Not that I'm aware of, but it seems like in one thread the owner commented to contact him and he'd do something for you. I'm not sure if that still applies but it might be worth a shot. Rokslide member Gpatti is the owner of OV.
I just want to say I have both there Gators and bino harness and both are excellent in my opinion. I did have a little issue with shipment and OV was very quick to send replace in order. As twall said contact them and they will get you a code!
