I'm not sure I ever heard of a SS cleaning rod. However, if you have them, consider a muzzle guide.

I believe they were originally invented to handle rifles which cannot be cleaned from the chamber end, such as the M-1 Garand and M-1 Carbine. Midway has models for AR-15 HBARs and for those which have flash suppressors.
I use a one-piece teflon coated rod made by Dewey. I always feed it from the chamber end after removing the bolt carrier. Bore guides also exist for use from the chamber end for those who are adamant about avoiding barrel damage.
I also use bore snakes, especially while at the range. I always put a wet coating of CLP in my bore as a final cleaning step, and I use the bore snake to clean it out before I commence fire. While some believe they do not do as good a job brush-wise as a rod and brush, I find them handy when I'm spending a lot of time at the range and want to do a periodic quick cleaning. The big advantage they do have is the incredible amount of soft material area, something like 40 or 50 patches worth, which you get in one shot. To keep them clean I just run them periodically thru the dish washer in the plastic basket for small items on the utensil rack.
