Lee-Enfield No. 4 Mk. I

U.S. Property Savage made Enfield The Lee–Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the standard service rifle of the British Armed Forces from its official adoption in 1895 until 1957. By the late 1930s, the need for new rifles grew and the Rifle, No. 4 Mk I was officially adopted in 1941. The No. 4 action was similar to the No.1 Mk VI but stronger and easier to mass-produce. Unlike the SMLE, that had a nose cap, the No 4 Lee–Enfield barrel protruded from the end of the forestock. For easier machining, the charger bridge was no longer rounded. The iron sight line was redesigned and featured a rear receiver aperture battle sight calibrated for 300 yd (274 m) with an additional ladder aperture sight that could be flipped up and was calibrated for 200–1,300 yd (183–1,189 m) in 100 yd (91 m) increments. This sight, like other aperture sights, proved to be faster and more accurate than the typical mid-barrel open rear sight elements sight lines offered by Mauser, previous Lee–Enfields or the Buffington battle sight of the M1903 Springfield.
