Lee–Metford
The Lee–Metford rifle (a.k.a. Magazine Lee–Metford, abbreviated MLM) was a bolt action British army service rifle, combining 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 rifle in 1888, following nine years of development and trials, but remained in service for only a short time until replaced by the similar Lee–Enfield.
