As of this moment, Numrich has magazines for the Remington 522 Viper

.

I already put my order in for two of them; my guess is that they will sell out quickly. These are the steel-body magazines; some folks attribute many of the problems with the 522 Viper to when Remington switched to the plastic magazines. If you have a Viper that has feeding problems but is otherwise functional, consider trying one of these.
