ATI GSGGERGGSG1622S: The GSG-16 22lr Rifle is a light weight, tactical style rifle based off of the classic GSG 22 caliber rifle operating system. The GSG-16 features a newly designed collapsible stock that also serves as an additional magazine storage compartment for either high or low capacity magazines. The re-designed forend features standard picatinny rails mounted onto an M-Lok style hand guard. The cocking tube assembly features an ambidextrous charging handle so you can switch up charging rounds to meet your comfort style. The redesigned front and rear sight have been simplified and streamlined to give the shooter faster target acquisition over previous GSG models.
