I was having a conversation with a neighbor about weapons cleaning the other day. He asked me if I had any spare oil, since he had just run out after a range day. The thought came to me, how many of us stock/prepare for such needs? We focus on having the weapon and ammo supplies. What are you/have you done to prepare for cleaning supplies, spare weapons parts and so on. This may not be SHTF, but it is a good dry run on how/what you are doing in regards to supplies, especially those regarding repairing and maintaining your firearms, knives and so on.
