Gamo Swarm Magnum Pro GEN3 4.5mm / .177 Multi-Shot Gas Piston Air Rifle

The Gamo Swarm Magnum Pro GEN3i 4.5mm Air Rifle delivers extreme power, rapid follow-up shooting, and advanced multi-shot technology for shooters demanding top-tier airgun performance. Built around Gamo’s revolutionary 10X GEN3i system, this high-performance air rifle offers smoother cycling, improved loading reliability, and exceptional shooting precision in a lighter and more compact platform.

At the heart of the rifle is the patent-pending 10X GEN3i horizontal inertial-fed magazine system. Using the recoil force generated during shooting, the magazine automatically indexes for seamless pellet cycling and a more precise breech-loading process. Combined with Gamo’s powerful IGT Mach 1 gas piston technology, the Swarm Magnum Pro produces an impressive 36 Joules of energy and velocities up to 470 m/s in 4.5mm caliber.

The Whisper Fusion sound moderation system helps reduce noise while maintaining performance, making the rifle more comfortable to shoot. The newly designed stock blends classic hunting rifle ergonomics with durable automotive-grade glass-filled nylon construction, providing excellent strength and weather resistance. Textured grip surfaces on the forearm, grip, and cheekpiece ensure secure handling in all conditions.

For enhanced shooting accuracy, the rifle includes a Gamo 3-9×40 WR1PM scope and features the RRR™ Recoil Reducing Rail to protect optics from recoil stress. The adjustable CAT™ trigger allows shooters to customize trigger feel for improved control and consistency.

Designed for serious target shooters and airgun enthusiasts, the Gamo Swarm Magnum Pro GEN3i combines cutting-edge technology, massive power, and rapid multi-shot capability in one advanced air rifle platform.
