A block trigger muzzle-loading K'nex pistol. These are my favorite K'nex guns, both because of ease of use and high power. It even has a sight-ish piece on the side, although I've found it easier just to aim by pointing the gun in the general direction of the target from about chest-height.
By flipping the trigger over to the other side you can make a left-handed version of the gun. You also have to flip the blue and silver rings and the sight.
Modifications and suggestions are welcome. Just make sure to leave a comment!
Note: You need to look at all of the pictures to know exactly what I'm telling you to do. Some steps are rather hard to explain, and are best shown.
Step 1: Gather the Parts
Note: Rods are the long, thin pieces and connectors are the pieces they snap into.
Normal colors will be given first, then metallic colors. I used metallic colors where possible when building this particular gun.
For this Instructable you will need:
13 yellow or grey half-circle connectors
2 orange half-circle with knob connectors
2 purple or silver half-circle notched connectors
3 red or dark speckled grey quarter-circle connectors
3 grey one-opening connectors
1 green or black small rod
3 white or silver small rods
2 yellow or dark grey medium rods
3 red or green long rods (note: orange rods are the same size, but they cause too much friction to be used for the pin and do not fit as the side bars. Use of them is inadvisable.)
3 small blue rings
1 large silver ring
2 fat brown rubber bands (#64)
1 long rubber band
