Warning

• The magazine is designed only for medium-pressure Green Gas, such as Nuprol 2.0.
• Using stronger gases (Red Gas / Black Gas) may damage the magazine seals and the pistol itself. Such damage is not covered by warranty as it results from excessive stress on internal components and seals.

Frequently Asked Questions (FAQ)

How can I prevent gas leaks?

Regularly lubricate the seals with silicone oil and avoid storing the magazine completely empty for long periods. Ideally, keep a small amount of gas inside during storage.

Can I use a stronger gas for higher performance?

In cold weather, Red Gas can theoretically be used because gas expansion is reduced at lower temperatures. However, we do not recommend it, as stronger gases increase wear and may damage both the magazine seals and the pistol’s internal moving parts.

Will it fit other Glock and G-Series pistols?

The magazine is primarily designed for UMAREX / VFC (Elite Force) pistols. Compatibility with other manufacturers such as WE, Tokyo Marui, or VORSK cannot be guaranteed and may vary.
