Dwayne Johnson Wields a BFG in Prepartion for G.I. Joe 2

Dwayne “The Rock” Johnson has tweeted a new image of himself wielding a badass looking M249 SAW light machine gun, one of those guns that if I were holding it, would practically dwarf me, but in the Rock’s hands, it looks practically tiny. Dude is HUGE.

Johnson captions the pic with: “Found my gun today! M249 SAW. Guess who/what I envision in my crosshairs?”

Um, Cobra?

Johnson is no doubt getting in shape, LMG and all, for his role as Roadblock in Jon Chu’s upcoming “G.I. Joe: Retaliation”, due out sometime in 2012. The film will also star Channing Tatum, Adrianne Palicki, Ray Park, Byung-hun Lee, Elodie Yung, D.J. Cotrona, Ray Stevenson, and Joseph Mazzello.
