This gun is called Alley Oop which stands for All (ey) Out Of Porportion. It's not totally out of porportion, I just felt like naming a gun Alley Oop. The pilot valve is a ball valve. I don't really think it looks that good but it does work well. I decided to post it because no one else was posting anything too interesting (Want some grapes for example haha)

The piston is hot glue with some neoprene for a seal against the barrel.

And thus, from boredom, arrises greatness...or something. Looks good, and clean, better primming than my cannon. And with that said, I must build more.

The range depends on the projectile. Nerfs go fast but not far. Accuracy depends on how fast I can turn the ball valve without jerking the gun too much.

this is a coaxail. im guessing the C:B ratio is about .4:1 but other than that there is nothing wrong with the proportins :roll:

you would actualy might improve performance whith a shorter barrel
