[The Saint]

The idea that flashy colours and transparency can somehow lower the bar of age and suitability is silly. This is inherent contrary to the responsible practice of carefully screening minors for the maturity necessity to handle airsoft guns, because it's trying to de-escalate the airsoft guns so more minors can access airsoft guns without the same caution necessary with fully-opaque and non-flashy-coloured guns. The cart is now before the horse.

"Suitability" has nothing to do with the gun, or even age, and everything to do with the parents and their children. Suitable parents can take their children can go out on a range and shoot real firearms all day long without worry, they can hunt, they can play with full metal airsoft guns all day long. Parents and children responsible enough to have airsoft guns has no concern over the colour or there lack of, because they won't ever use the airsoft guns in an environment where it would be an issue.

Unsuitable parents and their children shouldn't even have a Nerf gun, much less airsoft guns.

Of course, the above assumes that this was done to protect the users from accidentally having their airsoft guns mistaken for the real thing. A real crazy idea would be that it's also being done to make airsoft guns seem more "paintball" and less scary to parents.
