Technically speaking all airsoft guns are "clones" so it surely is not the end of all airsoft gun imports, as many do not come from China. Japan and Taiwan, Germany and France all have IM Clone style airsoft guns for sale at prices that range from $50.00 to $5000.00 dollars per clone.
As for all the rumors of AGM and Cyma closed for good, First, I have heard of various issues with exporting the full metal airsoft guns AGM was producing. Perhaps these full metal clones were just built to good, as every one I have handled, used and customized has been rock solid and uses standard replacement parts.
Finally As for Cyma I think they will be around for awhile as well. These guys have been making airsoft clones since the beginning. They have cloned both pistols and assault weapons with the AK 47 series being widely known. You can also find Cyma parts and gearboxes in Aftermath and other re brands and second market airsoft guns. I think before Cyma stayed closed they would just move to a new Country and set up airsoft clone shop.
Bottom line, airsoft games around the USA are growing in size and demographics. The airsoft game story lines are changing and games with Zombie, Milsim and WWII themes have become popular, feeding the need for all styles of airsoft historic reproductions, replica's and clone's. Along with game growth goes airsoft gun and part sales which have quickly become a billion dollar a year or more market. Many U.S. Military and Police groups have adopted airsoft guns for training further driving the need for duty weapon type clones.
Economies are fueled by demand and right now airsoft clones in the USA are in high demand. We may see a price increase for the short term but I highly doubt the Chinese im clone versions will be gone from the market for long. The names stamped into the airsoft gun bodies may change, but I bet a deeper look at the airsoft gun's internal DNA will reveal the true identity of your airsoft clone's daddy.
