WHAT IS IT?
There's a detailed write-up about it here. Basically, to call out the specifics, the bill would require all Airsoft gun exterior be white, bright red, bright orange, bright yellow, bright green, bright blue, bright pink, or bright purple.
HOW DOES THIS EFFECT OREGON?
A gear majority of Airsoft guns imported into the United States come through California. Some of the largest Airsoft retailers in the country reside there. This would cripple the Airsoft economy in the United States and cause several manufacturers to lose money. It may be harder and harder to find realistic Airsoft guns, or their prices could be increased. The whole country could be effected by it. Not to mention, other states could try to pass similar bills.
Some of these California retailers have been supporters and sponsors of Airsoft Pacific for a long time, and have provided $1000's worth of gear donations for the events you guys attend.
