The Rifle, .303 Pattern 1914 was a British service rifle of the First World War period, principally manufactured under contract by companies in the United States. It was a bolt-action weapon with an integral 5-round magazine. It served as a sniper rifle and as second-line and reserve issue, until declared obsolete in 1947. The Pattern 1914 Enfield was the successor to the Pattern 1913 Enfield experimental rifle and the predecessor of the U.S. Rifle M1917 Enfield.

The M1917 Enfield, the "American Enfield", formally named "United States Rifle, cal .30, Model of 1917" is an American modification and production of the .303-inch Pattern 1914 Enfield (P14) rifle, which was developed and manufactured during the period 1917–1918. Numerically, it was the main rifle used by the American Expeditionary Forces in Europe during World War I. The Danish Sirius Dog Sled Patrol on Greenland still use the M1917, which performs reliably in Arctic conditions, as their service weapon.
