Best Gun Grease – Any Gun

Why and where to apply grease vs. oil on firearms gunmetal regularly

Despite many manufacturers taking advantage of applying grease in the factory or in service, misinformation within the public audience stubbornly ignores the obvious smart move. Gun store staff not understanding the benefits and reasons for grease over oil doesn’t help.

First accept the premise that grease is not grease and oil is not oil. Different formulas have an impact or a lack there of well beyond consistency, but viscosity is a factor. Here are some critical comparative points:

  • Grease is meant for high-wear, slow moving gun parts like rails, trigger, seer pin, connector, bolt assembly and choke tube threads, to name a few.
  • A good gun grease, by nature, is an anti-seize material, so don’t get caught up in a product with that specific name. The right grease should be for any grease applications.
  • Grease offers more barrier material to counter the friction causing affects of sliding and banging of two gunmetal surfaces.
  • Synthetic grease is the choice of leading defense contractors for military applications for good reason. Test results prove it.
  • Nothing matches the benefits of a grease with a synthetic fluoropolymer additive that adds that extra level of protection.

With all of that, you do want to avoid being fooled by product marketing that has no basis in fact. Many companies claim things and rarely back it up. For example:

  • Military grade. What does that mean?
  • Packaging or even grease produced with really cool colors. So?
  • A product name that sounds cool, and does little else.
  • Performance claims that are rewritten almost word for word as if they were taken off the brochure of a brand with real credentials.
  • Very few companies actually make their grease vs. repackaged material from an intended use that has nothing to do with guns.

It is the nature of some people to constantly try new things, and then bounce out of it and off to the next flavor because they have yet again bought another “b.s.” product. They never learn.

Tetra Gun Grease has been on the market for almost 40 years and is respected and used consistently by reputable gunsmiths, armorers, factories and competitive shooters worldwide. There are some other reliable gun grease products out there, but not as many as you might think. Tetra is the original patented synthetic gun grease.

Oil or CLP (which is still an oil) is intended for inside the bore or the overall gunmetal body of firearms. By design, any oil is meant for faster moving parts and surfaces that need to be left with as little visible surface coverage as possible because you don’t want to interfere with ballistics.

Only grease can give you that extra coverage on the high wear surfaces as I already stated, and it should be respected as the lubrication partner to oil. You can still get by with oil or CLP throughout, but you should want the best results.

Grease is usually in solid form like in a tube or jar, but it could on rare occurrence be applied in a spray format like an aerosol only if it is engineered to be applied consistently. This idea is not easy to pull off. Either way, you want to polish it in to gun parts and wipe off excess, usually.
