Nothing wrong with the Revell kit, but I've heard that the gun barrel on the A4 model (number 03103) is inaccurate, it's made according to a prototype, which had a 105mm cannon, while the production models have 120mm cannons. Of course I could get the A6 kit to donor an accurate cannon, but with same the price I could buy the new dragon kit.

The only fault with the A4 kit barrel is that it's too thin beyond the thermal shroud (the bulged part in the middle). Thickening it is out of question, same with making a completely new barrel. But could the front section be scratch-built without too much trouble? Cutting off the barrel beyond the thermal shroud correctly would be difficult though, not to talk about gluing on the new scratch-built section, straight.

But what about aftermarket? Are there any replacement barrels available for this kit?
