Introduction: The Kinno-2: a Semi-Automatic K'nex Gun

Picture of The Kinno-2: a Semi-Automatic K'nex Gun
Greetings fellow iblers!

Kinetic here with the second version of a gun that Innovanna and I have been working on for the better part of the summer: The Kinno-2!  

The Kinno-1 was a revolutionary gun based on a concept conceived by Innovanna over a year ago.  The idea was of a removable power source that could be used to fire off bullets by utilizing an extremely efficient "sling" firing method.  This power source functions by housing 8 pre-strung rubber bands, pulled tight and wound a cog that is held in place by a small ratchet.  This ratchet it what is referred to as the "master ratchet" because it has the most direct control of the cog (we call it the fly wheel, there are two: one in the magazine and one in the gun).  If the master ratchet is released, all the bands would fire off uncontrollably, ruining the semi automatic effect.  That is where the rest of the gun comes in.  There is another fly wheel on the gun that controlled by an escapement ratchet, a ratchet that will only allow the fly wheel to rotate a small amount with each trigger pull.  Once the band magazine is loaded into the gun, the fly wheel in the mag interlocks with the fly wheel in the gun.  Because they are now interlocked, the release of the master ratchet no longer sets off all of the rubber bands, but rather shifts control of them to the escapement ratchet, and thus the user has the ability to fire one band off with each trigger pull.  There is also a second magazine, the bullet magazine, that houses the gray connector bullets that this gun fires.  Every time a rubber band is set off, it catches the bullet, slinging it on its way while the band remains in the gun until the band magazine is removed.  

Sorry such a long and likely boring explanation, but I just wanted to let you know exactly what it is that you are going to be building.

So let's take a look at the pro's and cons shall we?


-Semi Automatic (very high rate of fire)!

-45 to 55 feet in range.

-8 (although I recommend 7) shots.

-Removable band magazine (power source) and removable bullet magazine (ammo source).

-Master ratchet now locks in place!

-Nearly unbreakable escapement ratchet.

-Clean design.


-Magazines (especially the band magazine) are rather piece consuming.

-Two magazines must be loaded for the gun to fire, not just one.

-The gun will fire upon release of the trigger, not upon the pull.

-One modified piece and some electrical tape required for the bullet magazine (other magazines can be used though).

Enjoy the video:

Special message:

This is going to be the my final K'nex gun.  I am in college now, and while it is an amazing experience, it requires a lot of time and effort.  However I now have access to tools and means of building far more complex than K'nex, and thus my possibilities have been greatly multiplied.  I will be back, but with creations far more advanced than anything you have seen thus far.  So keep an eye out!

So, for all you K'nexers out there, for the last time, Let's Get Building!


Step 1: The Handle

Picture of The Handle

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

1.  The handle.  Simple yet comfortable, this handle provides a solid connection between the shooter and his gun.  Also includes the trigger guard.
2.  The exterior plates of the handle.  Build these.
3.  The interior layer of the handle.  Notice the protruding white connector on one of the plates, highlighted by an image note.
4.  The center layer of the handle.  Take care to include all white rods, as they are what hold the handle together.
5.  Place an interior plate on top of one exterior plate as shown.
6.  Place the center layer as shown, so that the white rods  extend through both the exterior and interior layer.
7.  Place the second interior layer as shown, attaching it via a white rod as highlighted by image notes.
8.  Place the final plate as shown.  It may seem as if the handle will fall apart, but this will stop once attached to the rest of the gun.

You are done with the handle!  Move on the next step if you want to start building with the big boys!

Step 2: The Trigger Mechanism and Trigger Housing

Picture of The Trigger Mechanism and Trigger Housing

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

  This is the trigger mechanism.  It consists of a very strong two-part escapement ratchet, along with a cog that we call "the fly wheel".
2.  The external plates of the trigger mechanism housing.  Take care to include all the protruding blue rods, located on one plate.
3.  The internal plates of the trigger housing.  Notice the blue rod protruding from one plate.
4.  The center layer.  The mechanism consists of the fly wheel, the trigger, and the two parts of the escapement ratchet.
5.  Connect one of the internal plates to the external plates as shown.
6.  Add a black (or green) rod where shown.  Location is highlighted by image note.
7.  Attach the center layer.  
8.  Attach the final internal plate.
9.  Complete with the final external plate.
10.  Attach a small rubber band where shown.  Make adjustments depending on how smoothly the fly wheel rotates.
11.  Another view of the band placement.

