if the gun was ever disassembled the selector could have been reassembled improperly leading to the gear/cam to be in the proper position on the receiver but the selector plate on the gearbox to not be in the right spot. This issue though has nothing to do with shipping conditions.

But the good thing to note is that unless the selector on the gun itself took a big impact to break a part (the selector plate on the gearbox is plastic) misalignment like that can't possibly happen by bumping it. It has to be reassembled improperly.

If it's just improper assembly it's just a matter of taking it apart and shifting the gears on the selector assembly into the right position, that's not that big of a deal, just rather dubious that the seller would not report that in the sale ad.

If the gun looks damaged... AKA.. big fucking hole or dent in the box and a big chunk of metal being bent, and you did not pay the 5$ for shipping insurance... well then... that's your own damn fault. :P

edit:

this is a gas gun? well then.. ignore my post and carry on. :P
