The M-16 has been on its way out for a while. As the GWII veteran said, it was the last nail for the coffin. Here are some good links about its
possible replacement, the OICW:
www.fas.org...
"Objective Individual Combat Weapon (OICW) will be a light weight weapon capable of firing kinetic energy projectiles and an air-bursting
fragmentation munition. It will allow soldiers to effectively attack targets at greater ranges, and to attack targets in defilade. It combines leading
edge technologies in miniaturized fuzing; integrated fire control; light weight, high strength materials; and munitions effects. OICW will increase
the lethality and survivability of the individual soldier. It is the sole lethality component of the Dismounted Battle Lab's 21st Century Land
Warrior (21 CLW) Top Level Demonstration."
