该枪由SG550标准型步枪衍生而来,保留了机匣顶部固定的转鼓式照门机构,并在其前方加装了一段皮卡汀尼导轨,用于安装光学瞄准镜。由于照门太高,直接在机匣顶部的皮卡汀尼导轨上安装瞄准会造成瞄准镜目镜与照门碰撞,因此机匣顶部的皮卡汀尼导轨上又重叠加装了一条皮卡汀尼导轨,用来安装瞄准镜。这样瞄准基线高度随之增加,故在枪托上加装贴腮板,以达到舒适的瞄准姿势,该枪针对民用市场而设计,因此只能半自动发射,其发射5.56×45mm
Derived from the SG550 standard rifle, the gun retains the fixed drum-based door-release mechanism on the top of the casing and has a Picatinny rail in front of it for optical sighting. As the door too high, directly on the top of the Picatinny railframe installation aiming will cause the aiming mirror eyepiece and according to the door collision, so the top of the casing Picatinny rail and superimposed on the installation of a Picatinny rail, Used to install sight. This aiming at the baseline height increases, it is mounted on the butt plate affixed to achieve a comfortable aiming position, the gun designed for the civilian market, it can only semi-automatic launch, which fired 5.56 × 45mm
