Fn civilian line is made in a seperate factory. The US mil rifles are made to the actual TDP where FN civilian line is reversed engineered and they would get sued by Colt if they did. US colt LE line is the closest to the TDP out there for US civilian sales. Up here colt Canada is the closest you can get if any rifle to the TDP.Another point, has anyone on here tried making a more up to date clone by using FN parts? Since they have been supplying the rifles since ~2013... That's where I'm heading with my clone.
