This is a hard one. You might think this is a normal M16, but it is not a normal M16. There are features on this gun that shows what gun it is. View attachment 46338
Since no one seems to know this rifle, I'll give the answer. It's an SP-1, the civilian version of the M16. If you look at the lower receiver, you wouldn't see the details of the lower like on other AR-15 rifles
