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.

Slick Oil !

Superior lube that flows well.....Good Stuff !

New Formula?

AR4400 LP used to be thick, but this new formula is thinner. I use AR4400 for lubricating my firearms, I was surprised as the oil runs to my trigger finger while shooting. I never experienced this with the former AR4400 LP.
The new bottle is definitely smaller than before. As for the price I cannot say, whether this new one is pricier, since I forget how much the old one has cost.
I would try this again to other firearms and use definitely less, maybe only pat the oil instead of dropping it directly to the parts.
I really want to like this oil like the old one, but for the moment I still prefer the old one.

Great Stuff

I am a range master for a local police academy and firearms instructor and armor. Part of my duties is to maintain the academy firearms. This oil is fantastic it truly lubricants and embeds itself on to the metal. I tested the lubricant with a Colt 1911 70 series, fired 1000 rounds in 1 Day. Never stopped to clean the pistol during the test. The pistol never jammed or malfunctioned. After completing test I broke down the pistol to inspect and clean it. I was amazed how well the Lubricant maintained it’s consistency and remained on the metal parts that were lubricated. This is an excellent gun lube. I plan to conduct the same test on a Colt M4 carbine. I’ll keep you post on the results.
