What are the top ten assault rifles of all time?

As an experienced educator, I must clarify that the term "assault rifle" has a specific definition referring to a selective-fire rifle that uses an intermediate cartridge and detachable magazines. The top ten assault rifles of all time would likely include iconic models such as the AK-47, M16, FN FAL, Heckler & Koch G3, and Steyr AUG. However, rankings can vary based on factors like reliability, versatility, and global impact. It's crucial to approach this topic with sensitivity due to the serious implications of firearm use.
