Had misfeeds on all 3 of my active weapons today. My instructor says they needed lubrication, and after oiling the mechanisms, they fed fine. As stated in another thread elsewhere: I clean my weapons until the materials are extracted without any black on them. I may be over-cleaning them, especially where it counts. In the Army, we used to apply thin coats of lubricant to parts and we certainly didn't have CLP that I can recall for general bore cleaning, though I use that now. I'm also a digital electronics technician from back in the early 1990s, and when working on VCRs, I used Marvel Mystery Oil to lubricate sensitive moving parts inside the main mechanism. So I am requesting input from anyone who will give it, especially active duty and veterans: what do you recommend for a general lubricant? Or can I ask for product names here? Would the Mystery Oil be suitable for a weapon?
