Lee-Enfield Rifle

The fastest military bolt-action rifle of its day, serving the British Empire and Commonwealth for over six decades.

The Lee–Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the standard service rifle of the British Armed Forces from its official adoption in 1895 until 1957.

Lore & Background

A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded it and the earlier Martini–Henry and Martini–Enfield rifles.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, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars (such as Australia, New Zealand, South Africa, and Canada). Although officially replaced in the United Kingdom with the L1A1 SLR in 1957, it remained in widespread British service until the early/mid-1960s and the 7.62 mm L42A1 sniper variant remained in service until the 1990s. As a standard-issue infantry rifle, it is still found in service in the armed forces of some Commonwealth nations, notably with the Bangladesh Police, which makes it the longest-serving military bolt-action rifle still in official service, having outlasted the Mosin–Nagant. Total production of all Lee–Enfields is estimated at over 17 million rifles. The Lee–Enfield takes its name from the designer of the rifle's bolt system—James Paris Lee—and the location where its rifling design was created—the Royal Small Arms Factory in Enfield.

Reader's Guide

The Lee–Enfield rifle was derived from the earlier Lee–Metford, a mechanically similar black-powder rifle, which combined James Paris Lee's rear-locking bolt system that had a barrel featuring rifling designed by William Ellis Metford. The bolt has a relatively short bolt throw and features rear-mounted lugs, and the bolt operating handle places the bolt knob just rearwards of the trigger at a favourable ergonomic position close to the operator's hand. The action features helical locking surfaces (interrupted threading). The rifle was also equipped with a detachable sheet-steel, 10-round, double-column magazine. To further facilitate rapid aimed fire, the rifle can be cycled by most riflemen without loss of sight picture. These design features facilitate rapid cycling and fire compared to other bolt-action designs like the Mauser. The Lee bolt-action and 10-round magazine capacity enabled a well-trained rifleman to perform the 'mad minute' firing 20 to 30 aimed rounds in 60 seconds, making the Lee–Enfield the fastest military bolt-action rifle of the day. The current world record for aimed bolt-action fire was set in 1914 by a musketry instructor in the British Army—Sergeant Instructor Snoxall—who placed 38 rounds into a 12-inch-wide target at 300 yards in one minute. The Lee–Enfield was adapted to fire the .303 British service cartridge, a rimmed, high-powered rifle round.

Did You Know?

The Lee–Enfield was introduced in November 1895 as the .303 calibre, Rifle, Magazine, Lee–Enfield, or MLE.
The best-known Lee–Enfield rifle, the SMLE Mk III, was introduced on 26 January 1907.
During the First World War, the SMLE Mk III was found to be too complicated to manufacture, and in late 1915 the Mk III was introduced with several simplifications.
