Since 1997,[2] the Nevada corporation has designed, developed, and manufactured military small arms, machine guns, and replacement parts.

Ordnance specializes in producing versions of the mature, combat-proven Mk43/M60E4 and M2 machine guns, making and testing them according to U.S. military technical specifications and instructions.

A U.S. government representative is on site to witness and verify specific procedures in the production and testing of the weapons, and ensure all the required standards are met.

[citation needed] The company ensures that all of its Mk43 and M2 improvements are backwards-compatible and that its M2 spares and components interchange with those from Maremont Corp. and Saco Defense.

[citation needed] The company also uses a magnetic particle inspection machine for detecting surface and subsurface irregularities in the metal of its weapons.

Called cryo for short, the process involves cooling the steel to about minus 300 degrees Fahrenheit, which increases the martensite content in its crystalline structure.

Ordnance packaging conforms to the military preservation, packing, and marking requirements of the current Mil Standard.

[citation needed] Each weapon has a unique serial number, which means that all of the raw materials that went into making each one can be traced to their origins.

[citation needed] Once a weapon is completed, tested, and approved by Quality Assurance, it is packaged, labeled, and marked according to the current Mil Standard.
