Airsoft has a thousand variations, not only "MilSim Vs Pachangueo". There are also more "futuristic" versions that seem directly taken from a science fiction movie. It is cool because he's not letting scripts SEAL VS Taliban, to test an Alien VS Predator.
Here are some Steampunk models created by Johnson Arms rom Nerfs, which are not airsoft replicas but can help us to imagine how could we leave our airsenal. What do you think?
