Is Skif's D-30 kit a fiddly build, or does it come together nicely? I haven't seen any construction reviews of the kit so I'm a little apprehensive about buying it. Also, for those of you that know, can an is-2 aluminum barrel be used to replace the plastic one? I doubt they're the same barrel, but I sure wouldn't know that. Thanks in advance

do you mean the 2S1 Gvodzika barrel? if so, look at these two pictures, the 2s1 has a bore evacuator, whereas the D30 doesn't, it also has a larger, double baffled muzzle break

or if you meant the IS-2 Heavy tank.. then, here's a pic
