On amnesties; Neither IFs or RIFs are required for the sport. It could be hugely damaging to airsoft to run around with airsoft internals in externals akin to a supersoaker or nerf gun, the sport could survive... Though the implementation costs would destroy the sport.
Incidentally, any idea how this legislation could affect toy guns which are actually produced for children? What i mean to say is, if it was worst case, could toy guns, such as water guns and nerf get sucked up by these amnesties.
At first you might think, "why would they", but it would not take long for nerf clones to pop up with factory installed airsoft parts - if nerf guns were exempt (example), basically, it has to be all (unlicensed) guns or nothing?
Im sure we've all seen that vid of the guy shooting police in london with a nerf gun - cant be certain its not real ammo. We all know that all you need for a real gun is the ammunition, anyone with appropriate skills can create a firing device (a gun). Going after imitation firearms is a cheap shot that serves no useful purpose, imo, and as most others have said.
