The Kinetic Rifle V.1

Here it is: the bullpup, tube mag, bolt-action, pump-action, sling semi-repeater.  This is by far my most favorite gun I have ever built.  

The reason I call it a "semi-repeater" is because while it has a magazine, loading it involves a two-step process of pulling back the rubber band and then pulling the pump.  Therefore you don't have to load each individual bullet into the barrel by hand, the pump does that for you, but the band still has to be pulled back manually.  The gun was originally intended to have the pump bull back the band as well, but to do so the pullback distance would have to be greater, requiring a larger barrel to house a longer pullback, requiring pieces I just don't have.  When I get the pieces I am going to make the pump pull the band back, and I will post that as the V.2.

What I love about this gun is that it takes many concepts and combines them to work in sync with one another.  I also like the fact that there is almost no limit to how powerful you can make this gun, since the ratchet can hold an incredible amount of tension. 

Overall it is an incredible gun, averaging ~60ft with the 1 band used in the video.  Though it isn't the most reasonable choice for a war (it only holds 4 shots in the mag and is huge), it is well on its way to becoming the most efficient knex repeater out there.

You probably get this a lot, but do you have an estimation to when it'll be done?

I will try my best to have it up this Sunday. You have my word.
Okay, I believe you. Haha

Here's an idea if you want to improve the concept. Make a gun three layered on the bottom (though with a 5 layer top for strength) and have a 5 layer pump that goes around the magazine to pull the bands back. Then have a normal vertical magazine. Use a sliding block device over the magazine so bullets don't load until you cock the gun which would push the device back and let the bullet load.
Then you could have a true pump action gun with a far higher capacity magazine. While I recall seeing one, it had a vertical magazine and overall the design just didn't appeal to me.
And actually, if you want, keep the horizontal magazine but extend it into the front of the gun instead of the back. Then you could extend it as need be and hide it inside where the pump goes around for style. And then you could also make an elevator device for the magazine if you wanted, though a sliding blocker would probably easier.

I have had somewhat of the same idea before, but my main focus right now is perfecting the utilization of the H-mag, and the only way to use that in this design would be to put it in the stock, since a pump wouldn't be able to slide around it. This is kind of the problem I ran into with my first shotgun design, the one that was going to use your ram design.
