Smith Enterprise Inc. was founded as Western Ordnance in 1979 by Richard Smith in Mesa, Arizona, and the company made numerous types of rifles, but specialized in the M1 Garand and M14. In 1993, Western Ordnance reformed as Smith Enterprise and has built and rebuilt numerous M14 rifles for the US military and the militaries of Colombia, Canada, and other nations. The U.S. Department of Defense contracted with Smith Enterprise to build and modify M14 rifles for use by soldiers, marines, and sailors in Iraq and Afghanistan. Smith Enterprise played a major part in the M14 rifle modernization projects for various US military units, which resulted in the development of the U.S. Navy Mark 14 enhanced battle rifle (EBR). The company's history included originally making forged receivers for M14 rifles and briefly switching to investment casting. Smith stopped making receivers for a few years, but re-entered the market with receivers machined from bar stock in 2002. In 2003, Smith Enterprise Inc. created its version of the M14 EBR known as the Mk14 Mod 0, type SEI. The rifle used a medium heavy-weight 18-inch barrel and was used as a basis to create the US Navy's Mark 14 Mod 0, with Springfield Armory, Inc. being asked to supply the necessary machinery in cooperation with the Naval Surface Warfare Center Crane Division. SEI builds an improved M14 gas cylinder as a component of their specialized rifles and for the military to upgrade older rifles. The gas cylinder is assigned the NATO stock number: NSN 1005-00-790-8766. Springfield Armory, Inc.
