What about the standard 311 20" inch rifles? Ive also heard that the Chinese ARs use ALOT of MIM parts. Can you attest to that?

The 311 were very popular in the 90s when the Colt & Oly were the only US made options.. but more expensive as well.
Never owned a Norinco… I’ve heard/read that the 311 was not milspec since it was reverse engineered.. all threads were metric.
The newer M4 on the other hand is compatible with us parts.
Can’t comment on the MIM parts.. the 311 was known to have 6061 receivers.
No info are available on never models afaik.
They’re popular in Canada as well.. maybe some of your neighbors up north have more info
