In the field I carry a take-down rod with a jag and soaked patches in case I get some debris in the barrel.
At the bench, I put together my own 'kit'.
Much like others have said, get a proper rod, bore guide, QUALITY patches, jag and brushes and make your own kit.
If you want to have some fun with this crowd, ask 'em for their favorite cleaning liquid. Previous posts on this last for pages