You have completed the trigger mechanism!  The most difficult part of the build is behind you!  Let's move on to the band magazine release mechanism!

Step 3: The Band Magazine Release

Picture of The Band Magazine Release

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

 The magazine release mechanism.  A very simple, yet very effective little mechanism.
2.  The external plates of the release mechanism.  Notice that one has protruding rods while the other doesn't.
3.  The internal layer of the release mechanism.  Make two of each part shown.
4.  The center layer.  Prepare these pieces.
5.  Attach the two pieces of an internal layer as shown.
6.  Attach the center layer as shown.  The blue clip serves as a locking mechanism for the master ratchet.
7.  Attach the parts of the second internal layer.
8.  Attach the final external layer.  
9.  The parts that make up the lock itself.
10.  Put them together as shown.  
11.  Side view of the part you just made.
12.  Now insert the lock you just made into the housing as shown.
13.  Push the lock in.
14.  Place a doubled up small rubber band as shown.
15.  A side view of the band placement.

You have completed the Band Magazine Release!  Let us proceed to to the fake barrel...

Step 4: The Fake Barrel

Picture of The Fake Barrel

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.  

1.  The fake barrel itself.  A very simple build, the fake barrel does not actually serve to directly guide the bullet, hence the term "fake".
2.  The two external plates of the fake barrel.  Be sure to include the blue rods on one of the plates.
3.  The internal and center layers of the gun.  They are exactly the same, so don't worry about what they are called.
4.  Attach the internal layers as shown.
5.  Top view-just for further clarification.
6.  These parts make up the part that actually keeps the magazine in place.  Make 'em.
7.  Put them together as shown.
8.  Top view.
9.  Attach it to the rest of the fake barrel as shown.
10.  Attach the final external layer.

You are done with the fake barrel!  Now all we have to do is build the magazines!

Step 5: The Band Magazine (power Source)

Picture of The Band Magazine (power Source)

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

1.  The band magazine serves as a the source of power for the gun.  It has a capacity of 8 bands, although I use 7 because there is a chance that bands can snap if wound too tight.
2.  The external plates of the band magazine.  Take care to include the blue rods on one of the plates.
3.  The internal layers of the band magazine.  
4.  The center layer of the gun.  Notice the white rods protruding from the plate.
5.  Attach the internal layer to the external plate as shown.  One of the wheels is not attached to anything, and will be held in place by the center plate.
6.  Attach the center layer.  Includes the fly wheel.  This will hold the wheel mentioned earlier in place.
7.  This is the master ratchet.  It consists of two tan clips, a gray (or red) connector, and a white rod.
8.  Attach the second internal layer along with the master ratchet.  
9.  A closer view of the ratchet's placement.  Disregard the fact that the blue spacers are missing.  
10.  Attach the final external plate as shown.
11.  Attach a blue clip (or anything that will take up this space) where shown to reduce movement of the fly wheel.

You have completed the Band Magazine!  We will go over how to load it later, so let's move on to the bullet magazine...

