That bushing is buggered , it also looks flarded at the back end , but could be the picture, link is bad, hood and slide don't look to bad to me, typical Nork.
I think timing is off and a bad bushing.
I sold one like it that worked great, or I could have sent you some pictures.
Norinco uses a different bushing in 9mm guns,if it was 45 , common as hell.
But if it is that loose, it should not bind the barrel, but if it is also that loose in the slide It could tip enough to lock the barrel, Maybe????
Delask should have bushing, they do lots of 1911 builds.
A P.S., long shot, but while you are looking , check the bolt face and brass to make sure it is not jamming up there.
