ASG STEYR M9-A1 GNB CO₂ Pistol – 4.5 mm Steel BBs (.177), Black
The ASG STEYR M9-A1 GNB CO₂ is a powerful and realistic 4.5 mm (.177) steel BB air pistol, designed strictly for target shooting and training. Manufactured by ASG under license from Steyr, this replica captures the modern ergonomics and distinctive styling of the original Steyr M9-A1.
Featuring a fixed-slide (Non-Blowback / GNB) design, the pistol focuses all CO₂ energy into performance, achieving muzzle velocities exceeding 120 m/s and an impressive 2.7 J of energy. This makes it an excellent choice for precision plinking and controlled range use.
High-Performance CO₂ System
Powered by a standard 12 g CO₂ cartridge, the STEYR M9-A1 delivers consistent power and a high shot count per cartridge. The integrated Easyload system built into the grip allows quick and tool-free CO₂ replacement, minimizing downtime.
