MKII magazine bumbers or pad extensions?

All,

I am looking for a set of magazine floor plates/base pads that are made out some type of plastic and are either red or orange.

Working on a biathlon rifle build, but, having a tough time finding a base pad that would make it easier to find them if they get dropped.

Thoughts?

What if you simply spray painted the entire magazine blaze orange or some other bright color?
You could fabricate bumpers out of large pencil erasers and glue them on the bottom of the mags if you wanted.