Step 6: The Bullet Magazine

Picture of The Bullet Magazine

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

The bullet magazine.  Utilizes a unique internal pusher system, although it does require one modified part as well as some electrical tape to function correctly.    Its non-symmetrical layout will require to me label each layer differently, but I will be as clear as possible.
2.  The backplate of the bullet magazine.  Be sure to include the two protruding white rods.  
3.  The walls and magazine pusher.  Build 'em.
4.  These are the pusher guides.  If you can, use ball-joint sockets instead of one slot gray connectors.
5.  Gather these pieces.  Notice that the right part of the tan clip has been removed.  
6.  We are going to tie the band to the gray connector.  Start by threading the band through the hole in the middle of the connector.
7.  Bring the band around through the open part of the connector and thread it through as shown.
8.  Pull the band tight.
9.  Place the tan clip in the center hole of the connector as shown.
10.  Connect the magazine walls and place the magazine pusher as shown.
11.  Attach the pusher guides as shown.  If using ball-joint sockets, snap them around the white rods.
12.  Slide the piece made previously around the green rod as shown.
13.  Snap it around the other green rod so that the tan connector attaches to the lowest middle hole in the pusher.
14.  Gather the parts for the top of the magazine.
15.  Place the gray connectors with the black (or green) rods as shown.
16.  Place the outer part as shown.
17.  Lay the piece you just made over a strip of electrical tape as shown.
18.  Wrap electrical tape around to secure the pieces together.  Be sure to pull the tape tight.
19.  Attach the completed upper magazine to the rest of the magazine as shown.
20.  Gather these pieces.
21.  Attach them on the front.
22.  Attach them on the back as well.
23.  Loop rubber band around blue rods as shown, adjusting the tightness as needed.
24.  You may need to add a rubber band on the other side to compensate for the tension.
25.  If you aren't using ball-joint sockets you will have to secure the bottom of the guides with a rubber band.

Well, that one was more extensive than I had predicted, but pat yourself on the back because every component has been made.  Let's put the rest of the gun together now...

Step 7: Putting It All Together

Picture of Putting It All Together

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

 Obtain the handle and the trigger mechanism.  
2.  Connect them via the connection points shown here.
3.  As well as the connection points shown here.
4.  The combined handle and trigger mechanism should look like this.
5.  Now obtain the band magazine release.
6.  Attach it via the connection points shown here.
7.  The trigger mechanism and handle, combined with the band magazine release, should look like this.
8.  Now obtain the fake barrel.  
9.  Attach it via the connection points shown here.  
10.  This is what the final product should look like.
11.  Attach this rubber band to the trigger as shown.

Congrats, the gun is now complete!  We just have to go over loading and firing and you can start shooting this thing...

Step 8: Loading and Firing

Picture of Loading and Firing

Each number corresponds to each picture with respect to order of appearance.  Take time to read each explanation.

We will start with the band magazine.  Eight bands will fit on the mag, but they may begin to snap at that point.  For this reason, I recommend using seven.
2.  Loop your first band around the extruding green (or black) rod as shown.
3.  Pull the band over and around the two wheels in the front of the magazine, making sure that it is still hooked on the green rod as shown in step 2.
4.  Pull band all the way back and hook it on the fly wheel.
5.  For reliability reasons, make sure that the band hooks on the connector portion, not the rod portion.
6.  Rotate the fly wheel backwards (clockwise, from this view) until the ratchet clicks twice.
7.  Repeat steps 2-6 for the next six rubber bands.  You are done loading the band mag!
8.  Now we move on to the bullet magazine.  It holds eight gray connectors.
9.  Pull down the mag pusher by the tan clip.  Pull down enough to fit one gray connector in.
10.  Load one gray connector.
11.  Repeat steps 9 and 10 until you have loaded all 8 connectors.
12.  Place a green rod as shown to lock the magazine pusher in place.
13.  A view of the green rod's placement from the other side.
14.  You are done loading the bullet magazine!
15.  To load the band magazine, place the band magazine in the gun as shown.
16.  Top view.  Make sure the protruding part of the gun is between the two wheels.
17.  The magazine should be in this position.
18.  Push magazine down until it hits the magazine lock. 
19.  Give the magazine a final push so that it becomes locked in place. 
20.  Release the master ratchet and lock it in place.  Make sure that the band magazine is secure before doing this, or else your fly wheel will release all its bands simultaneously.
21.  The gun with the band magazine should look like this. 
22.  Now ready your bullet magazine.
23.  Insert the bullet magazine into the gun as shown.  Friction will hold it in place.
24.  Remove green rod to release magazine pusher and begin feeding bullets.
25.  Your gun is now loaded and armed. 

Congratulations!  You have made your very own Kinno-2!  Simply pull the trigger to fire.  Special thanks to Innovanna for the concept and for helping me with the design of this gun.  I'll be back soon with some all-new designs and creations!


MemoryFoam (author)2017-10-30

I don't have many metallic blue clips, is there any substitute for them? I can use broken / edited pieces if needed.

