L42A1 ENFIELD (U.K.) - The L42A1 was a British Army sniper rifle chambered for the 7.62mm NATO cartridge which entered service in 1970. It served until replacement by the Accuracy International L96 in 1985. It was the last model in a long and famous line of Lee bolt action rifles using the rear-locking action designed by James Paris Lee to serve the British Army, which had first entered service in the Lee-Metford rifle of 1888. During its British Army service, the L42A1 saw active service during several conflicts including the Dhofar Rebellion in Oman, The Troubles in Northern Ireland, the Falklands War and Gulf War. The L42A1 was a 7.62Ã—51mm NATO conversion of the .303 British chambered Lee-Enfield No. 4 Mk1 and No. 4 Mk1 WWII-era British sniper rifles, which had remained in service for some time after the L1A1 variant of the 7.62mm FN FAL replaced the No.4 Lee Enfield as the standard service rifle in 1957.

FN FAL - Fusil Automatic Leger (Light Automatic Rifle) or FAL is a semi-automatic, selective fire battle rifle produced by the Belgian armaments manufacturer Fabrique Nationale de Herstal (FN). During the Cold War it was adopted by many North Atlantic Treaty Organization (NATO) countries, with the notable exception of the United States. It is one of the most widely used rifles in history, having been used by more than 90 countries. The FAL was predominantly chambered for the 7.62Ã—51mm NATO round, and because of its prevalence and widespread use among the armed forces of many NATO countries during the Cold War it was nicknamed 'The right arm of the Free World.'
