FILE - In this June 25, 2010, file photo Britain's Prince Harry fires a Colt M4 assault riffle on a United States Military Academy range in West Point, N.Y.  The Defense Department is searching for the successor to the M4 combat rifle and gun makers are loading with lobbyists to win the work. Colt Defense of West Hartford, Conn., had an exclusive deal to provide M4s to the U.S. military and didnt need a hired gun looking out for its interests in Washington.
