Some Canadian C1s issued to naval personnel were also capable of automatic fire. Only Australia and Canada used this variant, as the UK and New Zealand used the Bren light machine guns converted to fire the 7.62mm NATO cartridge. Differences from the L1A1/C1 include a heavy barrel, a handguard that doubles as a foldable bipod, and a larger 30-round magazine although it could also use the normal 20-round magazines as well. However, there is also an automatic rifle variant, the L2A1/C2A1, capable of automatic fire and meant to serve in a support role. Most Commonwealth pattern FALs are semi-automatic only. Also, butt-stocks are not interchangeable, since the stocks on metric pattern and inch pattern guns attach in different ways. Despite this, many sub-assemblies are interchangeable between the two types, although components of those sub-assemblies may not be compatible. In contrast to the "metric" FALs, the design dimensions of the inch-pattern are British imperial units, rather than the metric units used in Belgium. It has seen use in the armies of Australia, Canada, Jamaica, Malaysia, New Zealand, Rhodesia, and the United Kingdom. The L1A1 Self-Loading Rifle, also known by the Canadian Army designation C1, as the SLR, or as the "inch pattern" FAL, is a British Commonwealth derivative of the Belgian FN FAL battle rifle, produced under licence.
