The Lee-Enfield rifle refers to an early model of the British Lee-Enfield rifle, specifically the "Long" Lee-Enfield Mk I rifle made around 1900, which featured a magazine cut-off and a dust cover on the bolt but lacked the charger loading system of later models. It was a successor to the Lee-Metford, incorporating a new five-groove Enfield rifling system designed to withstand the heat of the newly developed cordite propellant.
