I have a Brand New (still in the package) Custom Products (CP) Flame Drop forward. It is black in color and it is the 2 inch drop version. It will work with any rail mounted air system (arm, apoc, conquest, etc.). I was given this from a sponsor a while back, but I don't own a rail mounted air system, so I have no use for this drop forward.
Price: $25 shipped to your door (U.S. only)
E-mail me if you are interested.
Here is a pic (mine is exactly like the one pictured, except it is black in color).
