Yes, the 16 is from last year's batch where the hues on the uppers were a bit more olive(ish). The FDE 17 is from the most recent batch and is back to the classic brown hue. A friend of mine has a FDE SCAR 16 from the first batch of 100 that were produced for the US market (comes with the certificate and stuff) and when we compared my 17 with his 16 the uppers looked almost same color. I thought that was very interesting.Awesome family!
It's really neat seeing the different shades of FDE next to eachother.
