Semi or fully automatic knex gun.

I know you people don't believe anything without pictures, but, I DON'T CARE!!! I have a video! I promise! Ok, this is a semi-automatic. Pull trigger, boom, pull trigger, boom. That is it, no pulling back the ram or anything. I have not made the fully automatic version, but all it needs is a motor on the trigger and it will be fully automatic!!!!!!

If any one wishes to post instructions on this gun, I hereby give you permission as long as you give me credit.

Watch the video here.

if u want a semi of fully automatic knex gun 1: you need the elastic band to stay in the gun 2: u need something to be pulled back by a motor or hand then for it to be shot forward by the elastic band which will hit the bullet 3: u need to make a magazine that will have bullets in it and so that the bullets can be pushed up over all its very hard plz tell me how u would make a magazine

Looks like you basically just said: In order to have a semi or fully automatic knex gun, 1- The band has to stay in the gun. 2- You need a pin. 3- You need a magazine. Then you asked something about how to make a magazine. This is a three year old thread. Not just that, this is a three year old thread that is about a design. Not a discussion of semi/full-auto designs in general. All I took from your comment is that you are some new member who was born in 1997.

What the hell happened to my formatting?

Easy build, but you only show the handle and trigger, only part of the barrel as well

I only show those three parts because that is all there is.

The white connector you see at the far right of the screen is the end of the barrel, so showing you the other half of the connector would be redundant.

Besides, you built it, so there is obviously no problem.
oh, ok then....I didnt realize it was all there was.... and yes, I built it, sorta. I had some other Ideas pop up in my head before i finished, so I took it apart...
What are you trying to say?
for this does the power come from when the trigger is relesed?

I don't understand what you mean... It is sort of like a double-action revolver. When you pull the trigger, the hammer (ram) is pulled back with it. And when the hammer is fully pulled back, it is released, propelling the bullet.
