Having issues disassembling Metal Gear Rex

[Hibiki]

I'm having a hell of a time removing the rail gun from the arm. Any advice?

I only disassembled mine a few weeks back and the rail gun is a ----- to take off. You have to be careful not to force it coz it feels like it well break. My best advice is hold it right by the part that connects to the rail gun and wiggle it off.
Good luck
