I have a slightly used Tango Down Vertical Grip in tan I'd like to trade for a black one. The one I have has the dual latch bars. I prefer the QD lever but beggars can't be choosers. I'll even throw in the little latch bar pins I made. They make it easier to attach the grip to the rail.

Would sell for $70 shipped, but I'd rather trade. Will post pics if necessary.
