Hello again. Here I am with my 5th entry to the "Toy Rods and Connecters Contest," a K'NEX gun I named "Rate of Fire" (ROF). I built this gun for two reasons:
1) I wanted a gun that I could run as many rounds through it as I wanted without worrying about it jamming, and
2) I wanted a gun with a great rate of fire = how many bullets can leave the barrel per-second.
What got me started on a ROF gun was Sharir1701's REMPAR. Seeing him shoot off all of those in that amount of time shocked me, and I was like "dad-gum-it, that is awesome!"

With all of that said, I present to you my K'NEX gun: Rate of Fire. It kinda reminds me of a mix of a Magpul PDR and Sharir1701's S1. It has a rate of fire that can empty one mag (7 bullets) in less than 3 seconds. I have not done a full range test yet, but it probably gets at least 40 ft, if not 60 - 70 ft. This is technically a second attempt at my "The TUB."

  • Great rate of fire: 2.3 bullets per second (7 rounds per 2 seconds)
  • Good range: at least 40 ft.
  • Comfortable
  • Cheek rest (see pic #5)
  • Easy to charge, even with two bands (I only have one in the pics)
  • Nice body (IMO)
  • Nice looking sights

I love this gun. Boom. Mind. Blown.
Even though I haven't built it. I am going to go on a big gun building spree when I destroy my ball machine
It shoots a dark grey, one slot, connecter with a green rod attached.
This gun is quite bad.
And yet it got featured, 95% of K'NEXers like it, and it works great.
Dont listen to him, he is just your usual f**k head member off KI!
I know, I'm not listening to him. <a href="https://www.instructables.com/community/Some-Videos-I-think-You-Guys-Should-See/" rel="nofollow">Careful bro</a> (see video #4 on that link), before you hurt your self. XD
Because 95% of people don't understand why its bad. And it got featured because you took pretty pictures, not because of how good it is.
No, because 95% of people aren't jealous that it got featured, and it did not get featured because I took pretty pictures, it got featured because somebody at 'ibles liked it.
Looks good. Can you explain to me the magazine some more? Like, how are the rods advanced after each round?
Thanks man. Well, the rubber bands push the &quot;pusher&quot; up and this pushes each bullet into a position to fire it. I don't know if I am making my self clear...
That makes sense. The firing and reloading of these guns is fascinating and I'd love to see a straight-up detail explaining how it works.
I could provide some pics, and a video...
It would help those of us that aren't quite as experienced. I think a separate Instructable just explaining the mechanics is something that would be really beneficial. <br /> <br />There's very basic K'NEX guns, and some very advanced ones; but I don't see any documentation explaining how they work. You pro gun-builders are on another level and maybe take these complexities for granted. I'd love to see a detailed Step-by-Step that covers triggers, magazines, reloading, firing mechanism, bi/tripods, elastic types, and all other manner of accessories. <br /> <br />I'll throw down a 1-year membership and a freshly designed digital patch to the first who can make a comprehensive Step-by-Step showing me exactly how K'NEX gun mechanics work using the elements I listed as a guide.

