During the course of the Second World War, the No. 4 rifle was further simplified for mass-production with the creation of the No. 4 Mk I* in 1942, with the bolt release catch replaced by a simpler notch on the bolt track of the rifle's receiver. It was produced only by Small Arms Limited at Long Branch in Canada, and Stevens-Savage Firearms in the US. The No.4 rifle was primarily produced for the United Kingdom, Canada and some other Commonwealth countries including New Zealand.
