The issue with Century assembled FAL's is their use of parts bins with zero QC(just like the thousands of Lee-Enfields they assembled that had bad headspace.). Century FAL's are known for being assembled with a mixture of 'inch' and 'metric' parts that came out of said parts bins. That was the cause of a lot of the feeding issues. The parts didn't fit. Nobody can tell the difference from a picture.
Personally, I would not touch any firearm Century had anything to do with.
"...US BATF deemed made the rifle a..." They decided, without benefit of legislation, that "Once an MG, always an MG'. Then they exported that nonsense.
