i have 9 studs which fit into the cases to fit the barrles onto. 2 are stepped to a smaller size 6 are all the same and the 9th is the same diameter as the 6 studs but longer. looking at the diagram i have the 2 stepped studs fit on either side at the front, the 6 the same fit around the back, but the single hole in the middle at the front is far shallower than all the others and the longer stud i have left is not an obvious fit, diameter is fine but it only goes in half its threaded lengh. what have i done wrong this time?
