Small Scale Military Headquarters

I just purchased the fov 1/32 grant action series at target. The 37mm gun in the turret will not point level, it is always pointing up. I took the tank apart but can no figure out how to fix this.
any help would be great

NH, I have no problem with mine. It may be hard to find the exact spot but my guess is there is some plastic flashing that needs to be trimmed.

That is exctly what I did.
thanks
