Well, seeing the positive response I got from the slideshow and requests, I thought I may as well post it. If you can build this thing, you will be rewarded with a very fun pistol.
Step 1: The Body, Internal Barrel, and Part of the Mech
This is the overall receiver/body of the pistol. Should be easy to make.
Step 2: The Handle, Mech II, and Other Stuff
Step 4: Turret Stuff and Other Last Minute Stuff.
Step 5: You Are Done!
You have just made the OodaVolver! Have fun with it!
If you make this gun, show me a pic of yours and I will add it to the instructable.
