Ban firearms in Japan

 

After the end of World War II, Japan with its new constitution regulates the possession of firearms to civilians following the armistice imposed by Américains.La regulations are so strict that it is virtually impossible having a gun at home, much less a weapon of war in a collection of purposes, including the neutralized weapons, which are incidentally the most expensive in the world, neutralization often costing 5 times the weapon's price itself. However, there is a strong demand from collectors to own guns even if they plastic for lack of means or lack of weapons neutralized. In the late 1960s thanks to appearMaruzen firm that has pioneered in the field, cast replica weapons totally inert plastic, especially for the collection. Sometimes these replicas were made of resin and metal with functional part as true. But to comply with the legislation, these replica weapons were designed and modified so that it is impossible to fire live ammunition.

 

 

The first functional replicas

 

By the mid-1970s and in compliance with Japanese laws imposing the impossibility of transforming an object weapon fire, technicians and engineers begin processing or manufacturing, these inert replica weapons replicas of weapons that can fire projectiles, non-hazardous, all using compressed air. The choicethen immediately drawn to the balls 6 mm. Because Japanese law the "launchers" can not grow more than 2 joules gun exit. Given the popularity of some of many of these "replicas ballistic weapons," which have the same functionality as the real weapons, opponents play 2 teams are emerging as the Survival Game or Wargame. Replicas then take the name airsoft guns. Fort known engineers today are from this era, as Tanio Kobayashi.

 

 

The problems of gas replicas

 

The problem with antique pitchers was congested air cylinders used in order to draw the replicas. Sometimes internal cylinders are made in replicas or shippers,improving the realism. But the use of high pressure air application very seriously and then reserves these replicas to a small group of enthusiasts. In the late 1980s all airsoft guns operate at low pressure gas (10 bar) or compressed air. Cylinders (in 2008) did not measure more than 5 cm and lodge in the handle guns and shoot 250 shots without the recoil of the breech and 80 blows with the recoil of the breech for greater realism. All this however depends on the weight of the cylinder head (plus it is heavy, it will have more energy and therefore gas to cook) and thus varying the number of possible shots with a single charge of gas.

 

The arrival of electric replicas

 

In the 1980s, Tokyo Marui, a Japanese company then specialized in low-end model, launched into the airsoft industry by producing replica weapons using the technology of remote-controlled electric cars. Compressed air is then supplied by a piston pushed by a spring, itself reinforced by a gear system driven by an electric motor in a "gearbox". The energy necessary for propulsion of the beads is then drawn from an electric accumulator. The ease of use and maintenance of this type of replica is such that it is the main trigger of the success of the activity. Tokyo Marui started with the production of the French FAMAS (replica appreciated by part of the population of Japanese airsoft with its futuristic look) and is a great success. Then follow quickly the range of M16A1 and M16 VN (Vietnam), then the CAR-15 and XM 177E2 and the MP5 and then expand its range of products to dozens of aftershocks.

 

In 1993, Tokyo Marui invented and patented the Hop-up. This system allows to increase the range of the balls without increasing the power output of the latter. The systemth is based on the Magnus effect, discovered by the German physicist Heinrich Gustav Magnus (1802-1870), which in particular to explain the bullet effects in sport. The system allows, thanks to a piece of rubber to rub the ball at the moment of propulsion, and thus rotate on itself and such a lift tennis to do "fly".
