A spare/replacement full metal Hi-capacity 330 round magazine for M4 type rifles. Fits most AEG M4 variants. To load the magazine open the hatch ontop of the magazine and pour BBs inside. Magazines can be fully wound in under 5 seconds using a drawstring to wind up in just 4-5 pulls. It then allows the entire magazine to be fired without re-winding due to the larger than normal spring. A heavy duty steel casing makes this magazine very durable and highly realistic, and it can be easily operated when wearing gloves. Fits all standard spec M4/M16 series AEGs.
