The Lee-Enfield No.4 Mk I is a British bolt-action rifle that served as the standard infantry weapon for British and Commonwealth forces during World War II and beyond. Officially adopted in 1941, it represented an evolution of the earlier SMLE design with simplified production methods, lighter weight, and improved aperture sights. The rifle features a distinctive cock-on-closing bolt action that allows trained soldiers to achieve rapid rates of fire up to 20-30 aimed rounds per minute. Chambere...
