p14 enfield
The Pattern 1914 Enfield or (The Rifle, .303 Pattern 1914 (or P14)) was a British bolt action rifle that was to replace the lee-enfield as standard-issued weapons for infantry, but was sidelined by its predecessor weapon, only produced in limited numbers during the First World War period. The weapon was developed as an hybrid rifle with a Mauser-like, cock-and-closing action and internal-box 5-round magazine, with an Enfield-style safety (on the opposite side of the receiver compared to the Enfield) and a cock-on-closing mechanism with a new and greatly improved sight.
On the other hand, when the Americans entered the war in 1917, the Army realized that it couldn't get its hands on enough M1903 Springfields to equip their infantry, so they had to acquire and produced their version of P'14 rifle, M1917 Enfield from private companies who was previously producing for the British, such as Remington, Winchester, and Eddystone, until enough M1903s was being sufficiently produced to equip the rest of the expeditionary force in the western front of the war.
