Arnold Schwarzenegger has fired a lot of weapons in a lot of action movies, from The Terminator's Uzi 9mm to an antique Vickers machine gun in The Last Stand. However, the biggest, baddest and most ridiculous firearm that the Austrian Oak has wielded in his entire career is without a doubt Eraser's EM-1. The science behind the weapon is questionable to say the least, what with the scope being able to see through solid walls and human tissue as well as the ability to fire aluminum rounds at the speed of light. That being said, nobody goes to a Schwarzenegger flick to for the realism and Arnie takes things one step further by wielding two of these bad boys and destroying everything in his path.
