Introduction: (UPDATE) LKSS a Knex Slingshot Sniper

Hey guys! Sorry I haven't been active recently, I've been building but I haven't been happy with much I build lately but oh well. So this is my new LKSS, it's a pretty lame name but it stands for Lucas's Knex Slingshot Sniper. So I was thinking about slingshots and it hit me. On a normal slingshot the rubber bands are loosing tension the farther down the barrel it gets meaning the bullet gets ahead of the band which means loss of power. With mine the rubber band is at constant tension but is still relatively easy to pull do to the pulleys. It's not anything innovative but I wanted to try it out and sure enough, it is twice as powerful.

Stats
200 foot range with finnammo
90-100 feet with a yellow rod connected to a red connector
Goes through a card board box with ease
Comfy
Weird but cool looks IMO
Nice scope
Folding bipod
37 inches long
Cheek rest
No broken parts


So tell me guys what you think in the comments, I love hearing from you guys!

Step 1:

DONT Shoot this indoors. It is dangerous!

That looks powerfull.
Should'nt aim in the wrong direction or you'll be like that wall.

author

It is Very powerful. How did everyone find out about the wall? I told BM about it, then somehow it spread like wild fire. Or did I write it in the ible itself.....

author

Lol I forgot I put it in the ible. So that's why everyone knew about that.

looks great, and if it shoots that far, I am impressed.

It's good to see somebodies building, it has been a little quite recently, even from you!

Thank ye kindly! It seems like I've just ran out of motivation lately. For me to build a good gun I have to be exited to build it. Now I'll start a gun and it'll look like crap. I'm kinda in the mood to build a bullpup but I can't find a replica I like. Any suggestions?

I know exactly what you mean about building and you're put off when it looks bad, I haven't seemed to be able to create anything I am proud to call mine.

As for bullpups, famas, a-91, AUG, Barrett m90/m95, FN F2000, P90(sort of,) tar 21, kh 2002, L85/86, tkb 022.

Wow I guess call of duty was useful...

author

Probably not, it's very simple

author

Yeah I will give credit

author

Very cool gun. I have done a lot of research and testing on slingshots. With that being said the pulley systems ive worked on mostly on my SRv3 were less powerful than the simple tied ones. Technically tapered flat bands of latex or therabands are better than surgical tubing or rubber bands. Long story short from what ive seen tested and read the pulley system is not as good as a straight tie band set. I could go on and on from my days and days of research and development but i am yet to discover the secret to more velocity range and power of just a standard slingshot design. Speaking of which i just shot my SRv3 for my cousins 2 days ago and it hit 558.4ft! My furthest shot yet thanks to a hot day and slight breeze. It is true that the pulley idea will keep the bands tense and stretched further but it does not in my experience gain power distance or velocity. I built the v1, 2 and 3 and spent hundreds of hours researching the ideas. Im currently stuck with my current distance and plan on trying out flat bands for added velocity and range.

author

Really? I built another sling shot before this just to compare them. There's a slomo feature on my iPhone, so I put them both in slomo and the one I posted was traveling much faster. I wish I had some different types of stretchy things other then rubberbands. 558 feet is incredible, that's like almost two football fields. Did you notice that I took your advice and built this will no broken parts?

author

Yeah your build looks great and works great all while sticking with standard uncut/modified parts. Keep on this path and your mind will continue to think of better and better solutions to building. Not using broken parts makes building an extreme challenge so anytime you can pull something off like this it's a huge success. Keep on building great stuff man I really enjoy seeing it.

author

Killerk, test the range with some #64's or #117 bands tied together, so those of use without slingshot bands will have an idea of how powerful it is.

Thanks! What's wrong with the trigger? And the front sight doesn't break off because the rubber bands hits very low on it. Think of it this way, it's like a tree, the base is very strong but the farther up you go, the more it sways.

Nice gun!

Vid maybe?

author

Thanks! A vid will be out in the near future.

This is awesome looking and I like that.

This has a great concept, and I like that.

However, I would not say it is twice as powerful. Unless it is a ratchet slingshot. If it is a free flying slingshot, I have gotten 200 feet with the OSSR 2. Now for a ratchet slingshot, those are extreamly well preforming numbers.

Either way, the way it looks means that it is one of your best, almost in the class of the R700.

author

Thanks! I was saying that theoretically this gun is twice as powerful then the ones that just have all the rubber bands tied to the end of the gun. I thought I was going to get hate for the looks since the front of the barrel is a bit weird. Thanks a lot though!

author

Makes sense. The front looks weird but not particularly ugly.

Cool gun it kind of looks like my Goliath (I'd like to think that u used it as an inspiration or something lol) and it gets good range too wow

author

Thanks! This gun was actually built before you posted the Goliath, I like to build a gun then make adjustments and run test so I've had this gun for a week or so but I just now posted it.
