To my knowledge, it's the most compact tubular magazine gun to date. These are the instructions to build and fire it.
To entice you to build, Insight also:
Can hold up to five bullets at a time.
Gets about 25 feet; this is very good for a pistol of this size.
Uses a red rod sized firing pin.
Has a comfortable handle.
Requires no cut pieces. (Nor do any of my posted guns, come to think of it.)
Shoots green rods. (A downside for some, but a pro for others).
And... Yes, the gun has a theme song: Insight by Joy Division.
Step 1: Build All the Things
Also of importance, those bands do not have to be cut and tied together; it would actually be better if you left them intact; I just ran out of full looped bands, sadly.
Step 2: The Internals: Part One
If you have any questions, please send me a comment explaining your troubles. I'll be happy to help.
Step 3: The Internals: Part Two
Please leave a comment with your concerns if you need help.
Step 4: Encasing the Internals
Step 5: Putting on the Bands
Again, comment if you have a problem. I definitely
Step 6: How to Load and Fire
If you've come this far and have built this, I hope that you enjoy the gun!
(If it's not working, see the next step.)
Step 7: What to Do If It's Not Working
If your trigger is not working you can do one of two things:
1. Put less rubber bands on the firing pin.
2. Get a hot glue gun and glue the one piece of the trigger together. A note will be placed to show where you should glue if you want maximum power.
