Unique adult air weapons designed today for the shooters of tomorrow


The Gunpower Storm is an adult air weapon designed today for the shooters of tomorrow.

Walther Match Grade Barrel

The Storm rifle again has all the features of the Stealth but with an 18” (45cm) Lothar Walther match grade barrel which can give either more shots per fill at low velocity or an improved top velocity achieving up to 950 feet per second (330m/s) depending on pellet weight, calibre and power setting.

Because the barrel extends beyond the frame of the rifle a different moderator is used (where permitted), designed from light-weight Carbon Fibre and fully baffled for maximum effect.

Ergonomic Design

The firing system is ergonomically designed with an automatic safety and easily accessible safety release, two stage trigger, an over-sized cocking knob, a large pellet loading port and a burst disc to prevent over filling on the tank.
