D3 Research LLC is a small business specializing in gunsmithing and firearm customization based out of Puyallup, WA. Started in 2017, our background is in mechanical and R&D work. Rich has an associate degree in mechanical design and drawing along with 11 years’ worth of experience in R&D machining and destructive testing (yes, it is as fun as it sounds). Lisa also has an associate degree in mechanical design and drawing as well as a BS in mechanical engineering from Sacramento State. Lisa is a licensed professional mechanical engineer with both construction and manufacturing experience.

Our goal as a business is to help our customers express themselves and improve their shooting experience by way of customization, repair, or upgrade. We pride ourselves not only being able to create a high-quality product, but one that is also uniquely yours. We take the time to work with each and every one of our customers to help make your own unique statement. From custom designs to custom finishes, we have the skills and expertise to make your custom firearm a reality.

We offer a wide variety of services, including custom coating, custom design, repair, modification, and refinishing. We can coat almost anything metal, most hard plastics, even wood. As a KG Endorsed Applicator, we prefer KG Gun Kote for our custom coating projects. However, we are able to apply Cerakote and DuraCoat on request. Along with helping our customers personalize their firearms, we are also able to customize cups, knives, and just about anything else we can fit into our oven. We also can help in the research and development of new products, including assistance with custom tools and fixtures, experimental or testing setup, and prototyping.
