OK, stack of mags, gun, at the range.....thinking of marking a small "+" on the ones that work out of X rifle, and a small "-" on the ones that don't. Anyone do something similar? What kind of marker can be used that will later rub off fairly easily?

Use paint, I don't have amy experience, I just think that it would work pretty well. Some white krylon with "+" and "-"stenclis.

I use a White Out pen and number mags. If a mag doesn't work the number gets wrote down in my log book.

If a mag doesn't work it gets trashed.....

I use poor functioning mags for my dry work with reloads, etc so I'm not repeatedly beating up on a good mag.

I number all my mags, either with an engraving pin, or with white enamel paint on more valuable collector pistol mags.

But an AR mag that failed to work in any gun would get run over by my truck on the way home.

Dry erase marker?
However, I don't mind if my mags have a little + on them, so a Sharpie would be my go-to marker.

I have used one of those black in color, waxed penciles.
It rubs off with solvent like, gun cleaning solvent, paint solvent, brake clean, electramotive, carbcleaner...

Dr. , not to steal your post..but, have you had many mag. related problems with your AR? I think I remember one FTF ( Federal 40gr Blitz ammo, jammed that bullet clear back into the case ) in my 20+ years with my AR.

Just curious.
