Here is a good site. The troops are all for it. They think the pictured model will be issued with the Rifle. Plus's and minus's to everything, of course. Both the M-16 and the M-4 use the .223 bullet.

However, a big draw back of the 5.56 round is poor penetration and poor long-range effectiveness compared to the 7.62 NATO.

The .223 bullet can travel 3,200 feet per second and it produces minimum recoil. The maximum penetration occurs at 200 meters. At ranges less then 25 meters, penetration is greatly reduced. At 10 meters, penetration by the M4 round is poor, due to the tremendous stress placed on this high-speed round, which causes it to yaw upon striking a target. Stress causes the projectile to break up, and the resulting fragments are often too small to penetrate.
