Introduction: OSSR-2

Picture of OSSR-2

The new acronym that "OSSR" stands for is "Old Skool Slingshot Rifle".

Some background for the gun: Users had plenty of complaints and mods for the original OSSR, and I was having problems of my own, so I decided to remake this with the design changed up and filled up.  The mods resulted in almost every flaw in the original OSSR being eliminated.  It was so good that I decided to post it.

Anyways, if you have a problem or a mod to add, post it in the comments.  Photos and videos of problems and mods are appreciated a lot.  Thank you.

EDIT- Video:

This sniper rifle placed 3rd in megametal8's sniper contest.  That may not sound like much, but seeing as first and second place were replicas and mine was the only winner that was just made for pure performance, well I'll leave you to judge it at that.

Step 1: Before You Begin

Before you begin, get out an MP3 player and save the song below to it.  Go turn the "Repeat 1" option on, and listen to this while you work.  It helps a lot while you work.

Step 2: Stock

Picture of Stock

This stock may be harder and more time consuming to build due to the fact that it is filled up and thus sturdier.

1. Overview
2. View of the top from the hole where your thumb goes through (that's what she said)
3. View of the back without the part.
4. View of the top
5. View of the bottom
6. Make this special part and gather the red connectors.  Credit to Bakenbitz for it.
7. Place it here.

Now set it aside for later.

Step 3: Handle

Pretty simple.

1- Build what's pictured
2- another view (bottom)
3- last view (top)

Moving on...

Step 4: The Mechanism

Picture of The Mechanism

This is what makes the gun work.  This has a much stronger trigger than the previous version, and still includes the safety.

1- Make the frame sides
2- Trigger
3- Make this
4- Connect the 2 frame sides
5- Insert the trigger
6- Put another part on.
7- Gather these
8- Add the blue rod here.
9- How to clip the other 2 parts onto the blue rod.
10- Connect to handle
11- Connect stock to handle and mech (optional)

Set this chunk aside and move to step 4.

Step 5:

Picture of

Ok here's the barrel.  This is 5 layers thick, so when making this, think of it as 1 layer and make 5 of each and put it on the blue rods to make what is pictured.

1- Rear of barrel
2- Underside of the barrel
3- Midsection of the barrel
4- Front of barrel
5- Make this
6- clip it here
7- You should have this.

Gather everything and move on to the next step.

Step 6: Assembly

Picture of Assembly

You know the drill.

1- Gather the 2 sections and 2 blue rods and 6 green rods
2- Attach the stock and barrel together and insert the 6 green rods.
3- Insert the 2 blue rods where pictured.  This makes a nice trigger guard.
4 and 5- 2 views of the foregrip
6- Add it here.
7- Make this
8- Mind the 2 white rods in the connectors
9- Connect here
10- Add 2 green rods to it.
11- Add a rubberband to the trigger.

Step 7: Bipod (optional)

Picture of Bipod (optional)

Here's the bipod.  It is optional for those of you who don't want frivolous extras.

1- Make this
2- Make this twice
3- close up of the top
4- close up of the foot
5- attach all this to a yellow connector
6- insert this blue rod
7- Attach to the barrel

PotatoCoffee (author)Furloy2012-08-19

I wuz gonna' say that!

DJ Radio (author)anres3212010-09-21

Please don't post in my ible. And you need pictures.

anres321 (author)DJ Radio2010-09-21

here it is

DJ Radio (author)anres3212010-09-22

Can you please put a REAL handle on it?

PotatoCoffee (author)2011-12-17

Looks great!

mahmel (author)2011-08-04

great, but I can't see how you can stand that handle

DJ Radio (author)mahmel2011-09-06

I have knobs on it so I don't feel rods poking my hands.

mahmel (author)DJ Radio2011-09-07

Yeah I saw, but don't you prefer a 3 layered handle?

DJ Radio (author)2011-04-24


DJ Radio (author)2011-04-24

That's normal.

DJ Radio (author)2011-04-24

Yes.... In the middle of the 2 snowflakes is a tan lock.

Fred the evil puppet (author)2011-04-13

I prefer the first one.

I don't.

Dirtyboyy (author)2011-03-23

can it shoot so far as the srv2 ? with the same trigger mech or would the Y connecter break ?

builder968 (author)2010-07-04

I see a build in my future. Looks awesome, but I'm not going to rate until I build. Oh, and what's the range on this?

DJ Radio (author)builder9682010-07-04

I don't know the exact range, as I never did any proper tests. I'd say around 70 with 1 band.

buse66 (author)DJ Radio2010-11-26

bull, you told me a gun would"nt even go 40 with one rubber band!!!

Millawi Legend (author)buse662011-03-20

He has forgotten more about K'nexing than you will ever know. And he hasn't forgotten much, I hope.

DJ Radio (author)buse662010-11-27

This is a slingshot. I was talking about guns with firing pins when I said that to you.

builder968 (author)DJ Radio2010-07-06

Cool. I just took apart Seleziona's AA-12, so I'll get started soon. The stock doesn't look that great to me(no offense), so I'll make a different one and post a picture if it's any good.

DJ Radio (author)builder9682010-07-06


builder968 (author)DJ Radio2010-07-06

Actually, the stock looks better than I thought. I'll probably keep that, and I might extend the barrel.

The Nomlack (author)2011-01-05

I built it and the range, power and accuracy is great!! my favourite slingshot gun ever!!!

The Nomlack (author)2011-01-05

LOOKS EPIC!!! im going to build it 5*

Fred the evil puppet (author)2010-12-16

are these instructions, or just pictures? i cannot tell.

Plain ol' pictures. If they were instructions I would have dissected all the layers of the stock.

buse66 (author)2010-11-26

ohh yea the bipod stays clipped all right, cool trigger system thow

KnexFreak360 (author)2010-11-17

I just finished my knex rifle based on your firing system so if you want to check it out it should be up in at least a day. Its called knex rifle updated fyi

KnexFreak360 (author)2010-11-15

KnexFreak360 (author)2010-11-14

DJ Radio (author)KnexFreak3602010-11-15


DJ Radio (author)2010-09-23

I have no real idea why it breaks. I might make a new trigger for it later on.

DJ Radio (author)(YOUR N2010-10-21

I don't care.

PieMaster777 (author)2010-07-11

DJ Radio (author)PieMaster7772010-07-14

That comment made no sense whatsoever.

PieMaster777 (author)DJ Radio2010-07-28

Slayer is a band

DJ Radio (author)PieMaster7772010-09-21

That. Explains. Everything.

dmytro509 (author)2010-08-25

awsome sniper

DJ Radio (author)dmytro5092010-09-21


StarkIndustries (author)2010-08-06

i love the sound that the trigger makes!

~KGB~ (author)2010-04-12

nice! 5* i made the v1 and it backfired every shot lol, guess ill have a try at this then!!!

DJ Radio (author)~KGB~2010-04-12

I don't get how it backfired if the rubberbands had its force going forward.  That is impossible unless you banded the first one wrong.

~KGB~ (author)DJ Radio2010-04-13

well i made it with my mates knex, so it must of been faulty, lol, he doesnt take care of his knex...

builder968 (author)~KGB~2010-07-04

Since it didn't work with his knex, you should have handed it to him, told him to shoulder it, and then tell him to shoot it. Now that's payback in their face(literally).

~KGB~ (author)builder9682010-07-05

lol, he would of got pwnd!

DJ Radio (author)~KGB~2010-04-15

Video now posted.
