The L85A1 is a British bullpup assault rifle that was introduced in the 1980s. It is chambered for the 5.56×45mm NATO cartridge and features a unique design where the action and magazine are located behind the trigger. This configuration allows for a shorter overall length while maintaining a standard barrel length, making it more maneuverable in tight spaces. The rifle is part of the SA80 family and has undergone several upgrades since its initial release. The L85A1 was primarily used by the British Armed Forces and has seen action in various conflicts. Its design has been both praised and criticized for its ergonomics and reliability.
