When U.S. soldiers need to penetrate a tank's armor from a mile away, they count on a weapon that evolved from the garage tinkering of a former wedding photographer.
The .50-caliber rifle created by Ronnie Barrett and sold by his company, Barrett Firearms Manufacturing Inc., is the most powerful firearm civilians can buy. It weighs about 30 pounds and can hit targets up to 2,000 yards away with armor-piercing bullets.
That kind of power has drawn a customer base of gun enthusiasts, Hollywood actors and Barrett's most loyal buyer, the U.S. military, which has been buying Barrett's rifles since the 1980s and using them in combat from the 1991 Gulf War to the present.
But the powerful gun has drawn plenty of critics, who say the rifle could be used by terrorists to bring down commercial airliners or penetrate rail cars and storage plants holding hazardous materials.
