Veteran .25 magazines question...

Can someone tell me if their Veteran .25 magazines have 1 or 2 O-rings/bands around them?

I got one magazine that has two orings, and one that only has one. The one with only one oring doesn't really feed right, the pellet probe gets caught up on the oring.

I had never used the one with a single oring before, so it didn't break off or snap or anything.
