Hi Mo, I have been trying to see where and how you are short of guns. I see that you have put 13 ports on each side ,I only put in 12 and the very last ports on the stern cabin I leave closed but there is a gun in there although a smaller weapon than supplied but you can only see it when the lights are on. That accounts for 4 but you would still be short . They must have packed it wrong mate. The pin rails look like they wont give you any trouble and as for glueing them in depends on how tight a fit you have got. Looking tidy though.
