You know what's amazing is if we ask 50 guys we'll get 45 different answers!!!

I use Rem Oil, but just because it's a bottle I had. I would probably buy CLP next. I used that on my AR15 in the military. My criteria would be that it lubricates, doesn't get sticky as it dries, and functions well in sub-zero weather. Some guys use grease??? Wow!

As for smell, I guess I kind of like Hoppes #9!
