    very good design and i see how it would work, it is actually a very smart idea for a mechanism. if i built this gun i might be able to mod it into a working semi automatic gun. but unfortanately, i don't have much free time on my hands. so, sorry i could not help but this is really a very smart idea.

    First of all, that is not semi-auto. Anyways, I think you need to beef up the trigger. It seems pretty flimsy.

    No it doesn't. just look at the picture. You pull the pin back and hook it onto the green rod in the back. The trigger hits the red connector on the pin and releases it.

    he wrote this in the intro: Here's a Knex gun that doesn't work and i wanted to see if anyone could mod it. if it doesn't work, its most likely not semi auto. its a pin mechanism - not semi auto - anyway.

    how is this not semi auto? and i usually place my thumb on the 2 yellow connecters holding the handle in sort- of place btw P.S.: first comment!!!
