     this gun disapointed me big time. this gun is not good at all. the pump sucks and isnt even attached to the gun. the trigger cannot reset itself automatically..... you can only have about 1 rubberband on the firing pin or else the grey connector of the pump will snap off..... very bad.

     Well you're right, this gun is pretty bad compared to guns nowadays.  The thing is that this was posted a year ago, so it was quite good for it's time.

    Why's this rated so low? This is a really good gun, one of your best.... Ehh, I have 2 questions before I start building this... 1. Ranges with 2-tied up rubberbands? 2. About how many yellow connectors does this use? (I'm starting to run out of those after building the DD-27, IAC's Duckgun on KI, the Dragonfly AST crossbow, and the Rising Sun...)

    /overexaggeration You reply to some or most of them, and they weren't directed toward you. Anywho, i think IaC posted a link on his orangeboard. Otherwise, ask him for a pic.

    You shouldn't place your comment bars into other ones. Now it is (I guess) impossible to see what you wrote in the middle one. Just mentioning, nothing personal.
