Introduction: K'NEX Gun: Ripper

Picture of K'NEX Gun: Ripper

The coolest fictional gun from the Call of Duty series would have to be, in my opinion, the Ripper (EvoPro III). With the ability to toggle between the SMG and the AR world, and that incredible body, whats not to like? Making a functional K'NEX replica, however was not easy. In the first place, there were no dimensions for me to base my replica off of. In the second place, the distance between the magazine and the firing mechanism is unrealistically small. So I decided to take the same approach that I did with my Magpul PDR, and make a breach loading gun out of it. You can also look at this gun as the close range cousin of my RBLTR.

Before I go any further, I will make a disclaimer here and point out that this is technically not a replica. I did my best to duplicate the Ripper, but almost from the start, this gun was created for fun, and nothing else.

The one downfall of this gun was the range. I got 60 ft. max out of it, using two new #117 bands. This is caused by the fact that it has a 5 1/2 - 6 in. pin pull length, that could not have been enhanced without extending the stock. I didn't want to do this, so I left it "as is."


  • Average range (for a full-size): 60 ft. max
  • Breach loading mech
  • True trigger
  • Permanent foregrip
  • Comfortable grip set
  • Good, close range, iron sights
  • Great, long range, flip up holo-sight
  • Shoots yellow rods, blue rods, and white rods
  • Sturdy body
  • EZ-load system (just push the round into the chamber and lock it into the bullet-lock)
  • 4+ different ways of holding it
  • Short overall body (great for indoor K'NEX wars)

LOL, sneaking a fast one? I don't know what you are talking about. >.>

I'm glad you like it, it is a pretty poor representation of the "real" one, but it was a start. =D Thanks man, glad you like it!

The looks on this thing . . . . . . . . are amazing, I love it!

Finally! Some one like me who loves futuristic guns! Thanks man! Where have you been?

Say what? Someone say something about futuristic K'nex guns?

Well, I suppose I just took you for granted... I know you have always been my main supporter, especially of my futuristic guns... You and DarkOwlProductions that is...

I know... just teasing... =P

your welcome, I have been so busy, with homework from my ap classes and just with life in general, I tested for my second degree blackbelt the other day, and I am finally taking a break from life for a day or two. But, I do have something big planned for my next post. MG

Ah, I can relate. I just got a job, and the only reason why I have been able to post is because I already had all of the pictures taken. I haven worked on my Stoner 63 in days.

As you can see, I have been pretty busy lately,(last post was 1 month ago) but am on this site once again. My machine gun is annoying the heck out of me. Everything is just so delicate and precise and frustrating. Still haven't decided on a good enough mech to rely upon, just to much friction with the ones previous to the current model. I don't know if you ever saw me and myOmy's machine gun. It is on his account in his forum topics. Tell me whatcha think.

I absolutely love the looks of this gun! It looks futuristic and deadly at the same time! I think you did a great job of replicating the gun, especially since you didn't have documentation to work from, which means you had to build this without any dimensions. You did a great job!

Thanks man, glad you like it! Don't forget to vfavorite and vote!

This looks great! I really like the body and the sights :-)

Thanks man! Don't forget to vote for my entries!

Kona-chan (author)2014-08-01

No, but at the end of the day, it would be kinda pointless... LOL

realism bro

Thanks man! What have you been up to, and can we expect to see that ARX-160 any time soon?

P.S. Don't forget to vote!

I've been building several things: a gun with a working drum magazine, a gun with a horizontal magazine, a semi automatic gun using a new concept, and a few other things. As for the ARX-160, I haven't done much about it, because I'm the president of procrastination. ;) I really need to focus on one thing at a time. Maybe I'll go work on the ARX-160 today. I'll vote for this gun.

Huh, I'd love to see those... Think you could get me some pics, of, like, all of them? =D

I'll try to do it today. A lot of them are half broken, though. If all the guns I had were completely broken, I could build something huge. Once, I built I_Am_Canadian's heavy mag-fed crossbow, and I still had pieces to spare.

myOmy (author)2014-07-26

dude. . . . That looks sick.

You think so! That makes 4 of us. =D

Don't forget to vote!

sick as in a good kind of sick, although it is a little contradictory to use sick as a good thing, looking back on this comment it is very unnessesary to ramble, and yet here I am rambling on again. XD, I did vote

Ah, this I see! Thanks again man!

you ever see my entry to the contest?

Kona-chan (author)2014-07-30


LOL, thanks man! Don't forget to vote for it!

dr. richtofen (author)2014-07-28

It definitely isn't the prettiest gun, and nothing new. But the grips are cool.

Well, you and I have two very different tastes. I would assume that you find both the H&K G11 and the Calico M9___ series ugly? Yeah, well, those are the type of guns that I like most. The unusual. Thanks again man, and don't forget to vote!

Yeah, I don't really like the looks of those two guns, but eh, each to their own.
Didn't vote for it, because I'm not gonna vote just because I like the grips. And there are way better entries anyway.

Yeah, well, everybody likes different things. =D

akshat21045 (author)2014-07-26

This. Is. Awesome.

Yes! Finally! Someone who thinks this gun looks good! Thanks man! Don't forget to vote!

It's the best looking gun of yours I've ever seen (Err, second best. First being your SL8)! I guess I like weird looking guns!


Lucas The Boss (author)2014-07-29

Wow it's ugly and awesome great job

In my opinion, this is the best looking gun that I have ever built... Maybe it takes second place to my AK-12... maybe. I think it looks boss. But I can respect your opinion. =D Thanks man!

When I say it is ugly as dirt I mean that it is awesome I mean come on you dident really think that I thought ugly was bad I mean since when was ugly a bad thing. That applies to everything but girls

JonnyBGood (author)2014-07-29

Well, well, well. Looks like you've finally built a futuristic looking knex gun! I haven't seen the gun in game yet but it does look cool! I'm not entirely sure what's going on in the rear of this gun, but I suspect its where the mag would go? Anyway good job!

didexo (author)2014-07-27

This has got to be the ugliest gun I've ever seen, but nevertheless good build.

Really? Well, in my opinion, this is the best looking gun I have ever built... but to each his own. Thanks man, don't forget to vote!
