K'NEX Gun: Rate of Fire (+ Internal Pics and Videos)

Introduction: K'NEX Gun: Rate of Fire (+ Internal Pics and Videos)

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.
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."

Features:
  • 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

    Even though I haven't built it. I am going to go on a big gun building spree when I destroy my ball machine

    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 "pusher" 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.

    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.

    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.

    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.

    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.

    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.

    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.
    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.

    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.
