Almost Adopted: The H&K XM-8 Family
The H&K XM-8 was a significant contender to replace the M4/M16, featuring a modular design with multiple barrel lengths and an integrated optic with laser/illuminator. Its AR-180 style gas system and polymer construction with a metal trunnion offered a modern approach. The rifle boasted ambidextrous controls and a unique paddle magazine release, showcasing advanced ergonomics for its time.
