Sabre Defence of Nashville, Tenn., is producing more accurate and easier to clean 50-caliber machine gun barrels that significantly exceed U.S. Army specifications. The secret, officials relate, is keyed to improved gun bore geometry and tube hone.
The British-based company took over the Nashville plant in 2002. A spokesman noted that 50-caliber gun barrel demand has grown from 100 to 1,200 units a month. Workers there fabricate both ground based and lighter aircraft barrels.
