hi people just wondering if any one can tell me the inside diameter of the adaptor and the depth, that would be how far it does on the barrel, and it would be a bonus if any one knows the outside diameter of the air arms s4** barrel chears people

The S400 barrel is nominally 12mm diameter with the last 36mm of it turned down to 9.97mm diameter.
