Printed is a good idea I neglected to mention that in my comment as an option. I’ve got a cloud defensive set-up on a gun that takes the equivalent of one 12 o’clock and one 9 o’clock mlok slot.
But I wouldn’t recommend using any laser or light from pre 2010 because doubtlessly someone(s) buying them to clone some obscure setup and they only ever made a limited production run.

YSK call your house rep. They’re more likely to answer. Also call your state reps first. Most issues are handled on a state level, not federal, and state house reps tend to be the most accessible.
