Yeah I know what you mean. Actually the 'piledriver' mode was a happy consequence of the design I didn't intend for them to be mounted in that manner. That being said, it's fully possible for the barrels to be pushed down and the piledriver end extend, but we have to keep in mind they are so small...Also, the 2 guns are supposed to sit into each other in alt mode, so having them in single pieces is preferred. I'm also worried about paint rub issues that arise with sliding parts. I like your thinking though. When I receive the test prints I'll see exactly how small the guns are and maybe changes can be made?
