Magazines for your AEG, GBB, CO2, AEP or Sniper rifles and pistols.
Airsoft Magazines come in a lot of varieties such as Hicap, Midcap, Lowcap, Realcap and Flashmags but also GBB, CO2, or for example a Drummag.
By default, most replicas come with a Hicap magazine, these can be recognized by the winding wheel at the bottom. In Midcap, Lowcap and Realcap magazines you need a speedloader to be able to fill these with bb's. A Flashmag is an example of a Hicap, but instead of a wheel you have a string to pull on to load the bb's.
