FedEx is notorious for damaging shipments.
My oldest brother recieved a driveshaft for a 275GTB Ferrari and it was literally smashed in the middle. They must have run it over with a truck or forklift!
Once I shipped a motorcycle engine and the dropped it, smashing the crate. The ship to address was obliterated and they just kept it at their terminal not knowing what to do.
I am always wary of using FedEx for guns, but really, they are the most convenient...
