A&K is a Chinese manufacturer of AEGs. They are most notable for their Magpul Masada, M249, and M60. A&Ks are available from about $150 to $400 at most airsoft retailers. A&K is considered to be an entry level airsoft gun manufacturer. However, they have some features that even manufactures like Tokyo Marui do not have, such as one-piece outer barrels and delta rings. One of the most affordable entry level AEG on the market.
A&K was closed during the Chinese crackdown on airsoft manufacturers (2009). Their factory boss was also jailed, as making toy guns is a serious offense in China. However, A&K, as of May 2010, is back to manufacturing.
