A fair number of people here saw my original FANG Nerf gun. I didn't have too many expectations for the project, but I was satisfied with the result even though it wasn't perfectly reliable in its last state. FANG 2 is a different method of achieving semi-automatic operation. This time I am using a rotating barrel assembly much like the Eclipse but simpler as mine only involves rotating barrels and not a belt or revolver magazine.
I'd like to get this gun right, so I'm using an evolutionary development process. Multiple prototypes will be made or at least revised and each new/revised prototype will improve on the previous. Prototype 1 is nearly complete and will be shown below. Prototype 1 uses a manually advanced turret for simplicity.
I could go on and explain in detail precisely what I did and my justifications, but I type too slow at the moment and have already said most of what has been done on my personal website. I'd suggest reading the following links:
The gun is obviously incomplete in the photo above. The structural piece holding the trigger valve and trigger is temporary and only serves to help figure out the correct geometry. A second structural piece to attach the turret seal piece to the tees above it is not made yet. There's no handle shown because it hasn't been made yet. And the most obvious omission is every barrel--as I mention in the links, the barrel lengths are to be determined with computer simulation.
The gun part is shown closer above.
This photo shows the intended ergonomics, which actually are pretty good as is considering the trigger angle is wrong and there's no handle.
