This Is My Knex Shell Ejection Gun.
It Uses The "TheDunkis" Mechanism For The Shell Ejection. Its A Pretty Simple Gun, However It Has A Basic Trigger. I Posted These Instructions 'Cause I Couldn't Find Any Clear Instructions And Because Of That I Took Me Some Time To Get The Mechanism Figured Out. It's Very Accurate ('Cause It Uses Those Shells).
Unfortunately You Have To Cut Two Pieces, I Don't Like That. But You Really Have To. Those Black Ball Sockets Look Similar To The Grey Connectors You Have To Cut, But They Won't Work.

Parts List:

Green Rods: 25
White Rods: 9
Blue Rods: 7
Yellow Rods: 3
Red Rods: 1
Gray Rods: 4

- Gray Connectors: 26
- Orange Connectors: 16
- Yellow Connectors: 11
- Snow Flakes / White Connectors (8 Teeth): 9
- Small Blue Connectors (Smaller Than Single Teeth Gray): 4
- Black Connector: 5

- Blue Spacers: 4
- Gray Spacers (To Make 4 Shells): 12
- Rubber Bands: 3
- Cutten Gray Connectors (Single Tooth, Picture 4): 2

    this gun dodnt work ram dodnt go through conecters

    I've already made another shell ejection gun (same mechanism) but a bigger one. But i'm not gonna post any instructions 'cause its a large gun. I'll post a slideshow and video soon (up to 2 weeks).

    'Cause you can't use "Black Ball Sockets" (there's a little difference between them): http://knex.com/product_image.php?imageid=70   These are little curved to hold the "Black Ball Joint" (http://knex.com/product_image.php?imageid=69) , the cut gray connectors aren't curved. Unfortunately there's no other way to get this working.

    These cut gray connectors avoid the blue rods, when they are still in the shell, to eject. When you fire, the rod is off and the shell will eject 'cause the mag pusher pushes them up.

    I hope this helped!
