Introduction: The C3 Crossbow

This is a very powerful crossbow which I created. It is fairly lightweight, has a range of 40+ feet, has a stock, and a sight.

THE MOD OF THE C3, THE C3.1 IS NOW UP: https://www.instructables.com/id/The-Lego-C31-Shotgun-Crossbow/ . IT IS A SHOTGUN-CROSSBOW, THE FIRST OF ITS KIND BECAUSE IT FIRES A SHELL WHICH RELEASES MULTIPLE PIECES IN ONE SHOT.

Step 1: Bottom Part 1

Some of the basic parts of the bottom needed.

Step 2: Bottom Part 2

In this step, we create another piece to put on bottom, then attach some of the previously made pieces.

Step 3: Trigger Gear and Placing Trigger Gear

This step shows how to build the trigger gear, and put it on the bottom part.

Step 4: Bottom Part 3

This finishes the bottom part, and is a pretty big step.

Step 5: Rubber Band Holders/ Front of Crossbow

Easy step.

Step 6: Assembling Top

BIG Step, but this mostly finishes the crossbow

Step 7: Finishing Crossbow + Assembly

Putting on the rest of the flat pieces, and putting on the foward handhold. Picture 6-8 is showing the correction of the mistake I made earlier.

Step 8: The Stock

Okay, well I didnt really show exactly how to make it, but the pictures are fairly clear on the parts. This was my first attempt at a real stock.

Step 9: Ammo, Rubber Bands + Loading

The ammo is a 2x2 brick with a thin piece on top. The trigger counter-weight rubberbands are 2 small rubberbands (a large amount of counter-weight rbs is not required due to the way this trigger system works). The firing rbs are 2 sets of 3 rubberbands tied together.

it worked very well. if found what worked best for ammo was a 2x3 with a 2x1(one of those with a connector piece in front) in front of it. on the top i put two 2x4 flats. I turn the ammo upside down so it is smooth on smooth when fired
