The company's first original design, the Dye Matrix 4 (DM4 for short.), was released in 2004. The spool valve design introduced Dye's patented spool valve technology and instantly cemented the company as a staple in the high-end paintball gun market. As the years went on, Dye would continue to push the boundaries of high-end paintball gun design, while also developing mid-range paintball guns for rookie and novice players.
