where is Ratchets automorph gun? it's said on the back of the box he has it. does anyone know where it is?

It does?

Near as I can tell, it was a very early idea/concept/prototype thing that ultimately was dropped. I imagine something similar happened with Starscream. Note how HIS toy box has the callout "Missile Launchers Attach to Arms!" instead of "Arms Fire Missiles!"

It's what they call the roof rack/stretcher when it's attached to Ratchet's arm.

I noticed that Ratchet's axe is the perfect size for the barrel from Protoform Prime's gun. I plan on getting another Prime, and taking the light blue barrel from his blaster and somehow affixing it to Ratchet's axe so that it is removable in vehicle mode and non-battle robot mode. It's roughly the right size by the look of it...though I really should check with my actual figure before I go and order one only to have it not work.

Somebody NEEDS to make a gun to replace his axe gimmick. He didnt even have AN AXE in the movie, he had a saw! And he used his gun more than the saw in the 1st place..
