The L403A1 is a 5.56x45mm NATO, gas-operated, magazine-fed rifle adopted by the British Armed Forces through the Alternative Individual Weapon Program. Built by the Knight's Armament Company, it is based on the AR-15 platform and features a free-floating barrel for enhanced accuracy, fully ambidextrous controls, and an M-LOK handguard for attaching accessories. Intended to replace the L85A3 in frontline service, the L403A1 is optimized for optical sights and modern soldier systems, ensuring full compatibility with current infantry gear.
