"Airsoft" originated in Japan during the 1970-ies. An individual in Japan cannot own a firearm, and we as humans are fascinated with guns. Contrary to liberal believes, this fascination is not limited just to the United Status. The first airsoft guns available were spring-powered replicas of firearms that fired 6mm plastic BBs.
Airsoft guns (by the way there is nothing soft about those plastic BBs! so don't ask us why it's called airsoft) quickly became popular all over Asia and took roots in the United states a few decades later.
Today, airsoft is an amazing sport, that's been around for more than 2 decades and continues to provide an immense amount of entertainment to those who venture out into the field or choose to train their tactical skills in a CQB environment.
Enter if you dare.
