Lee-Enfield
The Lee-Enfield was the British army's standard bolt action, magazine-fed, repeating rifle from 1895 until 1956. In various marks it was standard army issue for the first half of the 20th century, a momentous period which saw two world wars and the loss of Britain's empire. It fired the British .303" rimmed (7.7x56R) centrefire round (photo) from a ten-round detachable box magazine, fed from stripper clips.The rifle was derived from the earlier Lee-Metford, a physically similar black powder design which combined James Paris Lee's rear-locking bolt system with a rifling system designed by William Ellis Metford. Lee's action was a major improvement on existing bolt-action designs. The rear-mounted lugs placed the operating handle much closer to the operator, over the trigger, making it much quicker to operate than "traditional" designs like the Mauser, which forced the operator to move their hand forward to operate the bolt. The speedy bolt and large magazine capacity ensured that a trained rifleman could fire 15 aimed rounds a minute, making the Lee the fastest military bolt action rifle of the day.
Experiments with smokeless powder in the existing Lee-Metford cartridge seemed at first to be a simple upgrade, but the greater heat and pressures generated by the new cartridges proved to wear out the shallow, rounded, Metford rifling. Replacing this with a new square-shaped rifling system designed at Enfield solved the problem, and the Lee-Enfield was born. The government demanded that the new design use the existing, rimmed, cartridge, a decision which ensured that the .303 British survived well into the age of rimless cartridges.
The rifle was introduced in 1895 as the .303 caliber, Rifle, Magazine, Lee-Enfield, or more commonly simply Magazine Lee-Enfield, or MLE. The next year a shorter version was introduced as the Lee-Enfield Cavalry Carbine Mk.I, or LEC, with a 21.2 inch barrel as opposed to the 30.2 inch one in the "long" version. Both underwent a minor upgrade series in 1899, becoming the Mk.I*'s.
In 1902 a carbine version of the original was introduced, the famous Short Magazine Lee-Enfield, or SMLE, (pronounced Smelly). The barrel length was now half-way between the original and the carbine, at 25.2 inches. The SMLE's visual trademark was its blunt nose, the end of the barrel having shrunk into the stock. The shorter length was controversial at the time, many influential thinkers believing that it was neither short enough for horseback use nor long enough for accurate long-range fire. A replacement was sought.
During the Boer War the British were faced with accurate long-range fire from the famous Mauser rifles, model 1895, in 7x57mm caliber. This smaller, high-velocity round prompted the War Department to develop their own "magnum" round in 1910, using a .276 calibre round patterned off the Ross rifle. A modified version of the SMLE was built to fire it, the Pattern 1913 Enfield, although nothing came of this. Adapating the same mechanism to fire the standard .303 round led to the Pattern 14 Rifle, or P14, a competent design fed from a five-round internal magazine. Effective mass production was still a way off when World War I started, and the P14 was dropped. Thus the SMLE remained the standard British rifle during World War I and into World War II. In 1926 the British Army changed the nomenclature and the SMLE became the Rifle No.1 Mk.III, with the original MLE and LEC becoming the Mk.I and Mk.II. The P14 went into production in America as the Enfield M1917, and enjoyed some success as a compliment for the Sprinfield M1901 rifles which were America's standard issue; furthermore, the P14 was used in Britain as a rearguard rifle, latterly to equip the WW2 Home Guard (the soldiers of 'Dad's Army' carry P14s).
The SMLE design was fairly difficult to manufacture because of the many forging and machining operations required. In the 1920s several experiments were carried out to help with these problems, reducing the number of complex parts. The No.1 Mk.V used a new receiver-mounted sighting system, which moved the rear sight from its former position half-way up the barrel. The increased gap improved sighting accuracy. The No.1 Mk.VI also introduced a "floating barrel" which was not connected strongly to the stock, allowing the barrel to move with the expansion and contraction of heating without changing the bedding forces, and thus accuracy. Small numbers of rifles were also built with an experimental semi-automatic loading system.
In 1939 the need for new rifles grew, and the Rifle, No.4, Mk.I was adopted, although but widespread production did not start until 1941. The No.4 was similar to the Mk.VI, but included a new adjustment system for setting the "headspace", the spacing between the front of the bolt and rear of the receiver. Unlike the SMLE, the No.4 did not have a blunt nose, the barrel protruding some way from the stock. The new floating barrel improved accuracy, and the No.4 became the most common sniper rifle in the British forces, fitted with a 3x scope. Known as the No.4 Mk.1(T), many were re-barreled after the war to the new 7.62 NATO round and continued in service until the early 1980s as the L42.
Later in the war the need for a lighter, shorter rifle for use in the jungles of the far East led to the development of the Rifle, No.5, Mk.I "Jungle Carbine". With a severely cut-down stock and a prominent flash hider, the design was somewhat shorter and 2lb lighter. Despite a rubber butt-pad, the .303 round produced too much recoil for the lightweight rifle to be a complete success, and the cut-down stock caused the rifle's point-of-aim to wander over time.
In total over 14 million Lee-Enfields had been produced in several factories on different continents when production in Britain shut down in 1956, at R.O.F. Fazakerly. Contributing to the total was the arsenal at Ishapore in India's, which continued to produce the Enfield in 7.62mm until the early 1970s. The original site of Birmingham's Royal Small Arms Factory in Enfield has subsequently been demolished and replaced with a housing estate. Some of the original buildings have been converted and evidence of the works are still visible.
The Lee-Enfield was replaced in front-line service with the FN FAL-dervied L1A1 SLR in 1955, although it continued for a few years as a training and drill weapon; those who undertook National Service were trained with the Lee-Enfield. However, the aforementioned L42 sniper rifle continued as the British Army's standard sniper weapon until the early 1990s, being replaced by Accuracy International's AW/L96.
Lee Enfields are still used by reserve forces and police forces in many Commonwealth countries, particularly India. During the Soviet invasion of Afghanistan it became apparent that many Afghan tribesmen were still armed with Lee-Enfields, which remain effective weapons in a desert environment, where long-range accuracy is more important than volume of fire.
Lee Enfields are very popular hunting rifles. Many surplus Commonwealth rifles were sold in the US, Canada and Australia, and they are prolific in Southern Africa with hunters, farmers and sportsmen. A goodly number have been 'sporterised', having had the front furniture removed and a scope fitted so that they resemble a sporting bolt rifle. Top notch accuracy is very difficult to achieve with the Lee Enfield design due to the loose chamber - designed primarily to work in adverse conditions - the two part stock, and the bolt's rear locking lugs, and thus the Enfield is overshadowed by derivatives of Paul Mauser's design as a target shooting weapon.
