In November 2013, Heckler & Koch applied for permission from the German Government to sell a new civilian-legal version of the G36. Called the HK243 in Europe and the HK293 in America, it is more similar to the G36 assault rifle than previous civilian models. The main difference is the bolt is redesigned to not allow a conversion to fully automatic fire. It has quad picatinny rails and accepts STANAG magazines. Four different barrel lengths from to and four stock models (short fixed, long fixed and two adjustable) will be offered.
