APS AK-74 600 round Hicap AEG Magazine High capacity magazines are the favorite magazine for airsoft players. High capacity (Hicap) magazines usually hold 150 rounds or more. These magazines work using a tensioned mainspring (similar to a mechanically wound timepiece) or an electrically driven feeding gear. The advantage of these magazines is the simple fact that they are able to hold a great many BBs. Most beginner or intermediate AEGs come with a high capacity magazine. These are a favorite for almost all airsoft players. The distinguishing feature of Hicap magazines is the teeth of the star wheel visible on the bottom of the mag. Simply wind the wheel until a more audible clicking noise is heard and it is more difficult to spin the wheel. Speedloaders are not needed with this type of magazine, just a big bag of BBs and funnel to direct their flow. *Note: This magazine is more susceptible to damage from poor quality BBs and FOD (Foreign Objects or Debris). Be sure to use BBs of good quality in this magazine.
