ProMag GSM01 10-Round Magazine 22 LR GSG 5 DuPont Zytel Polymer

The ProMag GSM01 magazine delivers reliable feeding for GSG 5 firearms with a 10-round capacity in .22 LR. This aftermarket magazine provides shooters with additional firepower and quick reloading capabilities for extended range sessions and training exercises.

What Makes This Different

Constructed from DuPont Zytel polymer, this magazine offers superior impact resistance compared to standard plastic alternatives. The reinforced polymer construction maintains dimensional stability across temperature extremes while reducing overall weight. Spring-loaded followers ensure consistent cartridge presentation, while the anti-tilt design prevents feeding malfunctions that plague cheaper alternatives.

Key Features

• 10-round capacity for .22 Long Rifle ammunition
• DuPont Zytel polymer construction for durability and chemical resistance
• Direct fit for GSG 5 rifles without modification
• Heat-treated steel spring maintains tension through thousands of cycles
• Removable floorplate allows easy disassembly for cleaning

Field testing demonstrates reliable cycling with standard velocity and high-velocity .22 LR loads. The magazine functions effectively in competitive shooting scenarios where rapid follow-up shots are critical. Temperature cycling from -20°F to 140°F shows no impact on feeding reliability or structural integrity. The polymer construction resists solvents and cleaning chemicals commonly used in firearm maintenance.
