Sabre Defence Scores a Hit
Sunnen's HTB Tube Hone
If the United States' warfighters are to be believed, the .50-caliber machine gun barrels made by U.K.-based Sabre Defence Industries are the best in the business. Part of the reason for that preference, officials at Sabre's Nashville plant believe, is the superior accuracy and easy cleaning that result from the excellent bore geometry and surface finish imparted by a HTB tube hone from Sunnen Products Co. of St. Louis. Since installing the hone, test groups from sample barrels have tightened up nearly 100 percent over the Army's requirement.
