Important Notice

• The magazine is intended only for medium-power Green Gas, such as Nuprol 2.0.
• Using stronger gases (Red Gas / Black Gas) may damage both the magazine seals and the pistol. Such damage is caused by excessive stress on internal parts and seals and is not covered by warranty.

Frequently Asked Questions (FAQ)

How can I prevent gas leaks?

Regularly lubricate the seals with silicone oil and avoid storing the magazine completely empty. It is best to keep a small amount of gas inside during storage.

Can I use stronger gas for higher performance?

While Red Gas can theoretically be used in cold weather due to lower gas expansion, it is not recommended. Stronger gases increase wear and may damage both the magazine seals and internal pistol components.

Will it fit other Glock and G-Series pistols?

The magazine is primarily designed for UMAREX / VFC (Elite Force) pistols. Compatibility with other brands such as WE, Marui, or VORSK cannot be guaranteed and may result in feeding or fitment issues.
