About: Hi. I've sold off about 99% of my k'nex, but I still come here to check in on instructables, every 2 weeks or so. I like seeing what's new in the k'nex, and also other sections. I may or may not post my K'n...

    I got mine in something called a Starburst Spinner set a long while back =D And your opinion on the gun?


    Pretty nice but i like Seleziona's double blue rod shooting guns better. They just look better but yours has a pin guide and Seleziona's comperly sized gun does not. Now post the reverse crossbow NOW!!
