Hi, I bought myself a two tone aeg and I want to spray paint it, or at least cover the orange parts in camo tape; the site I go to is heavily forested and the orange part of the gun always gives my location away. Now, I am 18 years of age but I don't own a ukara membership so how would I be able to do this legally? I've looked around this topic and everyone just gives conflicting answers :/ Many thanks!
