Gamo Swarm Magnum Pro G3i Inertia Features The Gamo USA Swarm Magnum Pro G3i Inertia uses the company s patent pending 10X GEN3i technology a horizontal inertia fed magazine system that indexes a fresh pellet into the breech using the recoil force generated by each shot. This creates a smoother more precise loading cycle compared to earlier break barrel single shot designs allowing for rapid follow up shots without manually cycling the action. The 10 round magazine keeps the rifle fed through extended pest control or plinking sessions without constant reloading. Driving all of this is Gamo s IGT Mach 1 inert gas piston powerplant built around a 33mm cylinder that delivers consistent velocity shot after shot while reducing the recoil and noise typical of coiled spring designs. A two stage CAT trigger independently adjustable for a shooter s preference breaks consistently to support accurate pellet placement at distance. The 21 inch barrel combined with the IGT Mach 1 system pushes .22 caliber pellets to speeds of up to 1300 feet per second giving the rifle plenty of authority for small pest control tasks. A synthetic stock keeps the rifle lightweight and weather resistant for outdoor use in varying conditions. Topped with an included Gamo 3-9x40 scope the Swarm Magnum Pro G3i Inertia is ready to shoot out of the box making it a complete package for shooters who want a fast cycling accurate air rifle without sourcing separate optics.
