Swarm Magnum Pro
Powerful 5.5 mm configuration with a 10-shot automatic feeding system

Swarm Magnum Pro 10X GEN3i combines traditional break-barrel cocking with an inertial magazine system that prepares the next pellet for loading. It preserves the self-contained simplicity of a break-barrel rifle while reducing the need to insert a pellet manually after every shot.

10X GEN3i Inertial Magazine
Third-generation low-profile multi-shot system
10XGEN3i Inertia Fed Magazine

The magazine uses recoil inertia to index for the next loading cycle.

How does GEN3i work?

When the barrel is broken and cocked, the system feeds one pellet into the barrel. The magazine indexes after the shot through the inertia generated by recoil, preparing the following pellet for the next cocking cycle.

This design is intended to provide a smooth loading sequence while keeping the magazine compact and low above the action.

5.5 mm magazine: Gamo reference 6212644. One magazine is confirmed in the standard package.
IGT Mach 1
Gas piston instead of a conventional steel mainspring

Swarm Magnum Pro uses the IGT Mach 1 powerplant. It replaces the conventional coiled mainspring with Gamo's gas-piston system and forms the high-output Magnum configuration of this model.

IGT

M1
Mach 1

BB
Break Barrel

Whisper Fusion
Integrated sound-moderating barrel system

Gamo equips the model with Whisper Fusion, its integrated sound-moderating system incorporated into the barrel assembly and listed as part of the official Swarm Magnum Pro 10X GEN3i configuration.

Please note: Whisper Fusion reduces the sound signature but does not make the rifle silent. Perceived noise also depends on output, pellet choice and the shooting environment.

The combination of 45 J, 10X GEN3i, IGT Mach 1 and the included 3-9×40 optic places this model above Gamo's standard lower-output multi-shot break-barrel platforms. It is intended for controlled recreational and sporting target use in a safe and legally permitted environment.

High-output air rifle: 45 J is substantial energy for an air rifle. Always use a reliable backstop, suitable eye protection and a safe shooting area, and comply with all applicable rules regarding possession, registration, transport and use.
