Full description


Tokyo Marui are back, and once again showing off their legendary Marui design magic with this unbeatable Airsoft AEG replica of the AA-12 fully automatic combat shotgun. The AA-12, also known as the Auto Assault Shotgun, has rocketed to fame recently thanks to it’s appearance in a variety of popular video games and Hollywood movies, and thanks to the Airsoft engineering wizards at Tokyo Marui you can own it as a fully functional Airsoft replica.

How do you recreate such an infamous and iconic weapon on their Airsoft field? Tokyo Marui’s answer was “barrels – three of them”! That’s right, this AEG shotgun features three individual inner barrels, all linked up to fire simultaneously with each trigger pull. Marui don’t do things by halves and fitted each barrel with its own adjustable Hop-up, allowing you to get the perfect grouping and range from this triple-linked beast. The three Hop-up units are accessible behind the mock ejection port.

The AA-12 is supplied with a 90 round midcap magazine, based on the standard AA-12 box/stick magazine. You’ll get 30 trigger pulls out of this before you need to reload, putting you at a significant advantage over other Airsoft shotgun users.

Externally you can’t mistake this for anything other than the AA-12, as we’ve come to expect from Marui they’ve accurately recreated the real thing down to the smallest detail. Constructed from durable polymers with a rigid alloy inner frame, the pistol grip is knurled to provide a comfortable grip, whilst the pistol grip, handguard and magazine feature textured anti-slip panels, to ensure users have firm control over their Airsoft weapon. Ample battery storage space is provided in the stock of the Airsoft AA-12, allowing users to fit a wide range of large batteries.

As per the real thing the TM AA-12 features functional built-in iron sights, with the rear sight bweing adjustable for windage. Front and rear sling loops are also provided, allowing users to comfortably carry the AA-12 for prolonged periods.

Packed to the gills with all of Marui’s hallmark high standards of designing, manufacture and quality, this Airsoft AEG replica of the AA-12 is a must have for those Airsofters looking for an intimidating weapon for the skirmish field.
