The Airsoft sport really took off in Japan in the early 80s at a time when it was illegal to own firearms in that country. Airsoft guns are 1:1 scale replicas of actual firearms that fire 6mm, round, plastic pellets commonly called as "BB's" which are propelled out of the guns by compressed air.
Zephyrpaintball.com which was founded in 2004, now carries cheap airsoft guns. The web site has Airsoft pistols and rifles arriving daily from Firepower, KWA and China Airsoft. One of the main objectives in founding Zephyrpaintball.com was to bring low prices, customer service and fast shipping to the paintball world.
