Perhaps the most innovative small arm of recent years is the XM-25 "Punisher" 25-mm grenade launcher. A laser measures the range to the target, so the grenade can be set to explode midair at the exact point it passes over a foxhole or a wall to target enemies behind cover. Five weapons were issued in Afghanistan on a trial basis in 2010 and they have had good reports. However, the XM25's estimated cost of over $30,000 may prove to be something of a limitation for now.I've got to scream Bullshit! That thing isn't important. While nice, while interesting, it certainly doesn't have the cachet, the history, the excellence of the Colt Peacemaker, or the 1911 as designed by the sainted John Moses Browning (PBUH). It certainly doesn't show design excellence, or elegance like a Maxim or innovative design like the AK47.
Popular Mechanics is a great magazine, but they're off the mark including this prototype in their list.
