.21889 inches is basically .22 or a 22 caliber bullet (at least in the US). Caliber is usually the diameter of the bullet in inches, normally referred to without the decimal point. An M-16, or any other modern military gun, would be designed to optimize things such as the weight of the gun and the ammunition, stopping power, the action of the bullet when hitting flesh, imparting maximum energy to the target (instead of passing through), and a host of other factors. Guns are not designed to accept a round unit bullet, the size of the bullet is determined by desired performance. The result is usually odd unit dimensions in both inches and mm.
