The SA80 is a British family of 5.56×45mm NATO small arms, all of which are selective fire, gas-operated assault rifles. The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 variant of the FN FAL. The first prototypes were created in 1976, with production ending in 1994. The A1 variant was significantly upgraded in the early 2000s by Heckler & Koch as the SA80A2 and remains in service as of 2018. The A3 variant was first issued in 2018 with several new improvements.
