It is? The Worrblade Kit isn't better. It simply comes with more parts(i.e. hammer, bolt, double trigger). They are the same except for the extras it comes with.
If you have a stock gun, get the worrblade kit, but if you have already upgraded your hammer (which I'm pretty sure you havent) then just get the E-Blade.
