The look of this marker is very good and it easy to clean. You are just to upgrade the barrel and add an expansion chamber for this gun as well. I never have a ball jam or break in my barrel. And all extern parts are spyder standard.
Find some piece now (2001) is not easy when you have a mechanical problem.
The barrel and add an expansion chamber is necessary. I never jam or break a ball in the barrel whit this gun. But the mechanical piece is not easy to find. For me this gun is better than the spyder series when you upgrade this marker.
