Magazine Lee-Enfield Mk1

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 with a barrel featuring rifling designed by William Ellis Metford. Experiments with smokeless powder in the existing Lee-Metford cartridge seemed at first to be a simple upgrade, but the greater heat and pressure generated by the new smokeless powder quickly wore away the shallow, rounded, Metford rifling. Replacing this with a new square-shaped rifling system designed at the Royal Small Arms Factory (RSAF) Enfield solved the problem, and the Lee-Enfield was born. The fast-operating Lee bolt-action and large magazine capacity enabled a trained rifleman to fire between 20 to 30 aimed rounds a minute, making the Lee-Enfield the fastest military bolt-action rifle of the day.
Originally, the concept of a detachable magazine was opposed in some British Army circles, as some feared that the private soldier might be prone to lose the magazine during field campaigns. Early models of the Lee-Metford and Lee-Enfield even used a short length of chain to secure the magazine to the rifle. Critics also predicted that a repeating rifle with such a large magazine capacity would discourage soldiers from taking careful aim, relying instead on sheer volume of fire to repel the enemy. Both of these concerns were proved to be unfounded.
