I wish I had pictures of my days in the military but they were very strict with pictures. In fact no cameras or even cell phones (since they can take pictures) were allowed. Also if caught taking pic of the internal of one of those rifles it would be court martial for sure.
But I will say that it had standard M16 parts kit, except the selector was a 4 position selector. It was safe, semi, burst, and auto. I played with the evil auto sear a bit since they never let us shoot it full auto just to see how it works...
Since at the time I had just experienced the Clinton era assault weapon ban, I thought to myself how it had "evil" flash suppressor and auto sears...
The thing has ZERO recoil... well it had some but it sure felt like shooting airsoft guns. This created problems because lots of Taiwanese shoots airsoft guns, and so some people did REALLY unsafe things with them thinking that the rifles couldn't possibly kill anyone. I kinda wished they made us train on T57 (basically M14) because that thing had lots of recoil, or at least I think so. My dad trained on them and had hearing problem because they never provided any hearing protection.
In retrospect I did do some details around what used to be a shooting range on the base, and actually found old bullets from T57's. The thing deformed very little and was mostly intact.
