One of the coolest accessories you can get for your GSG 5/522 is the big 110 round drum magazine. It holds 5 times what the single 22 round magazine can hold so you can go out shooting targets or varmints with this magazine alone and never reload or just reload a couple times for 220 rounds…sounds like a blast.
November 2013 and it’s in stock ! >
The GSG 522 rotary magazine prices range from $89 – $100 however it’s very hard to find one right now in mid 2013…they’re sold out at most places.
They fit on any of the GSG 522 22lrs and hold a max of 110 rounds.
