I have a Remington 522 Viper that I bought off of a buddy and can't find any spare magazines for it. I have found some on GunBroker.com, but they want ~$50 ea for a 10rd mag. I'm torn if I should try and sell it outright, and use the funds to get something I'd rather have (10/22 or 597) or try and trade it in. Any suggestions?
