This is my new knex gun. It shoots about 20 - 30 feet, depending on the rubberbands. It used to be a crossbow but it wasn't sturdy enough, so I changed it into a gun.
Good range for what it is
No modified pieces
Not too comfortable
Handle looks weird
UPDATE: My new handle (shown in pic 2) is much more comfy than the old one and it is advisable that you build this instead!
ANOTHER UPDATE: My even newer handle and ratchet system (shown in pics 3 and 4) is even better than the previous update and it is advisable that you build this instead!
Now, on with the building!
Step 1: The Barrel Front
This is the front of the barrel
Step 2: The Main Barrel
This is the main barrel. The bullet slides down this.
Step 3: The Trigger
This is the trigger and trigger mech.
Step 4: The Handle
This is the handle. It is a bit crappy so I would advise that you modify it.
Step 5: Assembly
This is the fun bit.
Step 6: Rubberband Placement
This is where you put the elastics
Step 7: Loading and Firing
How to load and fire.
Hook the top elastic band around the orange trigger connector, put the ammo in, and PULL THE TRIGGER!
Step 8: Finished!
Have fun with your gun!!
