Benefits of the IGT MACH 1 over a metal mainspring:

  • Large cylinder delivers more velocity and terminal penetration
  • Smoother cocking and shooting
  • Increased precision and speed
  • Less vibration
  • No spring fatigue, even if you leave it cocked for hours
  • Functions perfectly in cold weather
  • Lasts longer than a metal spring

The Gamo Magnum air rifle shoots pellets at a stunning 1650 feet per second (with .177 caliber PBA Platinum ammo). If you're looking for speed, this is the air rifle for you!

Endowed with features that make it comfortable to shoot and suited for hunting, this magnum-powered air rifle is lightning fast, and its equipped with a 3-9x40 scope that has an adjustable objective for even more versatility in the field.

The IGT Mach 1 powerplant delivers higher downrange energy and the ultimate in impact and penetration making this gun ideal for small game such as rabbits, squirrels, raccoons, and crows. The IGT Mach 1 delivers faster velocity, more power and even better precision by using a gas cylinder versus a conventional spring. And the IGT Mach 1 offers smoother cocking and shooting, no spring torque, no spring fatigue, no issues shooting in cold weather, and a much longer life than a spring powered gun. The IGT Mach 1 allows you to cock the gun and wait before taking your next shot without worrying about any weakening of the metal spring. You'll also notice a lot less twang and vibration.

The synthetic thumbhole stock has a comfortable, ambidextrous cheekpiece, making it ideal for right- or left-handed shooters, and for added comfort, the Gamo Magnum has rubber inserts on the grip, forearm and cheekpiece. The buttpad incorporates the Shock Wave Absorber (SWA) for more recoil reduction. And while the Mach 1 gas piston seriously reduces vibration, the SWA recoil pad stops you from feeling most of the recoil from the remaining movement of the gun.

The air rifle features the smooth and predictable Custom Action Trigger (CAT) that allows you to tailor the trigger to your own personal preference. And, only Gamo offers the Recoil Reducing Rail (RRR). Designed to subdue the stress on your scope, the RRR absorbs shockwaves and reduces the stress on the internal components of your scope by almost 100%.

Things I liked: Power, accuracy, and solid value. Scope is good quality as well.

Things I would have changed: Loud as a M$ther F$cker... Id add a better suppressor. Loud as a .22 lr.

What others should know: Owned it for 2 days.. Took me more shots than I wanted to get it sighted in. Now I cant miss if I tried. Only shot out to 40 yds, but clipping water bottle caps at that distance. Going to sure up my confidence for deer season big time.

  • John from India asked:

    Where can we get the original Gas Ram if we need to replace it? And how many shorts will a brand new gas spring. Can shoot with good power?

    • John from India asked:

      How loud is this gun? Is the same velocity in silent. Version?

      • Mark from USA:

        The magnum is about half the sound of a 22 LR. The velocities are identical.

    • Chris from Canada asked:

      I have the Gamo magnum 177 and I was wondering if I can switch it over to a 22 by just changing the barrel
