*Manual Safety: The manual safety is the lever that is in front of the trigger, if you pull it forward, the safety is off, if you pull it backwards (towards the trigger), the safety is on. Please make sure you do not turn the safety off until you are ready to shoot.
Automatic Cocking Safety System: The automatic safety cocking system is a different safety feature than the Manual Safety; it does not allow you to pull the trigger while cocking the air rifle. When you break the barrel this safety system is engaged and when you put the barrel back into position this safety system is disengaged.
Please read the manual before using.

The Gamo Hunter Extreme .25 rifle features our most powerful 33 mm cylinder and IGT Mach1 gas piston, allowing it to deliver next-level power with 1,000 fps in .25 caliber. It features a high quality beechwood stock with checkering on the grip and forearm, the CAT (Custom Action Trigger), the RRR (Recoil Reducing Rail), a Gamo 3-9×40 scope and automotive grade glass filled nylon thumbhole stock.

This Kit includes:

  • Gamo Hunter Extreme .25 rifle
  • 2 tins of Pro Magnum .25 pellets (350 pellets total)
  • 50 Gamo paper targets
  • Protective Plastic Cover


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 1000 Feet Per Second (fps) in .25 caliber (with Alloy Ammo), 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.

The Hunter Extreme Ultimate Kit .25 features a high-grade made in Spain beechwood stock, bringing the traditional air rifle experience to this category. The stock has laser engraved checkerings on the grip and forearm. It also has the Gamo logo engraved underneath the grip.

CAT (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 just as easily —unscrew the adjustment setting to increase the 2nd Stage travel length or decrease it by screwing in the same adjustment point.

Gamo, pioneering the latest air gun technology, delivers the ground breaking 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.
