There is absolutely no doubt that the Tokyo Marui AA-12 automatic electric shotgun has been the most talked about and eagerly awaited airsoft product over the last 18 months or so. The confirmed release date in Japan is the 15th January 2015 !!

So what is all the fuss about? It's just another AEG right? NO, absolutely not :)

For starters it's a tri-shot shotgun with a full spec electric gearbox with a select fire option of semi-auto and full auto. However, that's not really the cool part.....

Similar to the spring cocking shotguns that Tokyo Marui also pioneered some 15 years ago, they have not just attached an electric gearbox. What REALLY makes this auto-blunderbuss beyond awesome is the individual dial-up function of each separate hop-up unit associated with each of the three barrels. Picture this: with hop-up off, the rifle will fire three shots in a very close grouping. The more hop up you dial in, the wider the grouping. However, as you can adjust each barrel separately, you can have one barrel shooting straight ahead, the second barrel aiming off to the left and the third barrel placing BB's off to the right. It's entirely up to you how far you want the grouping to spread in each of the three directions!

Multiply that firepower with a full-auto firing mode and you can imagine how difficult it's going to be to miss your opponent :) After all, that's what the real version was designed for in the first place.

Comes supplied with one 300rd capacity 'Sledge Hammer' long magazine. This is a 93-shot mag though, as it fires 3rd bursts with every shot: 3x100=300 and somehow the mag 'loses' 7 shots somewhere........interesting :)

The 3000rd (1000-shot) drum mag gives you awesome sustained firepower.

Take a look at the Tokyo Marui publicity video HERE to see the BB devastation this shotgun gives you.

You might want to skip to 3m:27s for the actual grouping shots....



  • Due to the nature of this rifle, Tokyo Marui have built-in a voltage protection circuit. If you try to use these with anything more than an 8.4v mini battery or a 7.4v LiPo, the shotgun will not fire. It also trips an electronic 'flag' on the circuit board which invalidates your warranty and cannot be reset.
  • DO NOT UNDER ANY CIRCUMSTANCES dry fire your AA-12. This will shatter the custom pistons and is not covered under warranty.

  • If the battery voltage drops too far, the shotgun will stop firing and a red LED will start blinking in the stock.
  • The AA-12 is only designed to work with 0.20g BBs and heavier BBs can cause issues.
