Heckler & Koch has an MP5 and an MP7 in their new RAL-8000 Green-Brown color scheme. I first recall seeing a complete H&K rifle, including optics, in this color scheme when they unveiled the H&K G28 DMR last year. Since then we have seen H&K machine guns and now we have submachine guns in the same colors. Also note that the MP7 has a red dot sight in the same color scheme.
Here are some more H&K photos from the DSEi show …
The poor neglected H&K G36 does not get a new coat of paint. Still H&K matte black polymer.
