The General Electric M61A1 Vulcan is a 6-barrel 20mm cannon of the gatling-type. It fires standard M50 ammunition at 6,000 rounds per minute and is integral part of the armament of modern fighters such as the F-15, F-18 and of course the F-16. This Vulcan is also formidable with a powerful strength of construction. There is nothing weak about the Vulcan. Take for instance SOG's patented Arc-Lock. Or, the full steel liners encased in glass reinforced nylon (GRN) handles. The blade is a full .125"
