On October 31, 2005, the OICW I program was cancelled. The reason given for the cancellation was stated as: "This action has been taken in order for the Army to reevaluate its priorities for small caliber weapons, and to incorporate emerging requirements identified during

However, the weapon had serious problems: it did not meet weight or cost targets, and the 20 mm High Explosive Air Bursting (HEAB) did not seem to be lethal enough in testing. To compound matters, the kinetic-energy component had to be light and short in length. As a result, the

OICW Increment 3 was the XM29. The M203 was listed as being replaced by a combination of
Increments 2 and 3. The M249 was also to be partially replaced by a lightweight MG (LMGA, now LSAT), which was listed as being the successor to the

In the aftermath of the ACR program, the OICW program began. There were two main contenders, one design by AAI and its companies, and the other by ATK (with H&K and other companies); ATK and H&K won.

The central idea of the program was to develop a rifle that enabled the attacking of targets behind cover by using airburst munitions. The munitions were to be much smaller than pre-existing
