Well, to me the XM-25 makes more sense anyway. The original OICW may have been ok in concept, but I (and apparently others in higher places) had doubts about the lethality of the 20mm airbursting munitions, and the snubbie rifle (a mini G36, really) would have been worse than useless at anything other than point blank range. So if the rifle portion isn't worth using, why have it to begin with? Ditch it and increase the size of the HE munitions, which is the entire point of the weapon system to begin with.
