K3 is my new knex pistol, it uses a NEW mecanism to prime the gun, instead of pulling back on a firing pin, you simple cock the top slide back. Like a airsoft gun, or a pistol. It does use quite a few pieces... but it is well worth it.

here is a video of it working

Step 1: Building the Bottom Slide/barrel.

Follow the pics below to build the bottom slide of the K3 pistol.

Step 2: Build the Top Slide.

Follow the pics below to build the top slide for the gun.

Step 3: Build the Handle.

Once again, follow the pics below to bulid the handle.

Step 4: Adding the Trigger

Follow the pics below to corectally wire the trigger into the gun, this step is a bit dificult... so pay close attention

Step 5: Build the Ram Rod and Add the Rubber Bands.

Folow the steps below to build and attatch the ram rod.

You will need to take the top slide off the gun in order to corectaly put the rubber bands on the gun.

Step 6: RE-attatch the Top Slide, and Add Its Rubber Band.

Look at the pics, once again you will need to pay close atention to how it all goes together.

Step 7: Your Done! (how to Shoot.)

Congrats, you have sucsessfully built your very own K3 pistol. cool.

To shoot:

2.Release the top slide, it should jump back to its original position, and leave the ram rod cocked.
3.Put a blue rod into the barrel.

5.Aim
