There area few variants of the figure with him having gold, silver or black bullets on his leg. You don't see much interest in those variances, now, but they were something fun to differentiate the figure back in 2001.

And, with lots of army builders to now choose from the limitations of the mold are more evident. But, this figure is a reminder of a much different time in the Joe world when every month brought news of an upcoming release. Here's the best on this figure from around the web.
