Opmod diamondback scope fde - Vortex OPMOD Diamondback Tactical 4-16x44mm Rifle Scope, 30mm Tube, First Focal Plane (FFP)

I own several vortex scopes and this scope is typical vortex quality. The only complaint I have is that the fde color is not even close to the fde colored parts that are installed on my ar10. I purchased the vortex OPMOD sport cantilever 30mm mount fde at the same time and the mount matches all my other fde parts perfectly. and don't understand why the scope is so for off in color sinch they are both produced by vortex. I contacted Optics Planet about the situation and all I was told that the custom colors are not guaranteed to match. I feel like that answer wascopes not acceptable, if they can't gaurantee the colors to match they shouldn't sell them. Very disappointed with the explanation.
