We ship a bunch of packages by all the carriers. The big difference between Fed Ex & UPS is their conveyor systems. All the packages are off loaded onto a main belt with the shipping label up. They pass thru a scanner & when the package scans at the appropriate side belt, it is diverted onto that belt & it's loaded into the correct truck. The difference is that when the package is diverted in UPS, it makes a 3-4 ft drop. Fed Ex has no drops.
This is somewhat true, however at the UPS Sort Center that my company maintains any package over 36" in length or 40 lbs. is THROWN onto a drop chute and falls 36" to the floor, unless there is a sort cart under it, then it only falls 24" for the hand sorting to begin. If it's going out for delivery local it's thrown on the local sort belt by hand to be loaded in the little brown truck, if it's going anywhere else in the world via ground it's thown in a long haul for a trip to Syracuse to go through another tossing around and abuse.
FedEx's local Sort Center uses us also for it's conveyor maintance, with the equipment almost the same less the paint color, drops to the floor from the end of a chute is 36" unless a human is there to catch the package to load into a long haul truck, local packages make the truck without a drop to the floor, but it's the trip there that gets you.
I've never worked on any USPS equipment in a Post Office Sort Center as they have there own and don't out sorce, I've seen it at auctions, and in a scrap yard, the package belts looks like any other conveyor system I've ever maintained and not sure how you would change elevation on one with out the package going down a chute with a drop. Any firearm in a full stock configeration is going to be to long to fit through any USPS mail automatic system and will be hand sorted.

Imagine the above system in the link X 50, that's 16 in doors and 34 out doors at UPS, not counting the ones the local trucks use.
Every day a couple of hundred pounds of remnants from the 19 miles of belt that is in the local sort center is collected and shipped to Memphis to be figured out "Who does it belong to?"
I like USPS myself, even though the other guys pay me.
