E Pluribus Unum

The M4A1 follows a modular design philosophy, and continues to improve on the foundation of M16A2's M4 variant as a carbine weapon. My primary use is in the arsenals of Special Forces. Although I've had a tumultuous adoption history, my light weight and close-range stopping power eventually led to my popularity on many battlefields. War is ever changing.-M4A1 (Warning: Complete AU)
