" In February 2006, we reported on the complex, decades-long campaign to find a new general-issue rifle to replace the aging M-16 -- and the two related weapon programs that showed promise. More than a year later, where are these guns? XM-25  This grenade launcher, which fires 25mm &amp;quot;air-bursting&amp;quot; shells that detonate in midair over targets&amp;#039; heads, is still being developed. But a larger, 30mm version of the XM-25&amp;#039;s microchip-embedded round will be shipped to the U.S. Navy by May, and is slated to be used in the new U.S. Marines Expeditionary Fighting Vehicle. SCAR  Gunmaker FNH expected its SCAR system, an assault rifle that&amp;#039;s more accurate than the M-16 and less prone to jamming, to be delivered to special operations units by late spring of 2006. It was an ambitious timetable, but at press time the SCAR had yet to be fielded, and FNH declined to comment. To engage an obstructed target, the XM-25 firer locks in the range of an intervening object with a rangefinder. An internal computer programs a grenade to explode once it has cleared the targets cover. (Illustration by Brian Basher) "^^<http://www.w3.org/2001/XMLSchema#string>
