at one time norinco was making a1s --the were horrible--some of their parts actually made it into the US back in the late 80s --early 90s before the clinton ban --their bolt carriers were not hard chromed on the inside and they were made from the wrong steel. worst looking lowers i ever saw produced too --looked worse that olympic and DPMS back in their cast days--IIRC --though i have slept and been few a few wars since then.
i suspect the do make copies of the current m-16a2s and m4s today. and that thir greatly improved from china's past attempts.
the m-16 is produced by several friendly countries as well ==the PI made ones seemed as good as any of the early a1 types to me.
