Data sheet




  • 3 Cylinders Gearbox : Tokyo Marui has developed a brand new gearbox design especially for the AA-12, a pretty unique design as it features 3 individual cylinders that allows this AES (Automatic Electric Shotgun) to shoot 3 bbs simultaneously. The pressur on the trigger will make the shot happen and reload the next 3 bbs. The nozzle guide uses a new material called Kashima Coat (made by a Japanese company) that autolubricate itself. Everything has been thought so that the electric gearbox can shoot 3 bbs at a time, even in full auto mode, the smoothest possible.
  • Full & Semi Auto : The Tokyo Marui AA-12 can shoot full auto, just like the real one. Marui added a single shot mode (mode that is not on the real steel AA-12) in order to be allow the gun to be played in "semi only" games. The firing selector shows  “S” as for Safety and “F” as for Fire in full auto. An intermediate "click" in between allows to select the semi auto mode (no marking).
  • FET : In order to prevent electric damage the AA-12 is equipped witha FET that controls the electric current when shooting. It allows a better response from the trigger and helps the 3 BBs shooting system to cycle correctly.
  • Metal Inner Frame : The outside of the AA-12 is made out of plastic, just like the real AA-12, with 2 big shells. The outer parts like the outer barrel, the sights, the trigger guard are made out of metal and are fixed on an inner frame metal frame that strengthen the whole shotgun and includes the gearbox.s
  • 3 Hop Up Chambers : The AA-12 has 3 individual hop chambers (one for each 3 inner barrels) that can be adjusted through the setting wheels hidden behind the ejection port. This new system allows to widen the bbs' trajectory.
  • Adjustable Sights : Front and rear sights can be adjusted.
  • Box Type Magazine : A 93rds spare magazine is included. It is checked oin the outside for a better grip when reloading and also allows to hold the AA-12 with the weak hand on the magazine.

Extra !

J'adore cette réplique. L'utiliser en full auto en extérieur est vraiment sympa, bien plus au final qu'en intérieur en semi où elle sera vite moins efficace que des répliques plus classiques qui ont plus de facilité à être plus précise rapidement (c'est là que le manque de rail pour optique se fait sentir, son seul défaut).
Je ne suis pas un partisan des drums, ça peut vite devenir frustrant pour les joueurs en face, mais avec les chargeurs de base cela oblige à doser ses tirs et réfléchir pour être sûr de son coups.
Au final sa puissance inférieure à la moyenne est largement compensée par la précision de la bille centrale et la zone de couverture ajoutée par les billes latérales. J'ai déjà fait des touches sans problème à plus de 40m.

Vraiment très jouissif à utiliser !

Phenomenal !!!

There's no better word to describe it. It looks and feels great. It shoots perfectly. With the tri-hop system You are able to adjust the spread the way You want it to be. Even though it's a shotgun and Your max range is about 35m it still delivers during an outdoor game. I highly recommend it to anyone who's a fan of shotguns and doesn't like being outgunned by AEGs.
