The Millett story begins with Betty and Ray Millett, who founded Millett Industries in the mid 1970s. Ray had been an engineer at Cox model Airplane Company for a number of years, working with small, injection-molded plastic engine parts. From this process Ray developed the idea for the injection-molded steel parts that would pave the way for his many advancements within the gun industry. Millett Industries began when Ray purchased surplus cleaning equipment from an out-of-business clothing cleaner in Huntington Beach, California. He used the tanks and much of the plumbing from the equipment to develop a new process for manufacturing metal and ceramic parts. Together with a friend who was physicist, Ray perfected the process for making useable parts.
