Sure the GSG 522 looks great with the basic factory stock but if you want a more aggressive look or that classic MP5 look then you’ll want to switch out that factory stock. The good news about replacing your stock is that you can sell the factory stock on ebay for $20 which makes getting an after market stock even easier on the bank account (and with your wife). There are a few types available (when they’re in stock) and we’ll list them below.
