"KWR-24" Knex Wrist Rbg




About: I've been building and engineering since as far back as I can remember. My first building toys were those wooden blocks, and at age 4, I upgraded to cereal box samples of K'nex. I also participate in sports,...

Something not seen before on this site, a rubber band gun mounted on your wrist! This was designed by me so I could easily hit my enemies in close quarter combat. By how you ask? By the fact that not only does it look like a knex wrist guard, it shoots rubber bands! and not just one per shot, it shoots two! Also, this is my first knex rbg that can shoot #64 rubber bands. This is it, a weapon for you to annihilate your opponents with in your next rubber band gun fight. But enough with this biased introduction, build it for yourself and see its ability.

Picture one is a top view and picture two is a bottom view. Don't forget to watch the video! (the first shot in the video does not fire because I pulled the gear back without putting ammo on it)

If you watch star wars you might be saying to yourself, "kwr-24, that sounds familiar" and thats because it is. In the star wars films, the wrist blaster system used by Jango and Boba Fett were called DUR-24 wrist blasters.

Step 1: Parts List

These will be the parts you will need to complete this build. Some might be a little high. Better to be safe than sorry though, right?


light gray-7
dark gray-4

"Y" connectors-3
1 weak band for the trigger
2 bands per shot (recommended size is #64 bands)

Got those? Lets get building.

Step 2: The Trigger System.

Not much different than my previous ones, other than the fact that it uses my new "dual white" rubber band holding section, rather than mr. radical ed's single one that is on all my other guns. Follow the pictures, if you need help, leave a comment.

Pictures 1 and 2 are two views of the same part

Pictures 3 and 4 are two views of the same part

Pictures 8 and 9 are two views of the same part

Step 3: The "barrel" of the Gun

Simple, not to hard, except for one part. Read the notes!

Step 4: The Pretty Much Rest of Gun Step

Yes, all of these parts are necessary. Yet they really are so diverse they shouldn't be in the same step. Oh well, here they are anyway. Read the notes!

1-4 build them all.

Step 5: Rubber Band Placement and Loading

Follow the pictures. Not too difficult.

watch the video if you haven't already.

Thank you for building, offer any suggestions on my orangeboard or directly on this instructable.

    There are numerous wrist guns on this site! PLEASE look around before making claims! Search 'samus arm gun' or wrist gun, I know there are at least THREE arm-mounted weapons. Sorry, but you're NOT the first.

    no, there are 2. One is a crappy block trigger that hurts, and the other one is S0lekill3r's arm guns on youtube.

    What, so you can steal S0lekill3r's arm gun and claim it as yours because it wasn't posted on ibles, but only on youtube? Besides, it was posted as a slideshow on ibles, and Knex_builder_Freak made an ible about it.

    there's that crappy block trigger one, two samus arm guns, s0lekill3r's arm guns, and my project PAWS might also count. That's 5.

    Yes I am sorry about not making that clear, what I was meaning by that is that this is the first wrist mounted rubber band gun on this site. once again, I am sorry about that, in fact I will change that now.
