Question regarding gas mags.

[W.I.L.F]

First of all, I apologise if this is in the wrong section. I thought about posting this in the "Technical Help" section, but decided that the question at hand wasn't massively technical.

Anyway, on to the question:

As I'm aware, if you store gas magazines without any gas in them, the O rings will dry up, causing a leak. If this is the case, then why don't the O rings dry up during the journey from the factory to the shop, or during their time being stored in a shop's warehouse?

because they are greased, keeps them supple, when you start using gas in them, the grease comes off, gas has lube in it, keeps them...lubed, no gas, they go dry
