Introduction: K'NEX Gun: Defiance (R5) (Build)

Picture of K'NEX Gun: Defiance (R5) (Build)
Ever since I can remember, bolt action guns have entranced me. From how they look to how they operate, everything about them has really attracted me. So, in order to "give a tribute" to this wonderful system originally designed by TheDunkis, I constructed the Declaration, the parent weapon to this gun the Defiance. On the whole, the Declaration did not go over so well, and admittedly, it had some flaws. Over all, the biggest objection to the Declaration was that it was (or so people believed) just a modded ZKAR. I still hold that this was not the case, but that is a subject for another time.

This gun, the Defiance, is one of the best bolt action guns that I have yet seen. I has abilities that many other bolt action guns don't have, and is versatile enough that you could modify it to you liking without much fear of damaging the performance. With ranges exceeding 60 ft. (easily), this gun is durable and sturdy enough to "protect" you thorough many a K'NEX war.

- Bolt action
- New trigger mech
- New bullet transfer system mech
- Great grip/handle
- Nice, usable, sights
- New magazine set up, with magazine breach
- New bolt and pin set up (adapted from the Zaktangle)
- Extra magazine goes into the stock
- Easier to unjam than ANY other bolt action gun
- Very comfortable setup

Alright, lets move on to the first step.

Step 1: Main Body

This step is probably going to be one of the easiest, as it is the least elaborate. Build the left panel and then add the blue rods as seen in the pics.

Step 2: Internals - Part #1

We are now going to work on the internals, mech, etc. Don't forget to read the image notes, and if you need any help, drop me a note.

Step 3: The Bolt

So in this step you will be building the bolt, adapted from the Zaktangle. You can mod it to your own preferences, and indeed I suggest you do this, as it will make the Defiance more your own.

Step 4: Internals - Part #2

So in this step, you will be finishing off the internals. Follow the pics and image notes (if there are any) as seen.

Step 5: The Grip

I am sorry that I did not take the handle all the way apart, but this is something that you should mod to your liking, as my handle is hefty and piece consuming. And yes, the broken parts are needed if you are going to build this exact handle.

Step 6: Right-side Panel and Body Additions

This step is pretty self-explanatory, just do and build what you see in the pics.

Step 7: Magazine

Again, I am kinda sorry that I did not take apart the magazine to its full extent, but it is really pretty easy to build, just ask me any questions if you have any. Keep the image notes in mind while building.

Step 8: Extras and Finishing Up

All you will be doing in this step is adding the side panels and rubber bands n' stuff. If you are running low (or if you are completely out) of green rods, just skip most of these pics and look at the pics that are about the rubber bands. Again, keep the image notes in mind while building.

Thanks for building the Defiance, I would love pics, comments and reviews on how the gun worked. Thanks again for your support, and I hope you enjoy the build.

akshat21045 made it! (author)2014-05-17

Sorry for being late! :D

I made the entire version with all my new pieces.

Sweet! Nice Job! Do you still like it?

Of course I like it. And the holes in my calendar I made with it. LOL

XD, nice.

Oh yeah, there is however a problem in the gun. On the firing pin, there is gray one slot connector, which breaks after heavy use. But I guess I can sacrifice one piece for an awesome gun.

Huh, funny that you had problems with that. I never did, and I shot mine quite a bit.

JonnyBGood (author)2014-05-15

Well I just removed something from my build list! This is My Defiance! 4 hours of building later and I will tell you that this gun isn't beginner friendly but it is pretty comfortable and shoots well. I'm still occasionally breaking the chambering rod but its not to frequent. The one major visible thing I changed was I added a mag lock. Nothing against your friction one but I don't like friction in general (unless its in a Vann DeGraff generator) so I just added a hinged segment as shown in the third picture.
Overall, I like it! I would've liked more pictures to help me along faster but the final product is definitely worth the time.

akshat21045 (author)JonnyBGood2014-05-18

I must add that mag lock on mine. It would be very useful!

Glad you like it bro! Yeah, I am sure I could have done better with the 'ible, but I can be a terribly impatient person. What range are you getting?

40ft easily, I haven't maxed it out yet, mainly due to me still fiddling with it. I haven't really got it functioning the as smooth as I want it to yet either so its a work in progress.
I will say though this gun is my first bolt action I built off this site and its interesting that it doesn't use any moving parts. I was surprised.

Great! Yeah, each gun takes about 10 min. to 1 hour to really finish, after having been built.

akshat21045 (author)2014-05-04

I made it again, and this time it works epicly! My favourite gun yet, hands down. I think I might use it in the war this year (if I make it, I guess). Do you want the newer pics? I have them if you want!

