Dye's machining operation was featured in a 2006 issue of Haas' e-zine "CNC Machining Magazine" in volume 10 issue 34. You can download the full issue here: (.PDF document)
The subject article describes Dave Youngblood's early crew and their entry into manufacturing by producing the long-lived Boomstick barrels on Haas equipment. Dye remained largley an accessory manufacturer until 2003, at which point they purchased the rights to the Gen-E Matrix marker, and began producing them on their own as the Dye Matrix (retconned referred to as the Dye DM3). This lead to the Dye DM4 marker release in 2004, which harroled a rather large expansion investment which would later result in the development of subsequent Dye and Proto products. It was at this time the Haas Magazine article was written.
While it's true that Dye no longer uses exclusively Haas products, and also no longer relies on exclusively US-based manufacturing, they do seem to spend a good aount of effort toward contract manufacturing through the same business that began as paintball-product only.

At the time this page was last updated, Dye's manufacturing operation is likely the highest-valued machine shop within the paintball industry. Smart Parts' former machine shop still holds the record as being able to out-produce any other company in terms of sheer quantity of finished products (likely by several times magnatude), however Dye Precision's current manufacturing facility is absolutely the current record-holder for high-value equipment and processes. Their use of select few multi-tasking machines is somewhat uncommon within the paintball industry; it's unlikely that these machines are used to produce paintball components, but instead allow Dye to cater to high-precision industries such as that of aerospace and medical.
