Pico-power K'nex Gun





Introduction: Pico-power K'nex Gun

Smallest K'nex gun on instructables that I know of. It uses only 9 pieces. It can shoot up to 15 feet but it can be less or more depending on the rubber bands you use.

UPDATE!!! put a new rubber band on it and reinforced the gun with duct tape(also makes it look cool)and used a bb as ammo... it hit my bathroom wall 30+ feet away with a good amount of force

Step 1: The Parts You Need

You need,

2 double ended orange/brown
4 single clip gray
1 two clip gray white

2 small blueish silver rods
? small black/green rods (for ammo)

rubber band(s)
sand paper

Step 2: Build the Gun

Use the picture below to build the main part of the gun

Step 3: Make the Fireing Pin

Use the picture.

Also look at the other pic. I recommend that you sand the end of the pin that goes into the barrel so it doen't catch something in the barrel and make it misfire

Step 4: Prepare to Fire


Step 5: Fire!

    i didnt have a black piece so i used a lite brite peg. not as effective, but works. if got it to go 10-15 feet. i also had to substitute the blue pistion for a white one for strength on pulling back.

    block trigger...stinks....trey the trigger from the okp it's 1000% better i mean it it actually is better tenfold

    i sellotape a magnet 2 it nd my hand so u can just shake ur hand n it shoots lol :D

    I made a modded version with a sight increased stability for the firing pin and an addition to the trigger to stop the bb falling out of the end
