Step 6: Your Finished!

Your probably wondering why I called this gun a pistol/shotgun.
Well, I did it because if you pull the ram back once, it will fire 1 orange connector, if you pull it back twice, it will fire 2 and if you pull it back 3 times it will fire a maximum of 3 orange connectors.
So, its sort of a shotgun!.
I hope you have fun with this gun!

    Terrible design. In addition to what Killer~safecracker said, putting the mag behind the trigger makes it much worse.

    I agree up to a point, if you load 3 bullets in to it its as if the trigger is where the magazine is.
    Anyway, i will improve the trigger design on my next gun.


    This is pretty good, especially for a first posted gun =D 4.5*

    Never never never never never put a trigger that far forward! There are lots of ways to get a trigger farther back than that. Anytime you have the bullet before the trigger you loose a ton of power. Add the trigger placement like that you're lucky to get 10 feet.
