Space Marines Ultramarines Stalker Posted on July 20, 2015 by Rafal Maj The top gun is magnetized so you get both Stalker and Hunter guns for this tank. GW made it really easy to swap. I really like when they do this so simple. Click photos to enlarge. Posted in Warhammer 40k, Ultramarines, 40K Ultramarines Army and tagged Games Workshop, Painted, Ultramarines.
