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.

Best Lubricant

I have found that AR4400 is the best all-around lubricant for both AR rifles and 1911 pistols. I also noticed that all my firearms are much easier to clean after extreme usage. This is an outstanding lubricant and I highly recommend it!

Magic elixir for skeet shoot

Keeps everything smooth and clean longer.

like a new gun

This stuff has brought new life back into my 1920's J. P. sauer and Sohns pistol. slick, and glassy smooth with no jamming .Thanks for a great product.

AR4400 is a must!

I use this on my Heckler & Kochs. Doesnt take much. Alex recommended this to me and it works.

Great Stuff!

I've been using this for a few years now, and continue to do so because the results are impressive. Lots easier to clean everything I've applied it to after subsequent usage and there's no doubt, everything I've applied it to is definitely smoother running/working! Excellent for keeping rust off of bare metal after it has been thoroughly cleaned/dryed. I've applied it to cleaned threaded parts and, after 15 mins. of sitting lightly lubricated with this, they reassemble with a slickness that's very noticeable (after wiping away all the excess) . I've even used it to lightly coat lead pellets for an air rifle, (let them sit lightly coated in the oil and then wiped them off very well) and my chronograph showed a consistent 15% increase in velocity. No doubt it works similarly for lead bullets too. So many uses, and everything I've read about WS2 in tech papers seems to apply (thru my personal experience) with this product. This is NOT your father's "snake oil",..... This stuff flat out works (very well)! AND........ a little bit of this goes a long, long way too!
