@Dayton Thanks for the correction. Looks like in the revision they changed it to "...a projectile no BIGGER than 16mm in diameter," which would indeed include airsoft guns.
Another day, another baseless, stupid, and freedom-infringing law proposed in COMMIEfornia. Personally, I don't think this will stand. They've tried this before... What was the last one? SB 798, right? Didn't pass, neither will this. It would effectively cripple the industry in the U.S., which the manufactures, distributors, retailers, and community won't take likely nor let happen without one hell of a fight.
One thing that is a bit confusing to me about the law though, is that it cites the 'regulation' of imitation firearms. What exactly does that mean? More taxes on them? Higher age limits to purchase them? Local government oversight over their sale/distribution? Hell, REGISTERING them? Can anyone shed some light on how exactly they plan to 'regulate' airsoft replicas with this new law if it were to pass?
Shoot, I wouldn't be surprised if this was some sort of legislation Commiefornia is testing on replica guns, in order to eventually take it one step further into REAL firearms... But that's a discussion for another topic.
