The SA80, or Small Arms for the 1980s, is a British bullpup assault rifle designed for the British Armed Forces. It was first introduced in the 1980s and features a compact design, with the action and magazine located behind the trigger. This configuration allows for a shorter overall length while maintaining a standard barrel length, making it easier to handle in close quarters. The SA80 is chambered for the 5.56×45mm NATO cartridge and is known for its accuracy and reliability. It has undergone several upgrades since its initial release, including improvements to its L85A2 variant, which enhanced its performance in various combat situations.
