Funnily enough the earlier version of this kit DID have a metal barrel and turned brass ammunition, which I much prefer over the PE gun shield included in the "premium" kit.

I'm battling the old Tamiya Pak 40. It's a struggle.

What is the link to the model?

I love the dragon models but after 1 year the vinyl crap shit wheels just broke... Tip: Buy the Tamiya kit for 5 Euros additionally and just replace the shitty Dragon vinyl wheels with the 70s Tamiya wheels. Just have to cut the pointy wheel catch for the dragon wheels off and just glue the plastic wheels from Tamiya in place. And finito. There you have a pak that will last as long as you live. I hate these cheap ass vinyl wheels :) Grüße
