SRv2

If you don't have any K'nex and want to buy the parts for this beast you'd better fork out $140 and you won't get much change!
With a proven 500ft+ range! Enjoy the video, and if the thought "This is pretty good" even briefly crosses your mind, don't hesitate to rate 5 stars!
BUT! If you don't have the parts to build this gun, then go straight to step 6 for part savers and mods.

THE OLD VIDEO IS NOW ON THE LAST STEP! Watch if you want to see the SR-V2 at close range!

The Last picture is what remained of the power gauge. (the white bit was all I could find from the first attempt, and I replaced it with a blue bit and shot from further away. I gave up after that!)

Step 1: Build the SR-V1

http://www.instructables.com/id/SR-v1/
WARNING! DON'T BUILD THE BITS IN THE YELLOW BOXES SHOWN IN THE PICTURES(BELOW)
I HAVE PICTURED WHAT SHOULD BE BUILT INSTEAD.
Oh yeah, don't bother with the bipod, its rubbish.

Righty ho, the trigger frame, Carrying Handle w/ Sight and the barrel all need changing! When you get to those steps, refer back to this intructable to see what you need to do.

Picture 1 and 2:
1) Right, see the grey connector (outlined in image notes), replace it with the hinge seen in picture 2.
2) Ignore ALL of this photo except where the hinge goes: my gun is different from the SR-V1 to save time, effort and pieced :D

Picture 3:
Ok, don't try and leave the barrel open, it will not need to be opened in anyway BUT do not attach the 3 blue rods that are circled in red.

Picture 4:
IMPORTANT: It is essential that you leave the gun in this disassembled state.

UPDATE!
SR-V1 parts list (This includes the firing mech too, so think of it as an estimate):
4x yellow
61x blue
288x green
244x white

Hey lowney check out the best knex sniper on this site:
http://www.instructables.com/id/SR_V2/

[T-man]

THIS IS AMAZING!!!! 5*

[lollolman148]

i fired it and the nxt day i heard on the news about knex being found on mars...

[Lowney]

lol

[metalsonic]

BEST. KNEX. SNIPER .EVER !

[knexsniper1]

Can someone explain to me how the trigger mech holds the bullet and prevents it from flying off??

[Lowney]

The grooves on the blue rod grip the end of the red rod. It doesn't really look like it should work but it does :-)

[knexsniper1]

awesome! Thanks for explaining :) Btw, are you still an active knexer??

[Lowney]

Not really, I no longer live at home (where the knex is), but sometimes I visit and if my younger siblings or whatever want me to help them build something I will, and if it's awesome I might share it :P
I'm more into YouTube now, I do a lot of speed arts and such, my channel is (totally shameless plugging ;D) www.youtube.com/Lowneification

[knexsniper1]

Ohh ok. Cause I was wondering if you'd be willing to collaborate with me on a project? It's a sniper that I was working on

[Lowney]

Yeah sorry, I mean feel free to use any of my mechanisms or parts of any of my guns, I don't mind, but I guess other than that I probably can't be of much help, sorry! But if you're stuck with anything (like can't get a removable mag working or whatever) feel free to inbox me :)

[knexsniper1]

Aright! Check your inbox soon, I mentioned the design of the gun

How many of the hinge connectors do you need?
I dont have any but Im sanding down grey connectors with a dremel. So far Ive made one complete one and it works perfectly

[Lowney]

Well you need two of the green/black coloured ones, and then you need a pair that actually "connect" and work as hinges if that makes sense. The third picture in step 3 shows how they're all arranged :)

[darthbindy]

since i dont have enough knew to build this (i think) i only have a box of about 20 pounds but i dont think it has the right peices, so im going to make one of these out of wood and piping........yay! might post it wen done................

[Lowney]

Sounds awesome! Send me a link on my orangeboard if you do!

[darthbindy]

*knex, not knew

[PotatoCoffee]

A bit of constructive criticism, the stock is pretty weak looking, (very skeletol) and the barrel seems to curve down (probably the weight). I realise this was your first knex gun so I'll let you off!