Has the method and style of construction not changed since that was written?
The basic mechanisms and triggers outlined in that instructable have not changed in the slightest. There may be new variations and new components that have been invented since then like turrets, but the core concept of a pin striking the ammo, or the ammo being slingshotted out of a gun have not changed since the inception of knex guns in 2006. Neither has the classic magazine mechanism where ammo gets pushed up into the barrel changed, there's just been many different ways people construct that same push-up magazine, either to accommodate different ammo types or for cosmetic reasons. Hoppers are kind of going out of style though to be honest. <br> <br>If I were to look at recent gun designs barring some bizarre new experimental concept gun, most would either feature a tube barrel, or a square barrel in the case of magazine fed guns. Some mag fed guns even have a tube barrel, thanks to the advent of iPod Killer's sniper in 2007. <br> <br>The short version: There may be many different new variants on magazines, triggers, and mechanisms, but the way each of them work at their core is still exactly the same.
So, you're saying that there's not room for an updated Instructable detailing how K'NEX guns work? I disagree. Though the information might be similar, I think the sophistication of the weapons I've seen has increased and there is a need to share basic information for new readers. <br /> <br />I think things can always be presented again in a fresh clear way and there's no harm in a new approach on that topic, especially if it's by a different author. <br />Luckily, 2 other members have already risen to that challenge.
I agree there's been lots of improvement and change since that guide has been posted, and weapons have gotten much more advanced. However, I think this guide would give newcomers a good understanding on how mechanisms work on the most basic level, despite it's 6 year age. <br> <br>I also agree though that a new, updated guide could be in order, preferably one with physics explaining what makes a more powerful build and maybe insight as to why the best guns are the most reliable and powerful.
I think I will split up what you said into two categories, and make them two different 'ibes. The first one will be all about the gun its self, anything from different kids of guns to their particular mechs. The second being different accessories, grenade launchers, sights, things of that sort. TAD and I are planning on working on it together.
I will add another video, and some pics of the internals, but I am not sure if I want to to another instructable just to do it.
I'll definitely take you up on that offer. :D Have been working on it for a while now.
So let me get this straight, all of the thing you mentioned in one epic ible'?! Hmmmm that would be a lot of work.
A rod with a rubberband pushing it up constantly pushes up a new round into firing position once the current round has been fired.
Exactly. What he said.
I have to disagree too. A bolt handle is faster than a plain pin only because it gives you easier access to pulling the pin. However, then you have your hand oddly placed and to the average shooter, this won't make you as fast nor accurate just because it's not natural. If you need a little more science, then chances are that the offset of the bolt will make you start pulling your gun to the left a little never keeping consistent aim. A pump is optimal. And if you don't like current pump action designs, then by all means, make your own. And seeing how you're willing to throw range out the window (very fair if you have a high RoF) then try to make it a repeating shotgun so you can easily overwhelm people. But that's just my two cents. Your gun is just fine.
IMO Knexsayer is still the best pump action out there.
That's what she said.
Looks amazingly smooth!
Thanks bro, could you give my stuff some votes in the contest?
Looks alright. I'm not sure yet, got to make a gun for KILLERK's knex war, but I aiming at shooting larger ammo. Just so I can find it in the grass easier. I may use your design though.
Are you gonna go to K'NEX War 2013? Sounds so awesome... Go ahead and use my design, and I'd love to see it when it is finished. Sounds awesome.
Well I may use some design off of it. I'm trying to go to war with a semi-automatic gun, but I'm still deciding. It's harder than I though to build a war gun that you can see yourself using.
Yeah, that sounds tough.
Yep, still thinking about it. Going to try to build something else here, and unfortunately I've thrown in the towel on Thunderbolt. Just to much stuff going on. I may post a blueprint though if you want to see what tree I was barking up.
What?!?! You are giving up on the Thunderbolt! No! Why? I would love to see blueprints/internal pictures!
Well I gave up because after a few tries and no success I'd really rather focus on something that works. I spent well over a week using all my free time on this thing so I just feel that I needed to move on. Here's the blue print though I think it would work given the right knowledge and time.
Ah, I can understand that. Thanks for the blue print, I read it, and you did a great job explaining it.
Thanks! I thought it might be confusing, and to be perfectly honest I wasn't even sure if it was true bolt action either. If anything it's kind of like a mag loaded breach rifle. kinda anyway =P
Yeah, its kinda just what people want to call it that matters. =D
Thanks man. =D
Np =D
Thanks bro, that is a nice comment. =D
Yep. One of the best guns on the site in my opinion.
I know I'm butting into the conversation again, but I kind of have to agree with Blue Mullet in almost all of her statements. The NAR is a better gun in the fact that it can go a lot farther than this, just by nature of the mechanism; although, this may reload a bit faster, it doesn't go nearly as far, so it all depends on what you're looking for.<br> <br> As for sights, they may not be needed, but if you have an accurate gun, they are very helpful. I know that you haven't built a TR before, but they can probably reload faster than this. The reason being: you only have to pull a firing pin back, but with a bolt, you have to pull it forward <em>and back</em> before you are ready to pull the trigger and fire. Turrets and Bolt Actions tend to be great with sights and accuracy; any gun that's being fired as if it were a single shot has nothing jamming up against it, and it also has nothing effecting its accuracy.<br> <br> I don't think that this is one of your comfiest guns, exactly. It's a good, sturdy stock, but your shoulder is pretty much resting on a hard rectangle of plastic. &nbsp;The handle, I think, seems a bit too slanted to be at its comfiest.<br> <br> My opinions, and I think Blue Mullet's are very founded: BM said she feels the design is better; this implies that she's using judgement based on what she's heard, seen, and maybe even knows; that judgement isn't necessarily unfounded just because she hasn't built it. &nbsp;I have built turret rifles, and I can tell you that this gun may very well have a slower rate of fire than a TR. &nbsp;I can easily make a gun have a faster rate of firing by pulling the pin faster.<br> <br> Also, pump actions are faster, because they are more natural; a pump is located in a position where most people naturally grip a rifle in the first place, so pulling that area back and forth might be a bit easier than this. &nbsp;Truly, what the rate of fire comes down to is how fast you are cocking, sliding, or doing whatever to reload the weapon.<br> <br> All that being said, I really like the gun. &nbsp;It looks cool and functions pretty well, but BM is pretty much right in all those areas. &nbsp;I'm sorry if I sound mean, but seeing that this is your second gun featured in like a week, it kind of saddens me. &nbsp;Don't get me wrong: you deserve to be featured, too, but maybe not this excessively.<br> <br> I hope this doesn't offend you, but I feel like the same people are being featured over and over. &nbsp;I have never seen certain users that I would say have equal talent to yours be featured. &nbsp;People like Didexo, Raikou-San, and others have gone through like thirty five brilliant instructables each, and have never been featured, merely because the moderators of this site haven't seen their work. &nbsp;<br> <br> After typing all that, I'd like to have the liberty of saying that I voted. :3 &nbsp;I really don't know when I'm going to end this comment, but it's probably a good idea to stop typing now, so I will.
XD, Let me make my message as short as possible. =D <br> <br>When it comes to the first paragraph, I agree. It really does depend on what you are looking for. As to the NAR, I disagree. From what I have heard, it only gets 40 ft. max, not the claimed 100 ft. <br> <br>As to the second paragraph, I am just going to reiterate, sights really don't work, which is something I have found to be true. It may be different in other peoples opinions, but I don't think that they work. <br> <br>Third paragraph: to each his own... <br> <br>Fourth paragraph: ...meh, it really does not matter. <br> <br>Fifth paragraph: I might agree. <br> <br>Lastly, I can see that it might be galling for some people to see my featured twice within a short period of time, but I cannot help that. There are lots of people, including you and Blue Mullet, who are better builders than me, but it comes down to which editor likes who's stuff... not who is the best builder. <br> <br>Thanks for the long message, and the complements, it is good to hear from you. =D
