During 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 Mk VI, but stronger and most importantly, 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 and the charger bridge was no longer rounded for easier machining. 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 line like other aperture sight lines proved to be faster and more accurate than the typical mid-barrel rear sight elements sight lines offered by Mause.