-PotatoCoffee

[Lowney]

What part of the stock is skeletal?

[PotatoCoffee]

Image belongs to Lowney

The very end of the stock.

[Lowney]

If you're talking about the bit with the red connectors and white rods (the vertical bit) I deliberately made it like that because it bends to the shape of your shoulder much more easily than a normal stock. Since I appreciate most people don't like this the normal stock is in this instructable.

[PotatoCoffee]

Oh okay sorry 'bout that.

[Lowney]

Whilst I don't mind you showing me stuff like this on my orangeboard, I'd appreciate it if you didn't place these links on my actual instructables since it's blatantly just trying to steal some traffic and you'll probably get a negative reputation on the site if you keep it up. Especially if said instructable has a relatively high view count.

[PotatoCoffee]

Sorry!

[DracoUltima]

When will you change the instructable and say that this gun did not reach 500 feet? Your video CLEARLY shows that the the bullet curved over the next house, meaning that it was only able to get 130 to 150 feet. I have built TWICE, put on surgical tubing until the barrel was about to snap, and it only hit 220 feet. I am almost positive that you admitted it sometime ago, yet, you never bothered to change this..... Why? Is getting more views and 5* worth the lies. There was no evidence of 500 feet. The little picture proves nothing, just change it so you don't misguide the beginner builders.

[Lowney]

Yup, the video does indeed show it curve over the next house. It's unfortunate that you cannot see the houses beyond that as it flew over them too. And no, I have never admitted that the video was fabricated, because it isn't. KILLERK can back me up here when I say that this gun is capable of 500 feet.
     One thing that you should understand is that I simply have no reason to lie about the gun's range. If, indeed, it couldn't shoot 500 feet I would say so. I would do this because this is not my own gun, so if anything I would set out to disprove its range, not prove it. It wouldn't affect my reputation as a gun designed in any way, shape or form as this is KILLERK's design. If this gun WAS my design, then maybe there would be reason to question the video.
    You sound almost angry that this gun has a high rating and lots of views, but you really shouldn't. 5* instructables are relatively common now, since it doesn't take too many high scoring star ratings to max it out. And as far as views are concerned, this isn't YouTube; I'm not making any money out of the views or anything, it's just because this is one of the more famous guns and I was the first person to publish an instructable on how to build it.
    To summarise...the video was not a fabrication, and there would be no point in me making a fake film anyway since the gun isn't even mine, and it would likely still have the same rating and view count if the range was lower anyway. 

[DracoUltima]

Actually, I was pretty pissed about something that day (something personal), but I still don't believe that this gun reached 500 feet, as I have tested it myself. I won't argue any further as it will solve nothing, sorry if my comment from before sounded harsh. You can stay with your statistics and I'll stay with mine.

[zbrown2016]

Um ha ha how do you stick the bullet in there. Um I can't figure it out

[Lowney]

Just look at the photos, it's pretty easy. There are more photos on my compact SRv2 instructable if you're still struggling. You have read step 4 right? :)

[zbrown2016]

Ya but does it tell you how to put the bullet in

[Lowney]

Yes

[CODKING]

and the power is nothing like iv ever seen before its just insane. How durable is it like is hard to break it or does it withstand quite some force?

[Lowney]

I guess if you snapped it over your leg or something it would break, but providing you add ALL the blue rods in the barrel, if dropped on concrete, the damage to the gun would be very trivial, the handle would probably fall off but that's about it, and even that can be avoided by using strengthening beams shown on pictures 3 and 4 of the intro

[CODKING]

damn im gonna have to get a lot more yellows if im gonna build this i hope i can find some cuz this looks pretty fun to build to especially to pass the time

[tincanz]

This is incredible!
The best I have ever been able to get with my guns is around 40 feet.
This style of your's though, had not occurred to me....

So, is it simply a gigantic slingshot?
It seems that the bullet is pulled directly by the rubber band(s), and the barrel length is only for the bands to cume to full stretch. Correct me if I'm wrong but this is a slingshot with a mechanism to control release.

This design is intruiging!

[Fred the evil puppet]

where does the mechanism clip onto on the gun?
