So I drop off my RIA 2011 Full Rail Gun at FedEx today sending it Arnel at Armscor to have him up grade a bunch of stuff and that is the response I got at the front desk at FedEx.
They had to check their little 3x4 official FedEx card to figure out what to do with my gun.
I brought the gun to FedEx in the original plastic case and a box of parts. The girl behind the counter said that she could not pack the gun for me

But she did pick up the case to see what size box I needed. She called every person in the place to ask what she should do with my shipment and of course everyone had their opinion. But in the end she default to the 3x4 FedEx procedure card.
It end up costing me $120 but it will be well worth it when I get the gun back from Arnel.
