Kevin,
The OICW project was cancelled October 31 2005!
The whole set-up was just too heavy and bulky!
It weighed just 5.5-kilo's empty and 7.0-kilo's loaded!
The airburst munition was found not to be as lethal as thought it would be!
Cost wise it was said to make a solidier so expensive to field that he couldn't be risked in combat!

Star-Wars tech may look fine when playing at the range but in combat you cannot risk your lives on toys!

Just as you clamor for the M-62(damn fine weapon!)the best weapons for our troops need to be reliable and cost effective!
Mike
