AR4400 Firearms Oil

Lubricates and Protects Against Wear and Corrosion

AR4400 LP is formulated with nano tungsten disulfide (WS2) which has been selected for its ability to bond immediately with metal alloys, filling in asperities to create a hard, dry, friction-reducing solid boundary lubricating film.


  • Lubricates and protects against wear with nano WS2
  • Lasting corrosion protection
  • Repels carbon, lead and copper deposits
  • Prevents galling and jamming

How it Works

Protects against wear by creating a resilient low friction surface composition

AR4400 LP firearms oil lubricates and protects against wear and corrosion. AR4400 LP is formulated with nano tungsten disulfide (WS2) which has an extremely low coefficient of friction (.03 dynamic and .07 static) and boasts a load carrying ability of 300,000+ psi effective from -450°F to over 1200°F.

Repels deposits

AR4400 repels carbon copper and lead deposits due to WS2's extremely low coefficient of friction, keeping your firearm cleaner for longer and allowing for fast easy and significantly less frequent cleaning.

Prevents galling and jamming

AR4400 will combat galling and jamming due to the reduction in deposit formation as well as the reduction in friction. Users have also reported faster and smoother action.

Lasting corrosion protection

AR4400 will repel moisture and combat corrosion in the most extreme environments.

Gun oil

As good as any gun oil, about the same price so I ordered when I got my last order, I'm liking the ar9100 though, starts alot better and seems to run better.

AR-15, 45ACP, 357 mag, Winchester 30-30 and Remington 1100 all feel smoother.

I completely stripped two AR’s and the rest of the gang above and after cleaning I lubed them all with AR4400-2. I’ve not been to the range but all weapons cycle smoothly and I’m sure that when fired I will be impressed with the performance. It also is excellent for oiling knives, especially automatic and spring assist models. I have 5 pre 2000 S&W collectible M&P automatics and they are so smooth, actually after using AR4400-2 they’re faster opening than ever. I also have a Ken Onion Kershaw 1550 blackout and it’s opening much better after oiling it.



Great Stuff

I have been using this gun oil for quite some time now. No failures while shooting. Also easier to clean weapon after shooting weapon.
Highly recommend!!!
