Not exactly big news, but an interesting development:
4. Based on the latest research, it is now established that the muzzle velocity at which a .20g 6mm plastic airsoft projectile is capable of causing serious bodily injury is 111.6 m/s (366 fps).
5. Airsoft guns, firing a .20g 6mm plastic pellet, with a muzzle velocity above 111.6 m/s (366 fps), will be classified as firearms. Please refer to D19-13-2 for the import requirements of low muzzle velocity firearms, including low muzzle velocity “uncontrolled” firearms.
Came into effect yesterday, I have an
article up about it here if anyone's particularly interested.
