Bright blue is a rather common colour for polymer barrels. Why this is I have no idea. Maybe it's to differentiate them from their steel counterparts? Maybe to separate them from the occasional red one I've seen?

My Magneto is to die for. I portray him as the lonely god; he who sets upon his iron throne with troubled brow and broods upon the folly of man, both human and mutant.
