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.

Countersunk self-drilling screws are a specific type of screw designed to allow for a flush finish in various materials, including wood, metal, and plastic. The term countersunk refers to the conical shape of the screw head, which allows it to sit seamlessly against the surface of the material being fastened. This design is particularly advantageous for aesthetics and functionality, as it eliminates any protruding heads that could be prone to snagging or catching on other objects.
