How a Lee Enfield works

The Lee–Enfield is a bolt-action, magazine-fed, repeating rifle that served as the main firearm used by the military forces of the British Empire and Commonwealth during the first half of the 20th century. It was the British Army’s standard rifle from its official adoption in 1895 until 1957. It is often referred to as the “SMLE,“ which is short for the common “Short Magazine Lee-Enfield“ variant. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded the earlier Martini–Henry, Martini–Enfield, and Lee–Metford rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard issue weapon to rifle companies of the British Army and other Commonwealth nations in both the First and Second World Wars (these Commonwealth nations included Australia, New Zealand, Canada, India and South Africa, among others).
