No probs understood, by fill rig I meant the brass adaptor that goes between the cylinder and the hose from the dive tank. Are you looking at a direct trade?Here is a link to the Air Arms catalogue, if you download the PDF document in the lower right corner the front cover of that document shows a very similar rifle. The difference is that mine does not have the diopter site and is fitted with a silencer and a large telescopic sight. It also comes with a gun bag. There is no filling pump though as I used to get the cylinder filled via a dive tank. There are some other bits but until I check exactly what is with the rifle I would rather wait and check than guess and give you the wrong information.
