I also understand that the industry is heavily regulated in the United Kingdom, too.
I find it interesting that we use an orange tip to distinguish an airsoft gun from a real gun. In the United Kingdom, to better differentiate between the two types of guns, they sell two tone airsoft guns, whereby 51% of the surface is covered in blue, green or orange. This makes the gun much less realistic and clearly shows that it is not a real gun.
If the government were to impose regulations that would require distributors to sell guns that have been painted in different colours, would you be okay with that?
