K'nex Gun





Introduction: K'nex Gun

Most idea's 'borrowed' from KillerK's gun LOL.

Step 1: THE PARTS (only for the Barrel Part Because It's the Most Complicated for the Entire Project.)

Gather the following pieces for JUST the barrel, this does not include the rest of the gun, so keep your K'nex bin at arms reach.

Step 2: Build the 'Barrel' of the Gun.

Here is the barrel of the gun, it's pretty self explanitory. Be sure there is room at the rear of the barrel for adding the two elastic stands.
Be sure to look at the other angles of the barrel so you get it right!

Step 3: Front of Barrel Construction.

Here's a simple preview just so everyone understands the front piece of the gun. :)

Step 4: Rear of Barrel Construction.

Add these two pieces onto the back and then tape the connection so they have room to bend without snapping off incase you put on to many rubber bands. :D
And then add the two small black connectors on the underneath of the gun shown in picture two of this step.

Step 5: Ram/Sniper Rod

O.K. For this step I was basically forced to use a gray piece because my black 'sniper rod' or whatever was in use in my other gun and i didn't want to take it out.
So I just used a gray rod, but you could use the black rod if you want to, it would most likely increse the performance even though this gun already shoots a good 200 feet.
I also have hotglued the end of the pieces and then wrapped them in tape **WHILE THE GLUE IS STILL WET** to make the gun able to with stand a ton of rubber bands.


Step 6: Trigger Device Elastic Assembly

Here's a short description on how to add the rubber band on the trigger.

Step 7: Front Handles and Elastic Tracks ( Three Connection Red Pieces.)

Take about 5-6 Three connection red pieces and put them on two blue rods, (or longer if you please)
and then take another two and put them on the top of the barrel onto the last set of the short black connectors.
Those will help guide the elastics to keep it all clean. :)

Step 8: Sniper Addition.

Here is the sniper addition, it's completely unnecessary, but it add's a bit more accurassy + looks pretty sweet. ;)

Step 9: Connecting Sniper Addition.

Pretty self explanitory as well, but here you go.

Step 10: Elastic Assembly + Rear Handle Assembly

Heres the steps for putting on rubber bands for the most power, you must guide them back onto the ram to avoid them breaking/falling off everyshot
it should be able to hold as many as you put on there untill the gray rod starts to bend, but NOTE: you could put the black sniper rod on and it would increse the amount of rubber bands you could put on it probably. :D

Step 11: Bottom Elastic Assembly

Here's where you put the elastic on the bottom to balance out the leverage so the rod does'nt bend as much, it helps alot with power and strength throughout the gun.

Step 12: Loading Amo!1!!!

This is how you load the amo into the gun, even though most of you already know that. LOL.

Step 13: Completed Gun!

Your gun is now complete!
There is a slight preview of how far the gun shot for me with only 3 weak ass rubber bands and a yellow rod as amo, when you put more on the farther it shoots.
but if you put to many it can break the gun apart, so be careful!

    The gun is soooooooooooo cool!!!!!!!!!

    i cant fit the two bits on the rear in step 4, i can only fit one. do i take away one of the green conectors? someone please help!!!!!!

    i used the black knex rubber bands that come with.. umm... i forgot.. but they are REALLY good. i only use 4, and it doesn't shoot 200ft (i dont think) but its far enough and STRONG enough. the best thing about this gun is that it doesnt take a lot of effort to pull back the rod. some guns are really strong but are a pain in the ass to cock and fire. i shot my sister with this and it made a HUGE red mark on her thigh. good times.. good times.

    Mine shoots a lil over 100 and i got only 2 rubber bands. i got a ton for free and their almost 0.8CM thick and 5 inches long.

    to sharpen tip put in pencil sharpener works very well electric though

    Dude how many bands to you need to hitch to make this go 200 friggan feet dude this gun owns!

    This thing rocks! I'm a beginner with Knex guns.... I used the minimal amount of bands, and still got an average of 25-30 feet with a yellow rod. But it broke because i was attacked by my creepy sister, because i shot her from halfway across the house. Fun times... Good job though.
