The design of the M16 foundation bolt has evolved over the years, with improvements focusing on enhancing reliability and durability. Early versions of the M16 experienced issues with jamming and fouling, particularly in the harsh environments encountered during the Vietnam War. In response to these challenges, the foundation bolt was modified to incorporate better materials and improved engineering techniques. The introduction of a chrome-plated bolt carrier was one of the significant advancements, reducing friction, enhancing corrosion resistance, and improving overall cleaning ease.
