Pattern 1913 Enfield

The Pattern 1913 Enfield, often called the P13, was an experimental bolt-action rifle developed by the Royal Small Arms Factory at Enfield for the British Army after its experience with Boer marksmen in the Second Boer War. It was meant to replace the Short Magazine Lee-Enfield and was built around a Mauser-style action and a new high-velocity rimless .276 Enfield cartridge that was more powerful than the .303 British round. A limited batch of rifles was made for troop trials in 1913, held in Britain, Ireland, Egypt and South Africa, and a few improved examples followed in 1914. Its features included a flip-up aperture rear sight, a low-profile bolt handle, helical locking lugs and a one-piece stock. The outbreak of the First World War made the change of cartridge impractical, so the design was adapted to the .303 round as the Pattern 1914 and later redesigned as the American M1917 Enfield.
