People Airsoft were kind enough to share this information with us.  Although the official statement from the Police is somewhat silly, but  there is undeniable truth behind it. Not the part where these  "officials" claim various bogus claims of airsoft replica dangers, and  so on. Because, come on, what kind of a douchebag criminal do you have  to be to use airsoft replicas as your tool? The undeniable truth is,  Chinese government is coming after the manufacturers and distributors  who illegally manufacture these items, simply because the law requires  them to do so. Could this mean the end of cheap ACM replicas?  Time will tell...

There  are 110 thousands of airsoft guns carried by two containers. China  custom patrol intercepted those airsoft guns in Swatow city, Guangdong  Province and arrested three suspects during China National Holidays.  Total 113,000pcs of airsoft guns were seized, which is largest  gun-involved crime in the last decade. Based on official news from China  custom patrol, they caught those simulated guns when they were under  transportation to port after loaded at a local market in Swatow. Those  thousands of airsoft guns not only contain various real gun models but  simulate every detail, no matter on size, weight or structure from real  guns. Although simulated gun is differ from real one, it still shows  certain level of damage power and can be used as tool by criminals due  to its high similarity with real gun. According to China “Firearms  Control Act”, simulated guns are forbidden to manufacture and sale.  Presently, those airsoft guns are transferred and investigated by Swatow  Police department.
