The 6 mm SAW describes an experimental series of cartridges developed in the 1970's for the US Army. The cartridges were produced in a variety of sizes and from a variety of materials. The intent was to develop a cartridge that would replace all 5.56x45mm NATO weapons as well as most 7.62x51mm NATO rifles and machine guns in the US military. Eventually, the 5.56 mm was retained and only the machine gun portion of the SAW (Squad Automatic Weapon) competition was successful. That program led to the M249 Squad Automatic Weapon.

Note that the dimensions listed to the right are for 6x45mm SAW rounds.[1] Three version were produced for testing in the early 1970s. An aluminum-cased version was developed, as well as the 6 mm SAW Long which was slightly longer (by about 5 mm)[2]
