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. The SOG Vulcan is also formidable with a powerful strength of construction. There is nothing weak about the Vulcan. Take forinstance the patented Arc-Lock. Or, the full steel liners encased in glass reinforced Zytel handles. The blade is a full .155" thick with spear point shape. Most importantly is the new kick deployment of the blade. Press on the back of the blade and the knife comes out fast. Reversible clip, Arc-Lock, double thumb studs make for complete ambidextrous use.
