Classic Army 500Rd Metal High-Cap Magazine for G3 AEGs, Black

If you're running a G3 AEG and tired of swapping mags every few minutes, a high-cap magazine changes the rhythm of your game. This Classic Army Metal 500 Round Hi-Cap holds enough BBs to push through a full skirmish without constant reloads, and the metal shell gives it a weight and feel that polymer mags don't match.

How it feeds. A winding wheel at the top advances the follower, keeping tension on the spring so BBs feed reliably. You'll hear the rattle as you move—that's normal for hi-cap design. The wheel is easy to crank between exchanges or during lulls in the action. It's not silent, and it's not meant to be; it's for players who prioritize ammo capacity over realism.

Metal construction. The stamped metal outer shell is heavier than polymer alternatives, which adds heft to your loadout but also durability. The black finish matches Classic Army G3 AEGs cleanly. Metal also means this mag will dent before it cracks, and it won't warp in heat the way some plastics can.

Capacity in context. 500 rounds sounds like a lot, and for a single mag it is. But a G3 running full-auto will burn through that in a couple minutes of sustained fire. If you're playing support or just want fewer reloads on casual game days, this works. For serious milsim where weight matters, you'll want mid-caps instead.

Platform fit. This is made specifically for Classic Army G3 Series AEGs. It won't fit M4s or AKs. The G3 mag ecosystem is narrower than the universal M4 pattern, so when you find a compatible mag that works well, it's worth keeping.

What's in the box. Just the magazine. No BBs, no speed loader. You'll need to fill it yourself with a speed loader or by hand.
