Mag o-ring replacement kit contents

[LoveMyMagMoreThanYou]

I know this is a noob question but I want to replace all of the orings in my mag. How many kits do I need? 1? 2? I feel stupid just asking, but the store just lists the rings and it doesn't say that it could be used in this way. Thanks.

One kit = 1 full gun.

Why would they make a kit if they didn't give you all the orings to fix everything? (I say that, but Dye does that for their DM4. They give you all the orings EXCEPT 1. How did we fix? An RT Parts kit. )

Thanks. I figured as much but the description just doesn't come out and say it and it was easier to post than to run down the parts list and match it to my owners manual or some other blow apart diagram. AO ROCKS!!!
