Introduction: Zip3 Pump-Bolt-Action K'nex Gun Preview

Picture of Zip3 Pump-Bolt-Action K'nex Gun Preview

It's offical the Zip series is my most popular knex gun series with Zip2 accumulating about 850 views. So when it comes to designing the next patriarch of my gun family I wanted to aim big, not so much size wise but performance and I definitely hit the mark. This is my most innovative and efficient knex gun I've built so far, featuring: removable preloadable magazines, pump operated bolt action, an extra magazine in the stock, and 40-60ft of range with two rubberbands.Well some other stats of interest:
Appearance is big and bold.
Easy and smooth bolt action.
40-60 feet range.
War worthy.
Can't complain everything works really well.
Three cut rods per magazine. My bad, but not to terrible.
Pump isn't very comfy, but it works well.
Cannot be dry fired.
Uses more pieces than Zip2.
Feel free to ask questions and thanks for looking at my latest Zip3!I will post this gun after Buzzsaw so please stay tuned for more pictures and updates.

Update 6/26/14
Well I have added internals of the latest version of Zip3. The first picture mainly shows the pump assembly and where the extensions to the ram rod go. The second picture shows the magazine in the gun. It shows the rods that attach the pump to the ram rod are right about the magazine, which also allows the gun to be 5 layers thick. The 25 picture is of the chambering mechanism which makes the gun as good as it is.

Go to this link for a video of Zip3

Haha, sweet job bro. You used my idea of this and made it better. Good job man! The only problem I had with mine was getting it to chamber correctly. Other than that, your's seems to work great.

Wow. I had no idea someone already tried this. Mine chambers correctly most of the time, but when it does jam up its pretty easy to fix.
Its as simple as removing the magazine and firing the gun. Overall though it's cool to see you already had this idea and how somewhat similar they are to each other. They both even store a spare mag in the stock XD!

Haha, yep. Great minds think alike! ; )

Indeed they do.

How are the instructions coming along? And the update?

megustatrains (author)2014-04-25

woah this is awesome must build in place of zip2!!!!

JonnyBGood (author)megustatrains2014-04-27

I would highly recommend it! Zip3 beats the Zip2 at everything but rate of fire (because Zip2 could always get a second round out faster due to the double barrel.)

Zip3 is also my best gun thus far. Instructions will be coming out maybe may-ish? I will be out of school then so i'll have time on my hands to post the largest gun I have ever created.... so far.

JonnyBGood (author)JonnyBGood2014-12-04

No offense taken man! I know I procrastinate really bad. I just need to do every gun like competitor V minus the problem. preview and post the next day. I will have an update here this weekend with internals. I won't miss that date because I already started taking pictures.

akshat21045 (author)JonnyBGood2014-12-04

Reading this comment and laughing... May-ish? (No offence man)

JonnyBGood (author)megustatrains2014-04-28

Also I was just thinking... How was Zip2?

Lucas The Boss (author)2014-09-11

Man I got a lot more knex ( got over a thousand peices for $15 at a yard sell) when are you posting instructions?

Sweet deal man! When am I posting instructions? hmmmm.... Good question. I currently am collaborating with the red book of westmarch on a assault rifle right now and I have some creative urge to build an X-29 AR. So maybe in a week or two? Depends on homework and some other factors. I'll keep it in mind that you want some instructions and I'll try to get them up sometime soonish. I'll contact ya u when I start making instructions.

Sounds good I am helping doc penguin on his sniper and creating a new pump mech (I think you will be impressed) but I'm not in any hurry so take your time

Awesome and more awesome. I love pump action so I can't wait to see what you've come up with. Zip3 has my strongest pump mech so far (if you're used to using it anyway, bit of a learners curb apparently) but for Zip4 I think I'm going to borrow some of the layout of Rempar because that seems to be one of the strongest pump action guns.
But yeah, can't wait to see what you come up with, and maybe I'll use your mech or build the gun myself!

oodalumps (author)2014-02-26

Does it use a zkar bolt mechanism?

Does "Cannot be dry fired" mean that the pin breaks? From the pictures, it looks like you could make a very short barrel extension in front of the pin to cover the dead space in front of it.

JonnyBGood (author)oodalumps2014-02-26

I'm not quite sure I get what you mean with the zkar like comment. I will say though that it can't be dry fired due too the top chambering mech. You can dry fire it if you want to, but you will deffinitly break a green connector. I did....Lol. I'll get you some internals so you can see how it works.

myOmy (author)JonnyBGood2014-07-18

you still got internal pics for me? Mabye?

