The Tokyo Marui SGR-12 shotgun is a futuristic and heavily modernized version of its predecessor, the AA-12 (Atchisson Assault Shotgun). This model is recognizable to all fans of the video game Resident Evil, where it appeared under the name Thor's Hammer.
Compared to the AA-12, the SGR-12 in airsoft version has several improvements:
TM SGR-12 is an airsoft replica AEG (electrically powered by batteries), with the heart of the replica being the so-called gearbox, which is a metal casing for additional internal parts that control the weapon's firing (performance). It is a set of metal gears that drive an AEG motor.
This electric shotgun is truly unique. It features 3 internal barrels, allowing it to shoot 3 BBs at once.
The gears push a long piston against a spring, and upon its release, the 3 piston heads compress air into the nozzles until they stop at the impact surface of the 3 cylinder heads. The 3 nozzles then send a BB into each of the 3 hop-up chambers and give them the necessary muzzle velocity with air.
In each hop-up chamber, there is an AEG rubber with a protrusion that spins the BB in the opposite direction, significantly increasing range and accuracy (hop-up is a patented invention from Tokyo Marui and has changed the world of airsoft since its introduction).
The shotgun also features full-auto firing mode, so opponents will be showered with a barrage of BBs that no one can escape. Safe motor switching is ensured by an installed FET unit.
*** Note: The FET unit prevents the use of a battery stronger than 7.4/8.4V ***
Thanks to adjustable Hop-up regulation, heavier ammunition can be used, achieving stable accuracy even at longer distances.
Due to Japanese restrictions and laws, Tokyo Marui weapons are designed with a power of up to 1 J (approx. 90 m/s) and their replicas are mostly made of plastic, but it is a patented reinforced Marui polymer that is strengthened for greater durability while being lightweight, making the weapon more maneuverable. Important parts of the weapon are made of metal (internal frame, barrel, and controls).
Quicker aiming, quicker hits.
Just purchase a suitable battery and magazines and you can look forward to a great game with a reliable weapon that will outshoot most other weapons even with a weaker base.
Because Tokyo Marui probably has the strictest quality control among airsoft manufacturers, you can be sure that your money is invested in the best!
