10X GEN3i Inertia Fed Magazine

Inertia fed. Market leading design. Introducing the third generation of Gamo’s exclusive rapid-reload technology. This patent-pending 10X GEN3i technology features a sleek and stylish design combined with our horizontal inertia fed magazine integration. The magazine indexes using the inertia force from the recoil of the air rifle—creating a smoother and more precise breech loading process. This is Gamo. This is state-of-the-art rapid-reload technology. The IGT Mach 1 33mm cylinder power plant allows it to deliver next-level power with 1,650 fps in .177 caliber.

IGT Mach 1

The IGT MACH 1 is based on a monster 33 millimeter cylinder that makes it deliver more velocity and terminal penetration. The pneumatic cylinder rockets pellets up to 1300 Feet Per Second (fps) in .22 caliber (with Alloy Ammo). If you want: More Precision, Less Vibration and True Knock Down Power. Make sure your next Gamo has the IGT MACH 1 inside.

10X GEN3i Inertia Fed Magazine 10 shot air rifle technology

This patent-pending 10X GEN3i technology includes our revolutionary horizontal inertia fed magazine integration, making it lighter, more compact and low profile. This upgraded rapid reload technology makes the magazine rotate and inserts a pellet into the breech using the inertia of the recoil when shooting the air rifle. The third generation 10X offers smoother operation and improved accuracy.

Whisper Fusion, the quietest noise reduction technology from Gamo

The Whisper Fusion technology incorporates a double integrated sound moderator making it the quietest Gamo air rifle. The pellet travels through two different chambers, compressing and preventing the noise expansion.

CAT Trigger, independently adjust 1st and 2nd stages

The CAT (Custom Action Trigger) features two screws so you can independently adjust the 1st and 2nd Stages of the trigger. Tailor Your Trigger To How You Want.

Recoil Reducing Rail

When you purchase the Gamo Swarm Magnum 10X GEN3i, the air rifle comes with the Recoil Reducing Rail, a patent pending technology from Gamo: two-piece aluminum construction rail separated by dual polymer struts to absorb the shock waves generated by the recoil. Once mounted to the Recoil Reducing Rail, the recoil stresses to internal components of the scope are reduced by almost 100%.

Though All-Weather Thumbhole Synthetic Stock

The synthetic stocks from Gamo are glass filled nylon stocks from the suppliers who provide those materials to high end European car manufacturers. Our stocks are carefully designed to fit the shooter and to align perfectly with the scope. They are all-weather, tough, and lightweight.

Gamo 3-9x40 Scope included

Gamo 3-9x40 shockproof and fogproof scope with mounts. Designed for maximum accuracy and reliability.

SWA (ShockWave Absorber) Recoil Pad

Adjustable air rifle shock absorber with three removable absorption cells. Shoot comfortably.

This is the next generation Swarm multishot pellet air rifle. This .177 multishot pellet air rifle features Gamo’s most powerful technologies, the 33 mm cylinder and the IGT Mach 1, allowing it to deliver next-level power with 1,650 fps in .177 caliber. That combined with our patent-pending 10X GEN3i inertia fed technology and the Whisper Fusion technologies, makes the Gamo Swarm Magnum 10X GEN3i a revolutionary break barrel. Every Swarm Magnum 10x GEN3i .177 multishot pellet air rifle includes 10-shot magazine. It also includes a Gamo 3-9×40 scope (with a one piece mount). This .177 caliber break barrel air rifle delivers accuracy with high energy downrange for ultimate impact and penetration, ideal for small game such as rabbits, squirrels, raccoons, and crows.

Whisper Fusion Noise Reduction
Gamo’s patented Whisper technology leads the air rifle industry in sound suppression. This technology is categorized into three tiers—Whisper, Whisper Maxxim and Whisper Fusion—for quiet, quieter, and quietest performance. However,“noise reduction” does not mean “silence,” as sound levels will vary depending upon pellet choice. A lighter, faster and smaller caliber pellet, for instance, will produce a louder sound than a heavier, slower and higher caliber pellet. To further assist with your purchasing decision, please refer to the chart above. The Whisper Fusion technology incorporates a double integrated sound moderator making it the quietest Gamo air rifle. The pellet travels through two different chambers, compressing and preventing the noise expansion.

IGT MATCH1
Based off the groundbreaking IGT platform, the IGT MACH 1 replaces the standard spring power plant with an Inert Gas Cylinder, but the IGT MACH 1’s monster 33 millimeter cylinder delivers more velocity and terminal penetration. The pneumatic cylinder rockets pellets up to 1650 Feet Per Second (fps) in .177 caliber (with Alloy Ammunition), and promotes smooth and consistent cocking efforts with constant power delivered to any pellet you shoot. If you want: More Precision, Less Vibration and True Knock Down Power. Make sure your next Gamo has the IGT MACH 1 inside.

Custom Action Trigger
The revolutionary C.A.T. (Custom Action Trigger) enables Gamo air rifle owners to independently adjust the 1st and 2nd stages of their trigger to tailor the trigger pull and crispness to their personal preference. Simply loosen the 1st stage adjustment screw and the trigger travel increases. If a shorter travel length is desired just tighten the same screw to decrease the 1st Stage travel length. The 2nd Stage Adjustment is made justas easily —unscrew the adjustment setting to increase the 2nd Stage travel length or decrease it by screwing in the same adjustment point.

Recoil Reducing Rail
Gamo, pioneering the latest air gun technology, delivers the groundbreaking Triple R(Recoil Reducing Rail).The RRR was developed to subdue the taxing stresses placed on your scope from the intense recoil of air guns and high-powered rifles. The Recoil Reducing Rail uses patent pending two-piece aluminum construction separated by dual polymer struts to absorb the shockwaves generated by the recoil. Once the scope is mounted to the Recoil Reducing Rail, the recoil stresses to its internal components are reduced by almost 100%. Hunters demand: Scope Reliability, Reduced Vibration and Dead On Accuracy. The Triple R (Recoil Reducing Rail) — Preserve Your Scope’s Lifetime for the Next Time. Only from Gamo.