The Knex Inventor made it! (author)2016-06-04

Nice concept! I have always been interested in semi-auto mechanisms, so this one was a must-build. I didn't test ranges, but it probably would have gotten anywhere in between 30ft. and 40ft. The only problems were:

a. The magazine required a broken piece

b. The band magazine took a long time to load

Other than that, this is a great gun and concept! Thanks, Kinetic!

Thanks for the comment and for the photos! Its always awesome to see that. As a designer, I think that this gun's magazine and ratchet system have a lot of potential in other applications. The magazine because it introduces the idea that the use of rods in the structure can allow for internal pusher designs (definitely something to be built upon in the future), and the ratchet because it distributes directs the force directly towards the joints (that is, it induces no moment on the mechanism itself), making it capable of withstanding very high tensions. This definitely could be used in future slings. Just some ideas seeing that you've built it and are looking for ideas. I'll be keeping an eye on whay you come up with in the future.

Thanks again for the comment and constructive criticism. Think big!

You are welcome! Yes, this gun's concepts definitely have potential. Thanks for the ideas and the encouragement!

JonnyBGood (author)2012-12-20

This gun seemed very assault rifle-ish so I made it look a little more like an assault rifle. The first pic is the finished product the second is my kinno 2.

H1T4TCH1 (author)2012-10-26

What are the amazing guns at 2:30 and 2:40 ?

Raz1r Knex Bull3t (author)2012-10-11

I built the gun. It's awesome.

JonnyBGood (author)2012-10-09

Awesome gun Kinetic! I was working on something similar to this a little bit ago off a lego gun I found on youtube. I will definitly build this when I find time.

innovanna (author)2012-10-05

Here we go. This is it! This is everything we have wanted in this gun and you did it! Great job man. And if you ever have any ideas or concepts you wann try out id be glad to attempt to build them. My gun building has gotten alot better.

Sharir1701 (author)innovanna2012-10-08

dude, i would like to collab with you if either of you have a good idea. let me know...

innovanna (author)Sharir17012012-10-08

Umm ok im totally ok with that. Better guns and ideas come out if more people collab. Haha

Kinetic (author)innovanna2012-10-08

Couldn't have done it without you man. And if I come up with any ideas, I will be sure to draw them out and show them to you. You working on anything new by any chance?

innovanna (author)Kinetic2012-10-08

Ok ill take you up on that. And yes, i am. I got that pump action sling working beautifully. I used my own rubberband loading system, and used you kinetic rifle ammo loading mechanism. I made it smaller. But now im making it lok good. My gun building has gotten better, and i dont use mettalics anymore. So all of them look good. Im excited for the conteset sharir is hosting. I think ill do pretty good.

mettaurlover (author)2012-10-07

So far as the trigger is concerned-firing on release is only really a con on something inherently shotgun-like; on a rifle, for example, it could MASSIVELY increase accuracy since releasing a trigger requires much, much less force than pulling it, and can be a much more controlled action.

Sharir1701 (author)mettaurlover2012-10-08

that is very interesting. i will give it some thought and see what i can come up with.

Kinetic (author)mettaurlover2012-10-08

Yeah...I never really thought of it that way, although the point of this gun is really to get a lot of shots off in as short a period of time as possible. But given its range, accuracy does become a factor too. That is a very interesting point though, maybe such a function would be a good advancement in real sniper rifles in the future, so long as the shooter could still decide not to fire even after he has pulled the trigger.

Raz1r Knex Bull3t (author)2012-10-07

I absolutely love the magazine concept, I think I'll start using this idea in some of my guns. Hopefully I'll be able to find a way to rid the magazine of the broken piece, I have that broken piece due to past guns, but not to many people want that broken part. I was thinking I could take the idea and put it into a blue rod magazine.
Also, I want to see if you can post any creations from the more advanced equipment you'll be able to work with, because I want to be a mechanical engineer too and I'd love to see the stuff you can build. I hope I can build this next weekend, it will depend on homework.

Yeah, I think this magazine really does have some good potential. If you get rid of the entire upper part that requires the electrical tape, you can just use the gray connector that the broken piece attaches to as the pusher, because it does protrude into the magazine a bit.

