I had the same problem. Norinco’s are a mishmash of English and metric screws . The screw you are talking about is 4-48 on mine. I made my own. The other problem is that the left and right are different. Also the way they work is that they left scre tends to tighten and the right tends to loosen
Thanks for the information man. I really do appreciate the thread size you came up with! Nice!!
