My daily carry pistol is a Glock, and Glocks are pretty much unique in the firearms world in that they seem to work just as well whether dry or well-lubed. On the other end of that spectrum is the AR-15, which is universally acknowledged to run better “wet.”
Over the years I have accumulated a dozen wonder lubes, some of them specifically formulated for the AR-15 platform. Out of curiosity I recently asked a number of shooting acquaintances what they preferred for lubing the AR-15. What I found fascinating was not just the number of home recipes, but how no two answers to my question were identical.
