Introduction: K'nex China Lake Grenade Launcher

Picture of K'nex China Lake Grenade Launcher

Again all grammar comments will be removed!!!!

*Edit*  at the last few pictures I made the gun somewhat longer. I'm still working on it but when I feel it is done I'll post.
If you have any critisism on the gun, please be clear about what you think should be better

This is another knex gun I created.
Recently I made Shadowninja31's MP5K, and I wanted something else when I removed the Handle and the mag I thought this looks like a grenade launcher! so I started removing and adding parts and this came out.
If you want the working pump you'll need those black rods you can do it somewhat different, if you don't want it to move.

I give credit to:
Knexguy ------> I used/ modified his stock
Shadowninja31-------> the inside of the gun is based of his MP5K
and anyone who thinks he needs credit

 Well, lets go to the pro's and cons

- (!I think!) it looks good.
- Good power/range.
- Has working pump, but with no function.
- Mag fed.
- Nice sights. (now foldab

- Hard to load a shot since the ram rod is in the stock.....
- Sometimes shoots two rods instead of one (but it gives it more a grenade effect.)
- Non-removable mag (but the real thing hasn't got one either.)
- Not (very accurate.)
- Two broken white rods are needed.
- Maybe a little small for some people

feel free to ask any questions .
I'm thinking about posting it so if alot of people want me to post I will.

Respect holmes.

You got alot more creativity than others.

Mite want to make a step-by-step for it.....

AUG-5OM3 (author)Doc Penguin2014-08-21

Thanks! Instructions have been up for a while, its more for looks than actual shooting though.



Looks like a combonation oh the Magnum from Halo, and a P90 from COD.

Yeah. That was a year ago. BTW, the P90 isn't from CoD, its from FN Herstal.

gast ik heb van iemand gehoord(en hij weet die shit)
dat dit gwn een tumper heet eue"

AUG-5OM3 (author)Kona-chan2013-12-03

Een Thumper heeft een knikmechanisme en de China Lake heeft een pomp mechanisme. Dus volgens mij is wat ik hier heb een China Lake.

Kona-chan (author)AUG-5OM32013-12-08

t heet officeel een thumper, de chinalake is een bijnaam, in werkelijkheid heten ze allebij de thumper, alleen dan met een knikmechanisme of een pomp

knexsuperbuilderfreak (author)2013-11-28

the con " Not (very accurate.)" i think is almost a pro, because this gun is legit never accurate.. xD

Kona-chan (author)2013-05-23

damned sexy v.v

Puddock (author)2011-12-08

This is a cute little gun. I like it!

AUG-5OM3 (author)2011-06-17

Wierd in what way? (And thanks.)

headlessknight (author)2011-05-10

AUG-5OM3 (author)headlessknight2011-05-10

I will relax!
But not just now I'm really buissy

headlessknight (author)AUG-5OM32011-05-10

sorry about that i just like grenade launchers take you time

AUG-5OM3 (author)headlessknight2011-05-10

I wasn't agry or something but it wont be sped up by asking much. I'm really loaded with schoolwork, so sorry about delay.

headlessknight (author)AUG-5OM32011-05-10

it's ok i know how bad schoolwork is

headlessknight (author)2011-05-08

just can't wait to build this when he post it

headlessknight (author)2011-05-03

dude hice grenade launcher i've been try to make a china lake but it always
ends up looking like crap. POST IT POST IT please if you feel like it.

AUG-5OM3 (author)headlessknight2011-05-06

Two more things before I post. Barrel/stock connection more sturdy, and I want to make a storage room for extra ammo. If that's finished (probably two days for creating/improving.) I'll post it.

And thanks for the help

headlessknight (author)AUG-5OM32011-05-06

try making a second mag well in the stock

AUG-5OM3 (author)headlessknight2011-05-07

I made the mag in the stock, it can 4 bullets in the stock extra.
I'm probably posting it tommorow.

spartanskunk (author)2011-05-06

um maybe you shouldn't call it a grenade launcher if it doesnt shoot grenades,but its pretty hard to make a realistc greade launcher that shoots grenades. nice replica though

AUG-5OM3 (author)spartanskunk2011-05-07

Yeaah, it doesn't shoot grenades. But I reckoned not everyone knows what a China Lake is. On first sight it could also be a shotgun. And it's too bad I couldn't make it fire something that "explodes"

DJ Radio (author)2011-05-03

Looks a bit too short if you ask me. The ADS part seems too short as well.

AUG-5OM3 (author)DJ Radio2011-05-04

that's good critisism and yes it is a bit short i'm still working on it but I wated to show the progress
and what do you mean with the ADS is to short? should I enlarge the sights or something?

DJ Radio (author)AUG-5OM32011-05-06

Height-wise it is too short. The sights in the game were a lot taller than on yours.

AUG-5OM3 (author)DJ Radio2011-05-07

Ah, okay thanks. I'm still working on iomproving the sights.

AUG-5OM3 (author)2011-05-06

before I'm going to post it, I need your help. The blue connector where the body ends, and the stock begins that part is kind of flimsy. I'm trying to improve that, but not a good result :-( If any of you has got any tips, please sent me a message on my orangeboard. If you need any pictures, just ask.

Raz1r Knex Bull3t (author)2011-05-04

Cool Beans : ) . 5*s.


It's a quotation/saying.

ah okay

chopstx (author)AUG-5OM32011-05-05

haha yes, beans

headlessknight (author)2011-05-04

post it post it post it please

AUG-5OM3 (author)headlessknight2011-05-05

I will, but not yet. I first want to improve it.

headlessknight (author)AUG-5OM32011-05-05

ok thanks

TheFoofinator (author)2011-05-03

Nice. If you made the pump bigger, so it surrounds the mag, you have yourself the beginnings of a decent pump-action!

AUG-5OM3 (author)TheFoofinator2011-05-04

the pump has no function, and I made it that short on purpose so you can move it.

TheFoofinator (author)AUG-5OM32011-05-04

Note I said 'beginnings'. With some mods this could work with a real pump. I like the mag.

AUG-5OM3 (author)TheFoofinator2011-05-05

yeah I could try that

AUG-5OM3 (author)2011-05-04

I just made the barrel 4 connectors longer and the stock three, so it looks larger. I also replaced the pump rail

knexinventer (author)2011-05-03

post 5* sub

AUG-5OM3 (author)knexinventer2011-05-04

~KGB~ (author)2011-05-03
