Interesting.It's very light. Most of it is polymer
It's cool and all, being what it is and the rarity of having a Chinese military rifle. It felt cheap. It is mostly polymer similar to the UMP and MP7. I don't recall what caliber it shoots but it's a proprietary round. Believe it or not, this rifle is privately owned and he brought it in looking for a sling set up as close as the Chinese one as he could get. He built it on parts smuggled out of and imported from China. The length of pull on it is really short and any normal sized person will have a little bit of trouble shouldering it comfortably. The gentleman that brought it in was Chinese too. We joked a bit after he left about being a Chinese spy. To my knowledge, the u.s doesn't have one in it's possession. I know a guy that trained foreign troops and got medically discharged a couple years ago. And he was saying he didn't think the u.s had one to examine. Complete unicorn rifle.
