query: What is the Heckler & Koch XM8?
answer: The Heckler & Koch XM8 is a lightweight assault rifle system developed in the late 1990s and early 2000s.  It was designed as a modular system with various configurations, from a short-barreled personal defense weapon to a support weapon. While considered by the US Army as a potential replacement for the M4 carbine, the project was ultimately canceled.  The Royal Malaysian Navy's PASKAL special forces adopted the weapon.
