Introduction: Failed Knex Gun Concept - CQB Assault Rifle

I normally don't make concept guns, but I decided to see if this one mech I thought up would work. It works by having a ratcheted elastic powering a rotating firing pin. It all worked out on paper, but when actual building came around; this gun failed to shoot. But I was satisfied that the mech was possible, and functioned at all. I did take pics of the "completed" gun for you all to see. 



This gun on paper would have shot 25ft at about 300-500 rpm at an estimate. 


Now for the pics of the gun below.

I just finished up with my full auto smg that is gunna run off a drill. Its been a prototype for a few months and Its gunna be awesome. Even though it only has a range of 25-30 feet. It shoots oodammo which makes the range quite decent.

Cool gun man. Kind of based off of Oblivitus's concept? I made something a few months back that is kind of similar. I'll see if i can dig it out.

Have you figured out which part causes it to fail to shoot? I think that you could get at least a little more power out of the mech if you used a drum instead of a raw axle; two circles with 8 white rods connecting them would give the bands MUCH more power to actually move it.
