ProMag GSMA1 GSG-5 Magazine 22LR 22-Round Black Polymer

The ProMag GSMA1 delivers reliable feeding and extended capacity for GSG-5 rimfire rifles. This 22-round magazine addresses the limited capacity of factory options while maintaining the feeding reliability essential for training and recreational shooting.

What Makes This Different

Constructed from DuPont Zytel polymer, this magazine offers superior impact resistance compared to standard polymer alternatives. The reinforced feed lips maintain consistent geometry under repeated loading cycles, while the heat-treated spring provides reliable feeding across the full 22-round capacity. Factory GSG-5 magazines typically hold 10 rounds, making this nearly triple the standard capacity.

Key Features

• 22-round capacity extends shooting sessions without frequent reloading
• DuPont Zytel polymer construction resists cracking and environmental stress
• Heat-treated magazine spring maintains consistent tension
• Reinforced feed lips prevent deformation during loading
• Drop-free design enables rapid magazine changes
• Textured grip surfaces improve handling in wet conditions
• Compatible with all GSG-5 rifle variants and configurations

Field performance shows consistent feeding with standard velocity and high-velocity 22LR ammunition. The extended capacity proves valuable for competitive shooting disciplines, training exercises, and extended range sessions. The polymer construction withstands temperature extremes from -20°F to 140°F without compromising function or dimensional stability.
