There are several reasons why you would want to dye your PMAGs. Maybe you use different magazines for different calibers, and having separate colors will help tell them apart. Perhaps you participate in competitions, and you don’t want other people picking up your magazines, mistaking them as theirs. Or maybe you just wanted something different and thought they look cool. Who am I to judge?
Personally, I wanted a way to differentiate my AR-9 magazines with EndoMags insert apart from my 5.56mm ones. The process was straightforward to do was decently impressed with the outcome. Even though I didn’t achieve the color, I was shooting for, but we will get into that a little later.
