100% Synthetic Firearm Lubricant and Protectant

We found the missing elements on all your well known gun maintenance products and improved them. Almost no attention was given to active anti-corrosion agents and low temperature performance. True synthetics also improve performance to the point which makes the firing action feel like you bought a new unit or as I say “better than new”.

Protection and Dependability for Generations

Dependable Firearm Performance

Firearm LubricantHunters and recreational shooters need their guns to perform when called upon, sometimes after an extended period of storage, after sitting for hours in a wet duck blind or while on a remote hunting trip with few opportunities to clean their gun daily. Since nothing will ruin a hunting trip or day at the range quicker than a malfunctioning firearm, AMSOIL firearm products were tested in a variety of firearms typically found at the range and in the field. The information gathered, along with extensive testing in the AMSOIL chemical lab, resulted in products dialed in for outstanding firearm protection in the most demanding conditions. As seen in the images, AMSOIL firearm products guard against damaging corrosion, helping keep firearms working properly for generations.

Best firearm lubricant

By  CHARLES,  a  Verified Buyer  on  December 31, 2020

I am a firearm instructor and this lubricant is the best I have ever used on firearms. By far super quality and lasting lubricant.

Like knowing it’s 100% synthetic

By  T Davidson FMX,  a  Verified Buyer  from  Ontario Canada  on  October 15, 2020
Works very good and actually sticks to metal where it counts (metal on metal) and doesn’t dry up. Keeps areas that see fouling cleaner than other oils.

All my guns are getting AMS’d

By  James,  a  Verified Buyer  on  September 10, 2019

I have clean several firearms with regular cleaners and lubricants, then I have cleaned with the AMSOIL product. There is a distinct difference in how the firearm behaves after cleaning and lubricating with your product. I notice the metal to metal sliding action is MUCH quieter and much more smooth. The AMSOIL product also lasted longer in storage that the conventional lubricant. The conventional lubricant left behind a residue that no longer provided metal to metal protection.

Quality firearms lube

By  Jerry,  a  Verified Buyer  on  June 13, 2019

Another great Amsoil product for shooting sportsmen and women. I use the liquid lube and put a light coat on the moving parts. This product has a great penetrating viscosity and I’ve come to use it for many different applications besides firearms.

Fantastic lube

By  Mistercedric,  a  Verified Buyer  from  Fort St. John  on  June 08, 2019

Extremely pleased with this product have a M4 Colt and this is excellent for lubrications

Firearm cleaner and lubricant

By  T,  a  Verified Buyer  from  Central Alberta, Canada  on  May 13, 2019

The cleaner removes fouling very fast and leaves a film of protectant/lube behind. I don’t have to use as many patches with this cleaner. The lubricant seems to work well, a semi auto shotgun I own that doesn’t like target rounds hasn’t jammed once with this lubricant. Looking forward to cold weather to see how it performs.

I would and will purchase this product again!

By  Freon Jocky,  a  Verified Buyer  from  Broken Arrow, OK.  on  February 27, 2019

Used my deer hunting rifle for the first time this season in probably 5yrs. Cleaned the gun and lubed it up with the new 100% synthetic firearm lube and it worked flawlessly. Use it on my revolver and my semi automatic pistols as well. Great product.

I will use this lubricant for a long time!

By  James,  a  Verified Buyer  from  Washington  on  February 14, 2019

Great synthetic lube for all my firearms after cleaning with Amsoil cleaner! Works and lasts as well as my Amsoil synthetic oil I use in my Camaro! I might add I only use the best in my Camaro and my firearms!
