It solid, comes with extra hardware, looks sweet but I'm sure it weighs twice as much as the blaster With all the internals in it. It comes with key holes that will allow you to put real steal parts on if that's ur thing. very strong, you can be very aggressive with ur pumping with this kit that has Picatinny rails built in. Another reason for not 5 starts is the Black kit looks a little to much like real assault weapon, but that what orange barrels are for.
