While taking a break from the Pakwagen and working on some figures, I picked up Dragon's Tiger. A real great kit and fun to build too. I was working on the gun assembly, here are some pics and info as I found the instructions a little confusing. There are three options which involve a choice of plastic or metal barrels. I chose the metal barrel. There are also several optional gun mantlets. The first step was to glue the gun tube, A20, to the mantlet. Parts C19 and 25 were then glue to the mantlet and the machine gun, C27, was installed. So far, so good. It gets a little confusing when it comes to adding the breach to the barrel. Here's how I did it. The barrel is slipped in through the gun tube. There is a groove at the end of the barrel, this is where a retainer, A9, attaches, as seen below. The instructions did not quite make this clear, it looks like it glues between pieces A4 and A23, but it has to go on the barrel first like in the pic.
