Also known as: SLR, Self-Loading Rifle, L1A1, L2A1, The Slur
Overview
The L1A1 Self-Loading Rifle (SLR) is the Australian-manufactured, inch-pattern variant of the Belgian FN FAL battle rifle, produced under license at the Lithgow Small Arms Factory in New South Wales from 1959 to 1986. Chambered in 7.62x51mm NATO, the L1A1 was the standard-issue infantry rifle of the Australian Defence Force for nearly three decades, serving through the Malayan Emergency, Indonesian Confrontation, Vietnam War, and numerous peacekeeping operations. Unlike the original FN FAL which featured selective fire, the Australian L1A1 was semi-automatic only, a deliberate design choice shared with the British variant to enforce fire discipline and conserve ammunition in combat. The rifle utilized a short-stroke gas piston system with a tilting breechblock, feeding from 20-round detachable box magazines. With its powerful 7.62mm NATO cartridge, the L1A1 earned a fearsome reputation for stopping power and reliability in the jungles of Vietnam and Borneo, where Australian soldiers consistently favoured it over the lighter American M16. Approximately 220,000 L1A1 rifles were manufactured at Lithgow before the weapon was replaced by the F88 Austeyr (a licensed Steyr AUG) in the late 1980s.

Notes
The Australian L1A1 was based on the British L1A1 pattern, itself derived from the FN FAL but re-engineered to imperial (inch) dimensions rather than the original metric specifications. This meant that inch-pattern L1A1 magazines and some components were not interchangeable with metric-pattern FAL rifles, a logistical consideration in coalition operations. The L2A1 heavy-barrel variant served as a section automatic weapon with a bipod and 30-round magazine capability, filling the light machine gun role until replaced by the FN Minimi (F89). The Australian SAS Regiment famously created unauthorized field-modified variants known as 'The Bitch' by cutting down L2A1 heavy-barrel rifles and mounting XM148 grenade launchers. The rifle's wood furniture was standard on early production models, with some later examples receiving polymer handguards. The L1A1 was replaced in Australian service from 1989 onwards by the F88 Austeyr under Project Wundurra, though some reserve and cadet units retained the SLR into the early 1990s.
Background
Australian soldiers in Vietnam overwhelmingly preferred the hard-hitting L1A1 SLR over the American M16, trusting its powerful 7.62mm NATO round to drop enemies with a single hit. The Australian SAS Regiment created unauthorized field modifications known as 'The Bitch'-cutting down L2A1 heavy-barrel variants and mounting XM148 grenade launchers, creating an improvised assault weapon decades before modern compact battle rifles.
