Umarex De earth g36 parts query + paint info

[millest]

hi folks

apologies if this is in the wrong place, if so mods please move, but this seemed more appropriate. I have recently purchased a nice new beastie of a G36kv in Dark earth but have found the top rail with inbuilt sight a bit of a pain in cqb. the question in short does anyone know if there is either a g36c style rail or a flat top rail with no sights availible in dark earth anywhere? if there is could you let me know

failing that does anyone know what a good match of paint is for Dark Earth?

cheers

millest
