Introduction: K3 Knex Pistol. *new* Shooting System

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
http://www.youtube.com/watch?v=DLN0uF7uZvU

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:
1.Pull back the top slide of teh gun to cock it.
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.
4.Put your finger on top of the rubber band that holds the trigger. (inbetween the rubberband and teh bottom of the gun.)
5.Aim
6.Pull the rubber band downwords.

The shooting mechanism is VERY inconvenient. I really like the trigger idea though urah03!

On a scale of 1/10, this is a 2. Sure, it has a cool look, and you load it differently, but: a) Hard to load. If you pull back to far, the slide and ramrod comes off, whipping you in the hand. Also, you usually have to push the trigger into place. b) Bad range. If you DO manage to load it, it has almost no range, even though it goes straight for the floor and skips a few feet. c) It uses 3 rubber bands. for 3 rubber bands, it should go as far as the Fruit Fly. That thigh shoots far. And you only need 2 bands. This thing, goes nowhere slow. d) High k'nex usage. A good gun only needs a few pieces. This went through all of my semi-circles. Overall, don't build it. Keep the creativity, but troubleshoot BEFORE posting it.

agreed on all, except the last statement. all good guns have true triggers, and many use more pieces. u also forgot to mention that this is a block trigger...

author
Oompa-Loompa (author)DJ Radio2008-07-22

you mean so many pieces, and no trigger attached to the block? It does look pretty cool though.

author
DJ Radio (author)Oompa-Loompa2008-07-22

yes on both counts

The top piece only has twenty two half circles not 24...I see that that can get confusing with all of the pieces. but its a simple mistake I just wanted to point that out to you. and by the way I like the gun it is very nice.
