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