Just got my Generation Toys Tyrant not-Megatron model kit from BBTS, tore my fingers up putting him together but he is a pretty great little Megatron. There's one thing I don't get however. It seems the Scope parts that latch onto his back in robot mode don't actually connect? The just sort of slide in but there's nothing actually holding them together, not even friction. There are square-shaped recesses in both parts that LOOK as something is meant to plug into it and hold things together, but the instructions don't show anything like that and there's nothing on the sprues Am I missing something here?
