Description
The L2A1/C2A1 (C2) is a light machine gun based on the L1A1 Self-Loading Rifle (SLR), the British version of the Belgian FN FAL battle rifle..
Differences from the L1A1/C1 include a heavy barrel, squared front sight (versus the "V" on the semi-automatic models), a handguard that doubles as a foldable bipod, and a larger 30-round magazine although it could also use the normal 20-round magazines. Only Canada and Australia used this variant. Australia, New Zealand, and the United Kingdom used the Bren light machine guns converted to fire the 7.62×51mm NATO cartridge for use in the support role.
The Australian Lithgow Small Arms Factory produced about 10,000 L2A1 rifles between 1962 and 1982.
