Its not difficult to make a gun oil rag. An old cotton shirt will do just fine. Wash and dry the old shirt (no fabric softener please), then cut a square about 12"x12" add some oil to it and wipe down your weapon. Do not throw away the rag. Instead, fold it up and put it in a zip lock bag. Next time you wipe down your weapon, add a little oil to the rag and wipe down again. Fold the rag back up and put it back into the zip lock. After a few applications, you will not have to re oil the rag for quit a while. My wipe down rags are kept in my rifle and pistol hard cases.
No such thing as a stupid question. What is stupid is not asking it.
