True Trigger Knex Gun/Pistol by Bannana Inventor

Thank you for viewing this gun. In detail this it a knex pistol it isn't modeled after any real pistol, however with the right rubber bands this gun is very powerful and accurate. When reviewing this remember that this is only the second gun/Instructable I've made so go easy, please.


Step 1: Starting the Gun Handel

Build what you see, in case you are wondering the blue pieces are rods sticking up.

Step 2: Build This.

This is what you should have now, but also add the second layer of the handle, there is also a gray single connector don't forget to connect that!!! (bottom of the handle) The blue rods go through the orange connectors' holes in case you were wondering.

Step 3: Build This.

Build what is in the picture.

Step 4: Final Handle Step

Take what you've just made and attach it all together, and congrats you have built the handle of the pistol!!!
P.S. Don't forget the other gray single connector at the bottom left of the handle.

Step 5: This Is the First Part of Making the Tail End of the Gun.

Build what is in the picture. Once again the blue pieces are blue rods sticking up.

Step 6: Build This.

Build what you see in the picture.

Step 7: Build the Trigger.

ba style if you know what I mean.

Step 9: Build the Ram

Step 10: Build This.

Step 17: Adding Rubberband.

Add the rubber band as the picture shows.

Step 18: Last Step.

Connect all the pieces together as shown and your done.
P.S. The gray rod on the ram should go through the orange connectors' hole. If you want a "real trigger" get some string and tie it around the trigger and the firing pin, or just make your own.


Step 19: True Trigger Addition.

1st pic, build the pieces. 2nd pic, connect as shown. 3rd pic, place trigger as shown on the gun. You will need to add the tan piece as shown in pic 3 and remove the original trigger.

    this is awesome!!!!! if you have problems with pulling the ram back but it falls out of place then move the blue rod nearest to the back (from the intro picture) one space to the left it should stop coming out.
