Hey guys,
I know this thread is a few months old but having first hand experience, I thought id reply.
I own one of the Norinco ATds for years now. Ive used it mostly for squirrel hunting here in the swamps, I have used it to paddle my pirogue out of the swamps at 2am! Anyhow, I have put hundreds of rounds through it with no problems. Im not sure what you mean about the barrel shaking loose but Ive never experienced it.
The only problem I have had was breaking the extractor when I took it down, but that was because I didnt pull the bolts back slightly. My own fault. from what I can gather its hard to get Norinco parts now for some reason, and Im not sure if browning parts fit...
I would buy it, Dave
