The Lee–Metford is a British bolt action rifle which combined James Paris Lee's rear-locking bolt system and detachable magazine with an innovative seven-groove rifled barrel designed by William Ellis Metford. It replaced the Martini–Henry as the standard service rifle of the British Empire in 1888, following nine years of development and trials, but remained in service for only a short time until replaced by the Lee–Enfield.

Bolt-action is a type of manual firearm action that is operated by directly manipulating the bolt via a bolt handle, most commonly placed on the right-hand side of the firearm. The majority of bolt-action firearms are rifles, but there are also some variants of shotguns and handguns that are bolt-action. A firearm using bolt-action mechanism is colloquially referred to as a bolt gun.
