Hi there, I am relatively new to airsoft and I am looking to buy a gun off prefired however it is black or RIF. Am I allowed to buy it and paint it myself? So long as it is the majority a bright colour, also it is a bit ambitious but to recreate a gun skin from a video game such as csgo in which it would have all over details and design but may not have a sharp bright colour, is that allowed if it doesn't look like a real gun?
