  1. On my last TDY into Afghanistan in 2012, I took a small vial of Tungstendisulphide powder, chemical name WS2, to try as a dry lubricant for the mil connectors on our C4i radio equipment. A USMC Gunny and I was eating lunch at a DFAC at a FOB and started talking about firearms. I mentioned to him that NASA uses WS2 as the lubricant for the MARS rovers, and that I had started lubing my AR15/Sig/Browning HP, motorcycle, and so forth with it with GREAT success.

    I described to him how I use a Q-tip to burnish the blackish/grey powder on the bolt carrier group parts, and any place that has sliding friction. He asked me if I would leave what I brought with him.

    Degrease the surface, burnish with the WS2, and then re-lube with whatever you normally use if you must for rust protection. But try dry first 😉 My chainsaws were burnished and the bars run cooler. There are many other applications besides weapons lube: vehicular, my French Horn valves! and so forth. (it wont come out of the tuxedo….)

    One excellent source of the powder and spray format (nasty solvents but necessary) is:

    WS2 makes molybdenumdisulphide and the original “graphite” obsolete.

    Boron-hex-nitride, HBN, is awesome for high temperature applications to 1000C (bullets….re-tinning copper)


  2. Decent three articles. I still use the old SLIP 2000 lube for my AR’s and pistols. Lube is like caliber discussions, everyone has got their favorites. I am wrestling though with the selection of the right handgun to carry on my duty belt. I like the 45acp and do well with it but like the author stated there has been advancements in 9mm ammo and I do enjoy shooting the G19.

  3. Thanks for the three great articles! My choice for practical use is my Browning High Power, even though my favorite is my 1911 made in 1943 by Remington Rand. The best lube I have found in 49 years of shooting (18 years competitively in combat and PPC) and continue to use is EEZOX.

  4. There is not a need to practice “ tap and rack” with a S & W model 66. It will shoot very straight if you do your part. A very good article. I enjoyed reading. The article makes some very good points.

  5. Lube?

    I can’t imagine anything being better than lubriplate engine assembly lubricant.

    Every scanario is different I guess, but for me and my training needs, I’ve yet to need anything more.

    It clings like grease, and as it gets hot it turns into a medium weight oil. So long as I’m not cooking off several hundred rounds at one setting, I can’t imagine there ever being a problem.

    God help me if ever I find myself in such a situation. Needing more than 200 rounds tells me I’m in a situation I should have seen coming, and I’m in over my head.

    Hello OPSEC!

  6. Good point about limp wristing. It is often overlooked as a cause of malfunctions. There is a video on youtube where the shooter takes a reliable handgun and intentionally causes it to misfire every time.

  7. I’m sure there is more than 1 good choice for gun lube under normal conditions. It was research into cold weather lubricants that led me to slip 2000 ewl. I have used it at 10 below zero and the guns ran flawlessly.
