The SA80 (Small Arms for the 1980s) is a British family of 5.56mm small arms. It is a selective fire, gas-operated weapon. SA80 prototypes were trialled in 1976 and production was completed in 1994.
The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the SLR L1A1 variant of the FN FAL. The improved L85A2 remains in service today. The remainder of the family comprises the L86 Light Support Weapon, the short-barreled L22 carbine and the L98 Cadet rifle.
The SA80 was the last in a long line of British weapons (including the Lee-Enfield family) to come from the national arms development and production facility at Enfield Lock. Its bullpup configuration stems from a late-1940s programme at Royal Small Arms Factory Enfield to design a new service rifle which was known as the EM-2, which though similar in outline, was an entirely different weapon.
