Introduction: Bullpup K'NEX Gun: Quarrel (R6)

Picture of Bullpup K'NEX Gun: Quarrel (R6)

For the longest time, Bullpup rifles have been a "passion" of mine. From their inherently long barrels, magazine setup, and grip positions, Bullpups are guns awesome. Sadly, many of the advantages (if not all) of real Bullpups are wasted on K'NEX guns (TheRacker talks about this here: All the same, Bullpup guns are fun to mess around with, fun to build, fun to shoot. What more could you ask for?

My original Quarrel (nick-named "Vengeance"), loaded the magazine in the top of the gun, and had room behind the grip for an extra magazine. This version does not load the mag into the top of the receiver, nor does it have a space for an extra magazine behind the grip - because that is where your primary (loaded) magazine will go.

- Bullpup mech, based off of the Reliable
- Comfortable grip
- SUPER sturdy
- Great pin-pull
- Nice sights
- Good range: at a "flat angle" 40 - 50 ft., at a 45 degree angle 70 - 80 ft.
- Easy configuration (you could remove the stock entirely and make it a SMG/carbine)

While a Bullpup setup is nice for slingshot guns, it is rather useless for a "simple pin" gun, and the amount of pieces and the length of the gun overall defeats the purpose of a K'NEX gun.

Video and internals will be up soon!

Enjoy, and tell me what you think!

Probably the weirdest bullpup rifle I have ever seen but it looks good. I myself will be making a bullpup rifle in June and I will also post instructions for it.

Thanks man, I'm glad you like it. Sounds good, can't wait to see yours. What's it gonna be?

Well I could tell you Red but that would be too easy. You have to wait and see, besides I like to surprise people and subscribers with my skills and my amazing instructions. But I have nearly finished the Dragunov and KAP-40 reviews ready for May.

Sounds good. =D

Actually make that July as I 'am posting instructions for a shotgun in June and bullpup is rifle is a old one that no one made instructions for.

Very nice! Not as complex as I originally thought it was but nonetheless interesting! I'm going to have to build a bullpup now... =P

Yeah, it isn't as complex, but that is what makes it nice. =D Dude, your build list is huge, you might want to work on it one gun at a time. XD

Yeah, I do... so many good guns so little time...=D

Heh heh, +1!


Just an idea, ( I just tried and failed this weekend ) How about a bolt action bullpup? It would be perfect, because when the chambering rod pushes the round forward it would get more distance from the firing pin giving it more range. Just a idea I thought you might be interested in.

I actually built this idea already, but it's so ugly even for my standards and it doesn't work correctly due to pin not hitting the round (too long body but I can't shorten it due to mag location) so it'll disappear, never to be seen most failures do. lol

ranting again, I'll take pictures of mine if your interested in trying to build one of your own.

I'd love pictures, but I probably won't try that project out for a while, I have a Mauser SP66 right now, and I am contemplating a semi-auto next... Not sure how it will turn out...

Well if you pull off a semi-auto I'll be first in line to build it! I'll also post some pictures here when I get home. They'll probably be posted here as to not insult your orangeboard, and everyone's eyes! lol.

Sounds good bro! I can't wait to see your pics, and I hope that my SA will turn out. =D

Well I hope your SA will turn out too! Anyway I took my bolt action bullpup apart, it offended my eyes too much (seriously it was that bad). I may try it again but I'm working on another project, Project Mohawk. A horizontal magazine that loads the yellow rods vertically ( so the gun is looking quite large ) It's one of those crazy ideas I recently had. Crazy ideas like this have led to my building of Springbreaker and Buzzsaw so since crazy to me seems to translate to cool and even mind blowing ( Buzzsaw ) I'll build it and see what comes together.

Nice gun! Nice chalk heart too. Did you draw it? Haha.

I'm beginning to recognize that arrangement of cobbles.

Nope, I'm not to big into chalk hearts, I myself prefer chalk Unicorns. You know how it is.

Yeah, no kidding. =D

Ah, I see... Did Docta R get you into this new form of art?

Nice gun I have never built a bullpup, would you have a suggestion on one I could build to get a feel for the mech because I don't have near enough pieces to build this one.
Over all in my opinion this gun is a great gun

Thankee kindly. You could build the BAR, but if I gauge the amount of pieces you have correctly, you won't have enough. To be honest, bullpups take a lot of pieces, so I am not sure what you could build.

I have more than what I have put into my previous guns but I just don't have near enough to build your gun, thanks for the suggestion I'm going to consider building. You are the second person who has recomended this gun to me so I am more than likely going to build

If you want to make a bullpup, try the B.A.R. by K'nexBuild. It is worth a build!

Very nice Red, this has great looks. :D

Thankee. =D

No problem! How have you been lately? :-) (its been a while, so I though I'd ask.)

FlyingFish10 (author)2014-04-23

I would switch your first picture (the .gif) cause it doesn't appear full size in the thumbnail

Done. Thanks for the suggestion!

No problem bro

Are you not going to credit k'nextremist? this gun looks exactly the same!

Well, I could give him "credit" but I hold the view that if the internals are different, not much was copied. At least, that is how it works in real life. In other words, the Dimaco C8 looks a lot like the Colt M4, but no infringement on rights was made. Likewise the vz58 looks a lot like the AKM / AK-47, but no rights were infringed upon, so there was no problems created. All that matters is the internals. My internals cannot be the same, as mine shoots out of a mag, his didn't.

Wait am I stupid? Yeahhh I am. Sorry. K'nextremist's gun's shape was inspired by one of YOUR guns! So that means that basically you don't exactly need to credit him! omg that's so funny

No, no, no, you're fine! Its all good... Wait... Sarcasam? Heh heh, NVM.

no sarcasm!! I'm just dumb!

Forget it, its all good. =D

I see no need. Bullpups tend to ollow this generic body.

Yes, and no. Yes, bullpups do have the magazine behind the grip (heh heh), but that is about all this gun has in common with any other bullpup gun. The only reason this shape seems common is because I posted my RBBR, then knextremist "copied" the main form from that gun, and I took his copy and modded it.

Ah ok. I read Fish's comment so I got it.

dr. richtofen (author)2014-04-25

Eh, I don't like how it looks, and like The Racker said in that topic, bullpups are kinda pointless in knex. I understand that that kind of mech is fun to mess to around with, but I don't like the execution in this gun. It just looks kinda ugly to me.

Meh, to each his own I guess. I think it turned out really well, but I agree, bullpups are kinda pointless (I said this in the description). NVM, thanks again. =D
