Description

These BCGs have a very minor cosmetic blem in the finish which does NOT affect performance or warranty in any way whatsoever.  The finish is still nitride, but looks almost like DLC or a black nickel boron finish.  It has the same properties and specs as normal nitride BCGs, but may look slightly different in color than other ones.
