Introduction: Knex OSSR

Picture of Knex OSSR

Don't build this gun, build this gun instead

Step 1: Stock (optional)

Picture of Stock (optional)

Believe it or not, this stock is optional. It isnt needed for performance, just adds looks and a brace for the arm.

1- build 2 of this frame, note the blue rods and orange connectors.
2- back of stock.

Step 2: Handle

Picture of Handle

The handle. Simple.

Step 3: Main Body, Trigger, Saftey

Picture of Main Body, Trigger, Saftey


1- build these parts. They will be the trigger parts. Read the notes to find out what each part does.
2- the body
3- the body from the top
4- add the trigger part. (the one on the bottom)
5- Gather these parts (2 are optional)
6- add to trigger. By now you may have noticed how the safety works.
7- Add trigger guard
8- add the last part from picture 1 to the top corner.
9- Attach handle to body.
10- Attach stock to handle and body (that is, If you made it)

Step 4: Barrel

Picture of Barrel

Erm, whut?

1- the bulk of the barrel. make that, note all blue rods, orange connectors, and spacers.
2- the part that connects to the body (note all blue rods)
3- view of the other part (near the front) Note the 2 y connectors on the bottom and blue rods
4- foregrip
5- attach foregrip
6- top view of barrel. Sorry for blur.
7- The end of barrel
8- attach the end to the rest of barrel.

Step 5: Final Connections

Picture of Final Connections

Connect barrel to body.

1- separate view
2- connect

Step 6: Rubberbands, Loading, Firing

Picture of Rubberbands, Loading, Firing

Yay, you are almost ready to fire this gun!

1- Trigger rubberbands
2- Rubberbands for the oodammo holder
3- my method of looping the rubberbands
4- Hooking the oodammo to the rubbberbands and loading it into the holder.

Now pull the trigger, and fire!

Thanks for viewing!

I have an idea: Why don't YOU make a parts count?  You are the one begging for one.

Is there any way to mod a sipriani style crossbow into a slingshot mechanism like this?

I really don't know. Maybe you could build the trigger and then put the crossbow around the mech.

MegaMetal8 (author)2010-12-07

Don't have enough pieces for the OSSR-2, whats this one like?

DJ Radio (author)MegaMetal82010-12-08

It's basically a less sturdy version of the OSSR-2. Obsolete by today's standards but it's still the only slingshot with a lock on the trigger.

MegaMetal8 (author)DJ Radio2010-12-08

By lock do you mean safety?, or the firing type were you clip it onto the y-clip?

DJ Radio (author)MegaMetal82010-12-09


MegaMetal8 (author)DJ Radio2010-12-09

Ok, might build in like january because im building Owenmons break action shotgun

MegaMetal8 (author)DJ Radio2010-12-08

Oh yeah thanks for 1500 comment

Jesus. (author)2010-04-10

Meh. It's OK.

DJ Radio (author)Jesus.2010-04-11

I agree seeing as how this was posted a year ago.

Oblivitus (author)2010-02-27

Did this get featured a while back?

DJ Radio (author)Oblivitus2010-02-27

Yes... Some guy unfeatured it though.  Oh well.  Why you ask?

wehe-tehe (author)2010-02-18

this to a point looks like the nerf longstrike coming out

DJ Radio (author)wehe-tehe2010-02-18

I, to a point, don't care.

PindaHoofd (author)2009-11-09

I build it. It's isnt as heavy as i tought.
BUT! the trigger didnt work so i broke it.
Still it was a very cool gun.   4*

 trigger sucks

DJ Radio (author)matsermetsuiker2010-02-16

Weird, it always worked for me.

I know. It didn't work. (for me)

DJ Radio (author)PindaHoofd2009-11-09

You should put bands on the trigger or use a fresh Y connector.  Mine always worked.

PindaHoofd (author)DJ Radio2009-11-10

I made everything good and i already put bands on the trigger.
And what do you mean with 'fresh Y connector' ?

PindaHoofd (author)PindaHoofd2009-11-10

Wait, i get it. Actually the problem was that it was too fresh.. xD
It didnt release the oodammo so it didnt shoot.

DJ Radio (author)PindaHoofd2009-11-11

Either put more bands on or band it like I do. 

J Moneyman (author)2009-11-29

hey, if 1337 means leet, then what does 4363 mean?


sounds legitamate! :D

J4mm3r5 (author)2009-11-30

 anyone know where I can get some thick elastic bands in the UK??

Millawi Legend (author)J4mm3r52010-01-15

finmonster (author)J4mm3r52009-12-21

i do in an epsom model shop it has immense ones that are really thick and strechy

DJ Radio (author)J4mm3r52009-11-30

Office supply store?

DJ Radio (author)2009-12-23

Sorry, I can't help you, by the way, how the heck would a part count have anything to do with your problems?

1 hour time limit is for suckers.

DJ Radio (author)2009-12-23

Why do you want one anyways?  This gun doesn't use a lot of parts.

DJ Radio (author)2009-12-23

Do you seriously think I have this gun now?

DJ Radio (author)2009-12-22

I'm not being mean, I'm saying that there are no parts lists available. 

DJ Radio (author)2009-12-21


dutchwarlord (author)2009-11-21

great gun
and yes this is that is the best snoop dog song

DJ Radio (author)dutchwarlord2009-11-21

Wanna build?

ajleece (author)2009-06-29

Hmm..... Maby I'll add it to my arsenal. But I don't build slingshots these days.

NYPA (author)ajleece2009-10-30

Knexsayer, BR-18, Rising sun, AST pistol and oodassault. Am i wrong?

ajleece (author)NYPA2009-11-04

Nope. Correct

NYPA (author)ajleece2009-11-04

Skill. I has it.

DJ Radio (author)NYPA2009-11-06

Nah, you just have recognition for famous guns.

noobererer (author)ajleece2009-06-30

you need a sniper! and slingshot guns are the perfect sniper rifles!

ajleece (author)noobererer2009-06-30

I can't build them. If I get caught with one that shoots I might get in trouble. I might also kill someone. Also, I ran out of rubber bands.

Why, would you shoot someone??

Why wouldn't you shoot someone?

Why would you if you know you will get in trouble and possibly injure someone

DJ Radio (author)ajleece2009-07-01

dont put rubberbands on!
