WellFire 31 Round Green Gas Magazine for WellFire Mac 11 GBB SMG, Black

The WellFire Mac 11 is a compact gas blowback SMG, and this magazine is what feeds it. Thirty-one rounds may not sound like much compared to the hundreds you get from an AEG hi-cap, but that's the reality of GBB magazines: they trade capacity for the recoil and bolt cycling that make gas blowback worth running. You'll be swapping mags more often, and that's part of the experience.

Full metal construction. The body and follower are metal, not polymer. That means it can take the bumps of a full game without cracking, but it also adds weight to your loadout. If you're running multiple mags in a chest rig or mag pouch, you'll feel the difference compared to plastic alternatives.

Platform specific. This magazine is made for the WellFire Mac 11 GBB SMG. It will not fit other Mac 11 clones or any other platform. If you need spares, you need to find this exact model. There's no universal GBB mag ecosystem like there is for M4 AEGs.

Maintenance matters. Gas magazines need regular attention. Silicone oil on the valve seal keeps them from leaking, and letting them sit fully pressurised for weeks will shorten the life of the internal seals. Drain them if you're not using them for a while, and keep a small oil bottle in your gear bag.

Before you buy. Battery and charger are not included — this is a gas magazine, so you need green gas or propane with silicone oil. You'll also want at least two or three spares if you plan on playing full games. One mag at 31 rounds empties in seconds on full-auto.
