VFC M4 Green Gas Magazine V3 30 Round Airsoft Magazine, Grey

Gas blowback magazines are the most expensive recurring cost on a GBB loadout. They hold BBs and fuel, they're platform-specific, and you need spares. This one covers the two most common AR-pattern GBB platforms: VFC and Umarex.

Compatibility. This 30-round green gas magazine fits VFC and Umarex AR-pattern GBB rifles: AR15, M4, HK416, VR16, SR16, MK12, MK18, CAR XM177, T65, T91, and FN FNC. It works in standard AR-pattern magwells. Green gas magazines are platform-specific and more expensive to replace than spring-fed AEG mags, so that broad compatibility list matters. This is a gas magazine, not an AEG mag — it won't work in an electric rifle.

Build. Metal and polymer construction, 190mm long, gray finish. V3-design magazine.

Before you buy. Green gas is not included. Plan on carrying three or four mags if you run full-auto, because a GBB mag empties faster than most players expect. Green gas performance drops in cold weather — if you play late fall or winter, CO2 magazines are the better choice.