JonnyBGood (author)myOmy2014-07-18

Dude this is still in one piece! I haven't even considered breaking down this gun yet. Its my piece de resistance!
Anyway I forgot to touch the upload ible on my phone so the internals hadn't loaded, my bad.

So, now they're up, and if you need more you know where to find me. This gun will be posted... eventually after I perfect it.

This comment is going to sound really rude, so please don't take it that way, but you do realize that not every bolt action gun uses the ZKAR setup, right?

Haha, when you think about it, this is the exact same concept of this I had a while back. He just perfected it. : ) (Hopefully the link works.)

Wait, are you talking to me? Oh, XD, NVM. You are correct and I completely forgot about how you accomplished this. Good job!

Haha, it's cool man. Most people didn't even notice it. : P

No, its not cool. If that is the case (and I hope its not), that is sad, 'cause your gun was boss. One of my favorites of all time. In fact, if I have not favorited it yet, I am going to do it now.

Haha! Thanks bro! If I eventually can get time away from all my high school work and such, hopefully I can post some more projects. Hopefully innovative ones, because I find for me that building functioning model guns not that big of a challenge. Whereas if you build a gun that isn't supposed to look like anything in real life, just a gun that's innovative, you're not restricted to a certain shape and function. So, maybe this spring break if I'm not too busy I can hatch an idea and work on it. : )

No problem. =D I really do hope to see you posting again, you build great stuff.

Thanks man. : D

I was implying nothing, only asking. I haven't been keeping up with Knex guns, so I haven't seen a bolt mech other than Zak's.

O.K., cool, I get you.

Ghasteqs (author)2014-06-07

Looks great! Shame that the pump sticks out of the gun's front a little; I guess the muzzle could be made longer, but then that could look iffy, and it would need more cut rods.

JonnyBGood (author)Ghasteqs2014-06-07

Well thanks! The pump a cctually doesn't stick out the front though. I designed room for your thumb there so the pump can be pulled back easier with more elastic strain.

Ghasteqs (author)JonnyBGood2014-06-07

Ah I see it now lol

JonnyBGood (author)Ghasteqs2014-06-07

Good! Lol... Beleive it or not I haven't posted this gun yet due to constant changes I've been making. This version was about 4 changes ago. Here's what Zip3 looks like currently. Its slightly longer and now has a larger, stronger, and more comfortable pump!

hunter999 (author)2014-03-15

Looking at the vid, this gun is pretty sweet! I like the mag, are you going to post instructions at all??

Also, it kind of reminds me of the Nerf Retaliator.

Spectacular job! :-)

JonnyBGood (author)hunter9992014-03-15

Of course I will be posting this. Its my favorite gun that I ever built! (Not to mention the longest) Expect a post in about a week or so.

Kona-chan (author)2014-02-28

what do you mean with, "dry fired" ?

JonnyBGood (author)Kona-chan2014-02-28

Fired without being loaded or without ammo.

Kona-chan (author)JonnyBGood2014-03-06

what's the use of that xD

JonnyBGood (author)Kona-chan2014-03-06

Beleive it or not I do that a lot. (the broken green connector proves it) But I dry fire during testing and overall just to get comfortable using the gun. I also dry fire to test if the trigger is working correctly because you don't want to start when the trigger isn't locking properly (granted that hasn't been an issue with this gun).

nerfrocketeer (author)2014-02-27

Cool man! This looks great!

JonnyBGood (author)nerfrocketeer2014-02-27

Thanks! I have a video of it now too.

nerfrocketeer (author)JonnyBGood2014-02-28

Ok, I'll check it out!

JonnyBGood (author)nerfrocketeer2014-02-28

So, what do you think?

nerfrocketeer (author)JonnyBGood2014-03-02

The video's pretty good man! I left a comment there as well! I like how the window light. Looks like a target when youre test firing!

JonnyBGood (author)nerfrocketeer2014-03-02

Yeah that was unintentional, but it looks okay so I kept it. I figure it was better to have to much light than not enough. Glad you liked it though!

nerfrocketeer (author)JonnyBGood2014-03-03

I think it looks cool! ;) Glad to hear you talking. I'll probably post a video like that myself soon, but for Nerf and the NK3AE.

JonnyBGood (author)nerfrocketeer2014-03-04

Sounds good. I'll be waiting to see it then!

nerfrocketeer (author)JonnyBGood2014-03-06


Lucas The Boss (author)2014-02-28

Hey this looks amazing I'm glad you improved all the things I suggested to bad I won't be able to build it

Zombiekiller-93 (author)2014-02-26

I prefer Zip2 to this one in my opnion. How's the Competitor IV going, can't wait to see my PM-63 hinge grip being used in something different.
