Custom finishes for AR-15 uppers not only provide aesthetic appeal but can also enhance durability and protection. The choice of finish depends on your preferences, intended use, and the environmental conditions you anticipate. Here are some popular custom finishes for AR-15 uppers:
1. Cerakote:
- Cerakote is a polymer-ceramic composite coating known for its exceptional durability and corrosion resistance.
- It comes in a wide range of colors and patterns, allowing for personalized designs.
- Cerakote can be applied to the entire AR-15 Parts receiver or specific components.
2. Duracoat:
- Duracoat is a firearm-specific finish that provides excellent rust prevention and wear resistance.
- It offers numerous color options and customization, including camouflage and stenciled designs.

- It provides a matte gray or black appearance and is suitable for military-style builds.
- While not as customizable as some other finishes, it offers excellent protection.
4. Anodizing:
- Anodizing is an electrochemical process that produces a durable, corrosion-resistant layer on aluminum.
- Type III hardcoat anodizing is commonly used for AR-15 uppers and is available in various colors, with black being the most popular.

When selecting a custom finish for your AR-15 upper, consider the intended use, the level of protection needed, and your personal preferences for aesthetics. Keep in mind that some finishes may have an impact on tolerances, so ensure your upper receiver components fit correctly after the finish is applied. Proper maintenance and care are essential to preserve the appearance and functionality of your custom finish over time.
