The M16A1 CANNOT use the SS109/M855 Ball round at all. The round's case neck is like 1/1000 of an inch too long. The very edge of the case "fire forms" into the leade (the part of the barrel where the bullet nose seats to the rifling) of the barrel throat, and causes MAJOR reliability issues in the M16A1 (like drive the expended M855 case out of the breech with a dowel rod issues). This is the reason the M16A1 was completely removed from Army service in 1992.

I figure there's mountains of M193 left, and a lot of the 855 has been shot off. Yes, wartime production, but the supply chain has gone to snot, so in many cases troops feel lucky to have ammo.
