What did he say that you disagree with?

I'll butt in. The AR-15 is based on the M-16, and it was *NOT* designed specifically to kill. It was designed specifically to wound, and that's the reason it uses a small slug instead of a much larger one like the AK-47 uses.

The whole theory was that if you could wound the enemy, it would tie up other enemy soldiers taking care of them, and so they wanted a projectile that could kill, but preferably one that would wound without killing.

Here's the difference between the US AR-15 (based on the M-16) and the Russian AK-47 rounds.

The AR-15 round was designed to wound as much as possible without killing, but of course if it hits a vital area, it will kill you.

That is not an AK47 round. It is a 7.62 X 54R which is nearly the same as the .308 Win ballistically.

Not sure where you got that view, but here is the actual size difference between 5.56x45mm vs 7.62x39 mm. The Russian round clearly has the bigger bullet, but as noted in their metric sizes (45 vs 39 mm case length) the American round is longer.

the one on the left is 5.56x 45

the one on the right is 7.62x54

one on right is not used in AK 47s.
