VFC / UMAREX H&K MP7 GREEN GAS MAGAZINE – 40 ROUNDS

OEM VFC Magazine • 40-Round Capacity • Green Gas Powered • Official H&K Licensed Platform • VFC MP7 GBB Compatibility

VFC MP7 // UMAREX // H&K MP7 // 40RD GBB MAGAZINE // GREEN GAS // OEM VFC // NOT FOR KWA MP7

Keep your VFC MP7 GBB ready for the field with the VFC / Umarex H&K MP7 Green Gas Magazine – 40 Rounds, a full-size gas blowback magazine designed specifically for compatible VFC H&K MP7 Series Airsoft GBB SMGs.

Manufactured by VFC for Umarex under H&K licensing, this magazine provides a 40-round capacity and integrated gas reservoir for the realistic operation expected from the VFC MP7 gas blowback platform. Whether you need an additional magazine for your field loadout, a replacement for an existing magazine, or simply want enough magazines to avoid constantly reloading between games, the OEM design makes this the natural choice for compatible VFC MP7 owners.

Most importantly, this magazine is designed for the VFC MP7 system and is NOT compatible with KWA MP7 airsoft guns. Because several manufacturers produce MP7-style airsoft replicas using different internal systems, confirming your exact platform before purchasing is essential.


01 // DESIGNED FOR THE VFC H&K MP7 GBB

This magazine is purpose-built for compatible VFC H&K MP7 Series Gas Blowback Airsoft SMGs.

Using the correct magazine is particularly important with a GBB platform because the magazine does more than simply hold BBs—it also contains the gas supply required to operate the blowback system.

The OEM VFC design provides the appropriate interface for compatible VFC MP7 GBB platforms, making it an excellent choice as either a replacement or additional field magazine.


02 // 40-ROUND CAPACITY

Each magazine provides a listed capacity of:

40 ROUNDS

This gives the MP7 a realistic, lower-capacity GBB experience compared with high-capacity electric airsoft magazines.

For players who enjoy realistic reloads, tactical movement, and gas blowback operation, carrying several 40-round MP7 magazines creates a significantly different experience from running an AEG with hundreds of rounds available in each magazine.

Additional magazines also mean less downtime between engagements and fewer trips back to reload during longer games.


03 // GREEN GAS POWERED

The VFC MP7 magazine is designed around a green gas system.

The integrated reservoir supplies gas to cycle the MP7’s gas blowback mechanism while firing each BB.

Gas-powered platforms are affected by temperature, firing speed, magazine temperature, and gas pressure. For the most consistent performance, magazines should be maintained properly and allowed to return toward normal operating temperature after rapid firing.

Always use gas appropriate for your replica and environmental conditions.


04 // OEM VFC MANUFACTURING

This is not simply a generic aftermarket MP7 magazine.

The magazine is manufactured by VFC, the OEM behind the compatible Umarex H&K MP7 GBB platform.

For players already running a VFC MP7, choosing an OEM-specification magazine helps remove much of the uncertainty surrounding fitment and operating-system compatibility.

The magazine is marketed through Umarex under H&K licensing, matching the licensed VFC MP7 airsoft platform.


05 // BUILT FOR THE GBB EXPERIENCE

A large part of what makes the VFC MP7 appealing is its gas blowback operating system.

Unlike a conventional electric magazine, a GBB magazine plays a major role in the operation of the replica. It stores both ammunition and the pressurized gas required to cycle the system.

For that reason, quality magazines are an essential part of a dependable GBB loadout.

Having multiple properly maintained MP7 magazines can also improve your overall game-day experience by allowing magazines to rotate and recover between strings of fire.


06 // IMPORTANT: NOT COMPATIBLE WITH KWA MP7

MP7 airsoft magazines are not universally interchangeable.

This magazine is intended for:

✓ VFC H&K MP7 SERIES GBB

It is specifically listed as:

✕ NOT COMPATIBLE WITH KWA MP7 MODELS

A KWA MP7 and VFC MP7 may look similar externally, but they use different gas blowback systems and magazine specifications.

If you aren’t sure which MP7 you own, verify the manufacturer and operating system before ordering.

GBB CARE // PROTECT YOUR MAGAZINES

Gas magazines are precision pressure-containing components and should be treated accordingly.

Keep the magazine clean, inspect seals for signs of wear, use appropriate gas and maintenance products, and avoid dropping loaded magazines onto hard surfaces.

Do not expose magazines to excessive heat, tamper with pressure-containing components, or exceed the manufacturer’s intended operating conditions.

Proper magazine care can have a major impact on the reliability and consistency of your VFC MP7 GBB.


WARRANTY NOTICE // HPA MODIFICATION

Modification of Green Gas or CO2 magazines to accept aftermarket HPA fittings, valves, or other pressure-system components will void applicable included warranties.

Improper pressure, incompatible fittings, or misuse can damage the magazine and airsoft replica.

⚠ KWA MP7 // NOT COMPATIBLE

40-round MP7 magazines
provides additional ammunition and makes it easier to rotate magazines during longer games.

TEMPERATURE // GAS PERFORMANCE

Can cold weather affect performance?

Yes.
Gas blowback systems are temperature sensitive. Colder magazine temperatures can reduce gas pressure and may affect
cycling, consistency, and overall operation.

MAGAZINE TEMP // CONSISTENCY

Should I let the magazine warm up after rapid firing?

Allowing a gas magazine to return toward normal operating temperature after extended use can help
restore more consistent gas performance.

⚠ MODIFICATION // WARRANTY NOTICE

Can I convert this magazine to HPA?

Aftermarket modification of green gas magazines with
HPA fittings, valves, or other pressure-system components
should be considered a warranty-voiding modification and can create damage or reliability problems if the system isn’t configured appropriately.

aftermarket HPA fittings, valves, or similar pressure-system changes
