Gun cleaning products are constantly undergoing change so I can't recommend any specific product as being the most popular. Suffice to say, in my experience, all these products work if they are specific to gun cleaning. I will recommend staying away from steel cleaning rods and go with those made of softer metals or carbon. Also, for rifles, a bore guide specific to your rifle is a handy tool to have. I clean after every range session and I'm still using cleaning rods, brushes, solvents, and gun oils but then I'm also a very senior shooter.
