Yep...same problem. The right arm does not sit in tight making it droop about 2 or 3mm causing the spear to look slightly bent. This does not bother me at all because for one both arms are covered by the cloth he has on where the arms are attached and two...the bend is so slight it is something I would have to point out for anyone to notice.
I really love this piece it looks awesome next to the Ex. Undying Carcass.
