Cerakote vs Anodize – Making the Best Decision for Your AR Lower

The finish you apply to your 80% lower is an important aspect. When you are researching your dream AR-15 build, you are bound to weigh the pros and cons of “cerakote vs anodize”. Hope by the end of this post, you will have more clarity as to which finish type is best for your specific needs and build. 

Cerakote vs Anodize

The job of a finish is to protect your lower receiver. It protects it from the elements, from abrasions, rust, and a whole heap or chemical solvents and cleaners. Finishing is a crucial aspect in a long lasting firearm. One of the interesting things about 80% lowers is that you can buy them raw. Raw means the aluminum receiver is unfinished and has that ‘shiny’ look to it. This unfinished 80% lowers are essentially a blank canvas for your wants and your weapon’s needs.

You generally have two options. The first option is you anodize and the second is Cerakote. Since the vast majority of receivers are aluminum, your options are somewhat limited, but even so, the options are excellent.

Anodizing 80 Lowers

Anodizing is what the majority of standard AR-15 80% lower receivers are finished with. Anodizing is an electrochemical process. Aluminum is the most common metal that is anodized, but titanium and magnesium can be anodized as well. Anodizing protects an 80% lower receiver from the environment, and is incredibly durable, corrosion resistant, and it can even be an aesthetic choice.

To anodize an 80% lower receiver you take it, and immerse it in a vat full of dangerous chemicals. More specifically this vat of dangerous chemicals is an acid electrolyte bath. Then, like Frankenstein’s monster, you apply an electric current to make the magic happen. The cathode is placed inside the vat, and a current is applied. The aluminum is your anode, and then, of course, you get oxygen releasing from the electrolytes. This combines with the aluminum atoms on the surface of the receiver. This is a complicated, and highly controlled form of oxidation.

Benefits of Anodizing Your 80 Lower:

  • More durable finish
  • Mil-spec (If Type 3 anodizing)
  • Longer lasting finish
  • Requires less maintenance
  • A cheaper finish to apply
  • Generally much longer lasting
  • Anodizing actually bonds to the aluminum

Cerakoting 80 Lowers:

Cerakote is an alternative form of finish for your 80% lower. It is somewhat new but has been around long enough to be established as a good product. It protects a lower receiver from the elements, is quite durable, and has become a standard option for some gun companies. Cerakote protects from bangs, dents, scratches, rust, and of course solvents and lubricants.

Cerakote is ceramic based finish that can be applied to a wider variety of materials, including aluminum, steel, plastic, polymer, and wood. It is applied via a spray. Typically a gun or gun parts would have to go through a long process to be ready to spray. However, a blank 80% lower is pretty much already ready to be coated. After the receiver is coated it most commonly need to be cured at a consistent temperature in an over.

Benefits of Cerakoting Your 80 Lower:

  • more customization for the end user
  • more tactical colors
  • dozens of options for different browns and greens

If you wanted to finish your weapon with camouflage options you could do so with Cerakote. You could also finish a weapon with crazy, alternating colors. Make it pink, blue, or any color you can imagine.

Whichever route you take, make sure you use a professional coating service. If you do anything less the finish can, and most likely will look terrible. It will be poorly done and not as resistant to wear and tear. So remember to be discerning when you choose the person doing the finish.

Which is Better?

There is not a clear answer to this question. This will really depend on what the end user needs. In some situations, anodizing will be the better option.
