Hey Tfans, I recently picked up the new deluxe mold of Batleblade Bumblebee. Unscrewed the right arm blaster and noticed the holes are the same as Human Alliance BBs forearms (if you removed the seats). So (you guessed it) I installed them into HA BBs forearms and they fit! I never liked the seats on his arms and I'm not a fan of the human figures. I'll eventally pick up another one to have a matching set of dual blasters on my HA fig. TRU has a sale on now. Buy one get one 50% off. How can we go wrong?
