Picture of K'nex Contest Entry: JS-9MM

Hi there,
this is my newest creation and also my entry for The Red Books of Westmarch's contest. It is the JS-9MM Submachine gun. Lets go the pros and cons shall we?

- Looks and feels great.
- Sturdy.
- High powered.
- Charging handle works as the firing pin.
- Nice simple sights.
- (Close) to scale.

- A bit bulky.
- Mag is non-removable.
- The handle is the only part that is a little wobbly not that big of an issue.

I give credit to:
- Selziona for the ram idea and the angled front part
- Knexbuild for a part of the trigger

That's about it. lets get building.

Step 1: Outer Panels

for some reason your stuff doesnt come up on my page when you post it. I know it's old but I haven't seen it :?

Weird... You're in my subscribers list i know that, but sometimes my instructables is acting strange too.

stubbopolis (author)2013-01-18

Looks Great! I think i might try for a removable magazine but i haven't built knex in forever

AUG-5OM3 (author)stubbopolis2013-01-19

Thanks and go ahead! If you manageto make it could you post some pictures of it here?
I'll see if I can put it in the instuctable.

stubbopolis (author)AUG-5OM32013-01-20

sure thing

CODawesome (author)2012-12-10

Looks pretty darn accurate to the real one, but IMO it is short in length. the stock is too short, looks like a machine pistol instead of an smg. but it still looks great

AUG-5OM3 (author)CODawesome2012-12-11

I agree the stock is about one connection too short, but I don't have it anymore.

L1keABoss (author)2012-12-06


AUG-5OM3 (author)L1keABoss2012-12-07

Thanks alot!

CODawesome (author)2012-11-10

Looks exactly like the chicom CQB featured in black ops 2, but without the carrying handle

AUG-5OM3 (author)CODawesome2012-11-11

Okay... I don't know I don't have BO 2

Knex.X (author)2012-11-03

Built it, great gun however the trigger doesn't work fine for me

AUG-5OM3 (author)Knex.X2012-11-03

What is the problem, exactly?

Knex.X (author)AUG-5OM32012-11-06

I broke it down and I just finished a Knexsayer. Anyways, the problem was that pulling the trigger didn't make it shoot. It'll be my fault anyways.

AUG-5OM3 (author)Knex.X2012-11-06

Mmm... That never happend with me? Okay maybe you put something in the wrong place.

Knex.X (author)2012-10-29

Looks great! any information about range?

AUG-5OM3 (author)Knex.X2012-10-29

No sorry. It shot pretty far though...

Knex.X (author)AUG-5OM32012-10-30

Hmmm, normally those types of guns don't shoot far, but oh well, since you say so I guess this one must be a one of its kind.

AUG-5OM3 (author)Knex.X2012-10-30

Well, Seleziona's Skorpion (V2) SHot pretty far and it's basically the same mech. It really depends on the Strenght and age of the rubberbands. Also In my newer version I stripped the Inner plates so that the 'bullet' has 2 connections space in stead of one (if you get what I'm saying.) also the pin goes back as far as possible giving it an advantage over a ramrod. Because that would be sticking out of the stock and would be bending, because a pin guid is impossible there

Hope this explains everything =D

Knex.X (author)AUG-5OM32012-11-02

Yup. So true, in fact, I got Selez' skorpion laying next to me right now :)

kwintisolo12234 (author)2012-11-01

it finally works!
i took out the inner plates like you suggested.
might make it into a L85

AUG-5OM3 (author)kwintisolo122342012-11-02

Cool I'm glad it worked out for you.

kwintisolo12234 (author)2012-10-31

i'll keep working on it , it finally shot normally

AUG-5OM3 (author)kwintisolo122342012-11-01

Thanks. You probably did something wrong the first time because mine shot pretty far. Did you use snowflakes or 3d-connectors? The 3ds cause more friction that could be a reason. Also a tip is to remove a part of the inner plates so the bullet has more space but also makes the gun alot less sturdy. :S

kwintisolo12234 (author)2012-10-31

wow! it shot an incredible 5 cm!
but seriously, i think i built something wrong

kwintisolo12234 (author)2012-10-31

built it today, still getting it to work.

TheAwesomestDude (author)2012-10-28

Very Nice, i would say 4.5 *

Thanks alot!

your welcome

JonnyBGood (author)2012-10-29

Nice gun. very accurate look to it.

AUG-5OM3 (author)JonnyBGood2012-10-30

Thanks alot! what gun did you make?

JonnyBGood (author)AUG-5OM32012-10-30

The QCW, but I really just focused on performance and did the looks later. In the end I ran out of time for either and just threw it together.

the-dutch-guy (author)2012-10-29

ooo this gun have to be awesome in akimo

AUG-5OM3 (author)the-dutch-guy2012-10-30

Thanks, I thought the same thing.
