GI Joe Sigma 6 is a line of GI Joe action figures that were produced by Hasbro from 2005 to 2007. The GI Joe Sigma 6 action figures stand at approximately 8 inches and have more articulation than the 3 ¾-inch GI Joes. Because of the short run of these figures, they are highly sought after. At Yo Joe action figures you can find great deals on all of the GI Joe Sigma 6 toys.
