High capacity for sustained play

The Evolution 300rd Metal Hi-Cap Magazine holds up to 300 rounds, giving you the sustained fire and reduced reloading that fast objective games and support roles demand. Load it up and you can focus on the game rather than constantly topping up your ammunition.

Simple, reliable hi-cap feeding

A winding wheel on the base re-tensions the internal spring to keep BBs feeding up into your AEG. Give it a wind roughly every 50 shots and the magazine keeps delivering, using the proven hi-cap system that airsoft players have trusted for years.

Fast top-hatch loading

Filling the magazine could not be easier. Flip the hatch at the top, pour in your 6mm BBs and close it up. There is no need for a speed loader, so you can get back into the action quickly between games.

Built tough for M4 platforms

The metal body resists dents and wear from repeated magazine changes and hard use, while the STANAG profile fits Evolution M4, Ghost, Recon and 416 series AEGs and other compatible rifles. Keep it fed with quality ammunition from our BBs, gas and batteries range, and browse more airsoft accessories to round out your loadout.

Frequently asked questions

How many BBs does it hold?

It holds up to 300 rounds, making it a high-capacity option for players who want to stay in the fight longer between reloads.

How do I keep it feeding?

Wind the wheel on the base of the magazine to re-tension the internal spring, roughly every 50 shots, and BBs will keep feeding up into your AEG.

How do I load the BBs?

Flip the top hatch on the magazine and pour your 6mm BBs straight in, then close it up. No speed loader is required for this hi-cap.

Which guns does it fit?

The STANAG profile fits Evolution M4, Ghost, Recon and 416 series AEGs, along with many other M4 and M16 pattern airsoft rifles.

Why pick a metal body?

The metal casing adds durability and a more authentic feel, standing up to repeated reloads and rough handling better than a polymer shell.
