Gamo G-Magnum 1250 Whisper IGT Mach 1 5.5 mm Air Rifle Set FP

Gamo G-Magnum 1250 Whisper IGT Mach1 Air Rifle, 5.5 mm Full Power

The Gamo G-Magnum 1250 Whisper IGT Mach1 air rifle in 5.5 mm (.22) Full Power caliber comes as a set with a Gamo 3-9x40 scope included. This is a full-power air rifle with a muzzle velocity of up to 380 m/s and energy of up to 45 J —however, these parameters always depend on the type of ammunition used and represent the maximum achievable values.

The Spanish brand Gamo is among the top-quality manufacturers of airguns, and their models are also affordable. For a reasonable price, you’ll get a functional, powerful, and aesthetically pleasing airgun. The high-quality craftsmanship of the mechanical parts is particularly evident when handling the rifle—everything operates smoothly, without any grinding or resistance.

The air rifle utilizes IGT Mach1 technology, which replaces the classic wire spring with a gas spring in an enlarged cylinder (from the standard 29 cm to 33 cm). This applies constant pressure to the piston, allowing it to deliver the air needed for the shot at a more optimal timing, which positively affects the shooting performance.

The steel rifled barrel in 5.5 mm / .22 caliber is fitted with a functional sound compensator and has a total length of 538 mm. This combination ensures accurate and quiet shooting.

The air rifle’s overall length is 1,255 mm and it weighs 3,200 g —these specifications make it a weapon better suited for adult shooters seeking maximum performance.

Aiming is facilitated by standard mechanical sights featuring Tru-Glo elements—light-conducting fibers. The fully adjustable rear sight has green fibers, while the fixed front sight has red ones. If the mechanical sights are not sufficient for you, the air rifle can easily be fitted with a scope or red dot sight—the barrel is equipped with a Gamo RRR rail, which provides a flat profile for easier mounting of an optical sight.

The G-Magnum series is equipped with a premium CAT (Custom Action Trigger) trigger mechanism, which allows you to adjust both the trigger travel ( the “first stage”) and the travel and resistance of the trigger action itself ( the “second stage”).

The safety mechanism to prevent accidental discharge is located in front of the trigger in the form of a small lever operated by sliding it forward and backward. When the lever is in the position closer to the trigger, the air rifle is locked; to unlock it, simply slide the lever away from the trigger.

To reduce weight, the entire air rifle system is housed in a polymer stock with a cutout, which is highly durable and long-lasting. The stock’s ergonomics and the shape of the cheek rest allow for comfortable shooting by both right- and left-handed shooters. At the end of the stock, you’ll find an SWA rubber buttplate with adjustable recoil damping.
