I am pretty darned colorblind, so bear with me.
I like this color for my next AR:
Now that color is tan, which we will call VLTOR tan.
This brings us to tango down, who offer their vert grip in a tan color as well:
Magpul, on the other hand has what they call olive drab (top) and coyote brown (bottom):
neither of which are tan, yet they offer the seemeinlgy perfect tan color on magpul stocks but only the severely used marine ones....
Magpul does not offer rails in the tan color - that is my point.
So, the only company that produces non-buttstock accesories in tan would be tango down?
