The adjustable two-stage trigger and fiber optic sights provide solid baseline accuracy, with a dovetail rail for mounting optics. Expect velocities up to 1,300 fps with lightweight alloy pellets, though accuracy typically peaks with mid-weight lead rounds in the 900–1,000 fps range.
