We're a small gun shop that is specializing in GSG products. We currently have all three available stocks for the GSG 522. We have the 110 rd drum magazine, 22 round drum mag and the 10 round drum magazine. We carry two different red dot sights that work perfectly for the 522 also. We have the hard to get Glock 42 magazines in standard and extended pinky grip as well as several popular holsters and after market sights. We are very fast on shipping out orders and if you place an order before 4pm CST then there is a 95% chance it will go out the same day.
