Intro: Knex Gun/Pistol With Dual Loading Magazines

This is a KNEX pistol I designed with dual-loading magazines that can easily shoot over 40 ft with good rubber bands, and can get farther with ore, or stronger rubber bands. It can hold 25 blue rods at a time, so you don't always have to reload. This is my first instructable to comment and critique how I did. Ask about anything that is unclear and I'll try to clarify it. Special parts: 4 decapitated gray connectors, 10 blue spacers, 1 orange rod from old roller coaster set as well as others (can be replaced by a red rod.) and a metallic blue connector like a tan connector with no tab (can be replaced by a tan connector though.)

Step 1: Handle

In this step you will create the handle of the gun:
1: build these.
2: Attach the yellow connectors with white rods
3: Diff. view.
4: Add on orange connectors with white rods on the bottom, and blues on the top.
5: Add yellow connectors to the blue rods on top. Completed.
6: Completed. Top view.

Step 2: Barrel

In this step you will construct the barrel of the gun which will connect directly to the handle.
1: Gray rod with 10 blue spacers and 4 decapitated gray connectors.
2: Two gray rods each with 5 tan connectors on them.
3: First two steps attached to two white connectors on the bottom, left and right.
4: Bottom view
5: Clip on six yellow connectors then slide one on a side for the block trigger and clip one more on after that.
6: Opposite view.
7: The pin, with two gray connectors clipped on with a white in between.
8: Clip the last step onto the back of the barrel and add an orange connector for the rubber bands.
9: Use gray connectors to space out the yellows. (You can use blue spacers if you want.) Make sure you put the designated gray connector on first.
10: Clsoe-up on the one you want to put on first.
11: These will be added to the bottom gray rod in the next step to fill in the barrel.
12: Leave two spots open for the handle.
13: Bottom view of the barrel.
14: Connect the handle here.
15: Completed barrel and handle.

Step 3: Magazines

In this step you will construct a dual-loading magazine.
1: All the parts needed to make the magazines.
2 thru 6: Close-ups of parts need for steps 7 and 8.
7: Make two of these. Top view.
8: Bottom view.
9 thru 10: Close-up of parts need for steps 11 and 12.
11: Top view of the parts put together.
12: Side view.
13: Side and middle pieces attached.
14: Add yellow connectors on both sides.
15: Connect the blue and yellow connectors with blue rods.
16: Bottom view of magazine so far.
17: 2 yellow rods and 2 rubber bands to keep ammo in magazine.
18: Placement of the last step.
19: Piece for the loader. (Orange connector, orange rod and small metallic blue connector.)
20: Insert through yellow connectors from step 14.
21: Side view of magazine with loading pin in.
22: Bottom view
23: Wrap a rubber band around the magazine and orange connector of loading pin to keep it in place.
24: Attach magazine to barrel here.
25: Magazine and barrel attached.
26: Loader in the left position move to the right to drop a rod in from the right.
27:Loader in the right position move to the left to drop a rod in from the left.

Step 4: Loading and Firing

To load the gun insert the blue rods into both sides at the top of the magazine.
Then, move the loader from one side to the other to drop a bullet down.
Pull back on black rod till it locks, and lift the block trigger to fire.
To fire again just move the orange connector to the other side.

Have fun with my gun.

If someone could design a true trigger for it that would be great. Either post your version of it, or show me you trigger and I'll try to incorporate it into this. Thanks for viewing my Instructable!

    50 bullets in one gun is way enough using a chain fed mg would be a waiste of time.
