Just as the title says let's hear what your you carry I've seen from the simple stuff and some that looks like they cleaned their safe out lol
The following items live in my range bag at all times:

Safety glasses (2) (same reason)
Break Free CLP
Uplula Magazine loader
Cleaning rod, brush, jag, patches, shop rag
Safariland belt hook for hearing protectors
Assortment of tools that I have needed for simple jobs on the range (I have learned by experience and added over the years) including screwdrivers, punches, Glock disassembly tool, hex keys, torx wrench, Wilson (I think) folding tool for 1911s, bushing wrench, front sight tool for AR; etc.
Although no longer used, I keep a few full moon clips and a tool to remove brass from the full moon clips.

I have a separate bag for ammunition.
