It is the same length air tube as the Scorpion SE but that rifle also has another few inches of air capacity between the gauge and firing valve, on the Gold star this area is occupied by the reg so any air in there is at regulated pressure resulting in a slightly lower reservoir volume. The GS still does more shots from this lower volume though.
I have fitted the original scorpion air res on my GS now which is 3" longer but to make the gun heavier and move the balance forward rather than to add to the shot count.
HFT, for people with only 2 buttucks!
