When the British military transitioned form the .303 British cartridge to 7.62mm NATO in the 1950s, it replaced the Enfield rifles with the new L1A1 SLR (the FAL) but retained the Bren gun as a support weapon. The Bren was updated to use 7.62mm, in a process more complicated than most people would think. Ultimately, only a few thousand L4 series Brens were made, as they were rather quickly supplanted by the FN MAG as a belt-fed support weapon. This particular one is marked for the South Africa Forces and dated 1970. Action, Barrel and rear sights are marked 7.62. Good Overall Condition with usual wear.
