This lightweight .22LR calibre rifle is based off of the classic GSG-22 calibre rifle operating system. The GSG-16 features several enhancements to give it a modern look. The GSG-16 features a newly-designed collapsable stock that also serves as an additional magazine storage compartment. The re-designed forend features standard picatinny rails mounted onto a M-LOK style hand guard. The cocking tube assembly features an ambidextrous charging handle. The redesigned front and rear sight have been simplified and streamlined to give the shooter faster target acquisition over previous GSG models.
