There is absolutely no doubt that Tokyo Marui are without doubt one of the Premier, if not THE Premier manufacturers of airsoft. They've taken the robust internals from the AA-12 and with some more tweaking and playing, have produced the SGR-12.

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 from the AA-12 fits this perfectly too!.

Take a look at the Tokyo Marui publicity video HERE to see the BB devastation these types of shotgun give 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 SGR-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 SGR-12 is only designed to work with 0.20g BBs and heavier BBs can cause issues.

  • Based on the proven AA-12 Sledgehammer Design
  • 3 Cylinders, 3 Barrels, 3 Hop-Ups, scary fun!
  • Adjustable Hop-Up per barrel for increased range and accuracy
    • The two lower barrels apply side hop for greater spread

Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).

No airsoft AEG is warrantied for use with an 11.1v LiPo or higher voltage battery at UK velocities (373fps or lower) unless specifically recommended on the product itself. Use of higher voltage batteries can cause failures and will negate any warranty implied or otherwise.
