Yes, M22s were in Vietnam. Chinese sources are very proud of the hooded sight, it was one of the key "indigenous" features incorprated when they type-classified the Type 56. If you see a milled Type 56 with an open sight it's because it is using Russian barrel parts.Brick said:Well I did miss that milled open hood on the thread. I see it now. That is why I am hoping for more pics as that is only one I have seen with an open hood. Just trying to make sense of it. Also trying to figure out what was the most common for Vietnam era capture 47's. I haven't been able to find any good pics of capture guns markings. Were there any M-22 in Vietnam? If not, what era is it from? This is the info I am trying to nail down.
