A modular fully automatic rifle designed by Shangpin to assist Chinese weapons, relying on the feedback data of the previous generation of firearms and the rich experience of the weapon group design team, giving full play to the advantages of Shangpin in detail design and modeling design.

We take the ancient Chinese fish intestine sword as the moral sustenance, and draw the inspiration curve from the belly of the sailfish as the feature of the gun body, which makes the sense of the gun body smoother. The improved adjustable buttstock is more suitable for people's facial curves, and the lines running through the gun body in the middle highlight the modern sense of the gun. At the same time, the unique gun body curve can be clearly distinguished from other firearms. The heat dissipation hole of the barrel handguard is an irregular rectangle, which enhances the speed of the whole gun.
