In general most airsoft gun manufacturers including Tokyo Marui, Classic Army, G&G, Cyma, Jing Gong (JG), UTG, etc; follow this same version/model/mechbox standard. Please note that variations exist among manufacturers ie: A Classic Army version two gearbox will not be the same as a tokyo marui type 2.

The list of air soft guns and mechbox, gearbox models is changing all the time due to the exploding popularity of airsoft in the USA. Many of the replica models listed above are now manufactured by more than one company. Airsoft soft gun manufacturering companies are listed in China, Japan, Taiwan, France, Germany, USA and more.

The list above is meant only as general guide to airsoft gun repair and is not all inclusive. Many changes and constant evolutions in the airsoft industry are taking place daily.  Basically we are just pointing out that a classic army v2 gearbox will be the same as a G&G or a Tokyo Marui and if you have worked on one style IE: V2, V3, then you can most likely succeed with repairing other manufacturers V2. This is not always the case as shown with the V7 mechbox repair pictures of the Tokyo marui m14 and the G&G m14. Although the air soft gun styles are the same the mechbox build is quite different.
