To call filling of the roll-marks "vandalism" is, at best, silly! People fill the lettering on their guns for any of several reasons, all legitimate!
...........There are also paint sticks available in many colors. The most frequently seen are white and red, although yellow, orange and other colors are available.
Cleaning Tip ... Oral-B toothbrush handles don't melt .Acetone while loosening and then allowing you to scrub the colored mtr'l out of the lettering,,using a plain regular toothbrush may bring you added problems.
Acetone disolves (melts) many plastics,,common toothbrushes being one of them.
Not all of them are effected in that way, but many are. Maybe it depends on where in China & likey from what exact plastic or nylon the brush gets mfg'rd of.
So scrubbing the surface with the acetone soaked toothbrush may start to lay down onto the metal a heavy coating of the plastic that the brush is made of.
That right over and even mixed with the colored product that is softened as well.
It can all be cleaned up of course with more acetone on just a clean cloth minus the further use of that particular toothbrush or any other that has the tendency to disolve in acetone.
But you might want to trial run any particular brush with some acetone first on a plain metal surface like a tin can top just to see if the plastic disolves onto it before attacking the firearms parts.
The M16 cleaning brushes commonly called and looking like a toothbrush are chemicaly resistant to acetone FWIW.