I'd love more pics!

Whoops! Never saw this comment. Put some pics tomorrow! :P

My trigger would work better if you hinged it the other way so it was pushing on the hinge instead of pulling on it. Plus you'd get way more pin draw.

Wow you're mature. I gave you advice that will make it legitimately better and that's your reply.

Ahhhhhhh, how did I know you would take it that way. I probably should have asked if you had seen either movie, then you might have got what I was trying to say, but it is no matter.

Now, as to your advice, I thank you for it. All the same, if I had used your mech, two things would then be the case.

First off, if I had used your mech, then the mech would not have been original to me, thus sort of taking away from the fact that this gun is a brand new design.

Secondly, if I were to set up the mech as you propose, it would necessitate that the trigger be farther away from the grip, thus causing you to force your finger to reach farther, and reducing the comfort that this setup provides. Admittedly, there might be ways around this, but not many would have the sturdy set up my mech provides.

Again, I thank you for your advice, but you could have put it more courteously, nevertheless, its all good.

Why make it worse for the sake of originality? And you can make plenty of variations on it, so that it will be comfortable and still work. I've done that with my guns.

Worse is it?

Well, gotta say, TheRacker does have a point there. Your reply could be more mature....

Dude he was just trying to give you advice. Maybe you should try it and see how it goes!

First off, this gun has already been taken apart. Secondly, I don't see why you are all huffy, 'cause, and this is a fact, I did not even say anything to TheRacker until just a few minutes ago... Also, why is it that when I rebuff KIers, you come to their rescue? It is kinda silly, IMO, but NVM.

hunter999 (author)2014-02-02

Wow! Thats one action packed gun! I like how you can fit an extra mag into the stock and how easy it is to unjam the gun.

Great as always Red! :-)

Knex Lego Maniac (author)2014-02-02

I just noticed the gun is able to carry a spare mag in the stock witch is a nice feature. If I ever made a mag gun that would be a must for sure.

zKnar (author)2014-01-25

was this a joke gun

TheAwesomestDude (author)zKnar2014-01-26

looks like a hatah to me, joined jan 25th one comment ever! No subs or anything, just hating on this sweet gun

Oh, just ignore Zak, he is still sore from his last "tizzy." I am pretty sure that he does not like any other bolt action gun except for his, which is fine, all the same, I wish he would keep his discourteous comments to himself. Nevertheless, he is entitled to his opinion, no matter how wrong he may be. After all, TheAwesomestDude, you and I know what good guns are.

Oh that's zak haha lol I didn't know that was him that's to funny lol XD

Yup, I am pretty sure that that is ZakS. Yeah, I know right? Ironed. Completely ironed.

dr. richtofen (author)zKnar2014-01-28

Oh please, get off your throne of arrogance. You may have had success with your ZKAR's etc., but this does not give you a reason to have this holier-than-thou attitude you're having.

JonnyBGood (author)2014-01-25

I get your name =D. Indeed this is a defiance against the past of the Declaration. Regardless, good job with the gun! You brought back my favorite feature from the Declaration, the rounded handle. Definitely deserves a spot on my build list!

Yeah, you seem to be the only person who "read into it." Good job! XD

I am glad you like it, I hope to get some pics when you are done...?

Well thanks! And yes I will take pictures when I get around to building it.


I got a long build list but I'll definitely get pictures when I'm done.

Yeah, I can relate, although I tend to not built other peoples stuff too often, I just always seem to have stuff that I want to create. If I had enough K'NEX to build other peoles stuff and my own I would probably do so.

akshat21045 made it! (author)2014-01-29

Just trying the new 'I Made it!' comment. So, I'll act as if I'm making it the first time.

Hi Red! I made this gun and changed the way you told me. It has an awesome range (especially the breach loaded round)! I hope that you like the pics I am sending you!

I saw that button too, so I am excited to use it! Thanks man, I am glad that you built and enjoyed the gun!

gabriel180 (author)2014-01-31

Hey red, love it :D

Hey man, whats up?

I am glad you like it. Are you gonna build it?

Element Force (author)2014-01-30

I really like the pin guid

Thanks man, but, you know, the rest of the gun is there too. =D

Knex Lego Maniac (author)2014-01-27

like that fact this gun has a removable mag. I like that it is bolt action. Like the ball bearing trigger concept which has been used before I know but just saying. Not a fan of cut parts as always but the gun looks fun and like a creative use of pieces. Keep it up Red. A few less cut parts would impress me even more :P

Thanks man, I'm glad you like it. As to broken pieces, I guess I agree, but to me, this turned out how I wanted it, so I am not to worried about broken pieces. All the same, thanks man! =D