And I will be posting my new creations here, although they will likely require advanced equipment to make. I'm also unsure as to when I will actually have access to the shop, it may not even be this year. If you want to be a mechanical engineer, just be prepared for all the mathematics that comes along with it. That is all you will do when you are in college. I love to design and build things, but I am not such a big fan of all the tedious calculations that come along with it. But, it's a dual-edged sword I guess, and if it means I can create things, I will by all means do it.

I think I'll customize my M4 magazine to be like this one, but it'll hold blue rods. I feel the same way about mechanical engineering, I know it requires a lot of math, but as long as I enjoy the job I guess. Best of wishes for college, look forward to talking with you in the future.

PotatoCoffee (author)2012-10-07

This really is great man! Thanks for posting! I may make it and add a stock when KIC is done. When I read Sharir's comment about you leaving I was like:
>Kills self<
>Reads your comment on out not leaving<
>Rises from the dead<

Kinetic (author)PotatoCoffee2012-10-08

Wow...what a series of events lol. I hope you do make it! What are you working on for KIC? Or is it a secret...?

PotatoCoffee (author)Kinetic2012-10-08

Well, Sharir1701 knows, in fact he knows pretty much about everything I make out of K'nex. Basicaly, it's V2 of my KSAR, or the concept is the same, the rest is secret.
This message will destruct in
Asta la vista!

Kinetic (author)2012-10-08

Lol and I thought this one would keep the masses happy for at least a little while. But I like the way you think! However blowbacks are not the wisest choice when it comes to K'nex guns, because it directs too much energy into a cosmetic feature, as opposed to the bullet itself. Fully automatics, however, are very possible, and I believe that this gun is a good predecessor to future full autos. But unfortunately, I am done with K'nex, so we will have to hope someone can see the possibilities this gun has to offer.

Raz1r Knex Bull3t (author)2012-10-07

You are asking for way too much. Knex can limit us to only a certain number of possibilities. This comment isn't supposed to be rude, it's just what your asking for is REALLY, REALLY hard to do. Although maybe someday we can achieve that goal.
BTW, I don't think he has the time to do that, Kinetic is off to college and he's going to be really busy. But, Kinetic will still comment on here, he just won't be able to post any knex projects due to school.

actually, from what i understand from my conversation with him, he stopped altogether. he will not be building with knex anymore at all, not just when he's at school.

mulletman6 (author)2012-10-05

Yay. Been waiting for this for ages. I'm going to build it tomorrow :)

Kinetic (author)mulletman62012-10-06

Sorry it took so long man, I've honestly only been able to do about two steps per week. Hope you love it!

mulletman6 (author)Kinetic2012-10-07

That's fine dude. I understand that you've been busy at college. I've built it, but have yet to try it out properly :)

Never, ever, feel rushed about posting something. We all are very busy sometimes in our lives, knex is not a main priority.

true dat lol.

Sharir1701 (author)2012-10-04

i have several things to say:

first of all and most importantly, NNNOOOOO! you are not leaving. that is all.

second, i like the video, very nice montage, perfect song for the occasion, nice.

third, i'm glad you posted this and i will be modding mine with some of the stuff here for sure.

fourth, the magazine is very nice. it's so funny that i was exactly working with a very similar magazine based on the same concept (your other bigger magazine, right?), just waiting for the right gun to add it to, instead of just posting it solo, which would have been a waste. i really like how you attached the pusher, i didn't think of that.

fifth, you are NOT leaving.

sixth, will you still be on the site and checking out and commenting on knex stuff? on the same subject, go check out my contest (obviously i realize you won't be participating, but still check it out tell me what you think). it's in a forum topic.

seventh, what better materials would those be?

eighth, why don't you have any BALLS ! ?

ninth, you are NOT leaving.

Kinetic (author)Sharir17012012-10-05

First of all, I am NOT leaving! I will be here, active as I can be. I apologize for my lack of presence over the past month; it has taken a lot of focus and effort to get into the swing of all things college, but I am getting the hang of it. This past month was by far the fastest month of my life.

Second, I'm glad you liked the video. I know it does seem a little corny, but I wanted to make a little sort of tribute to all the guns I have made, and I just couldn't use any other song for the occasion.

Third, I hope you are able to find some benefits to this gun. In the long run, maybe you can use some of its features to perfect your own.

Fourth, I am very proud of this magazine. Although It does use a broken part and electrical tape, the original version required no modded parts or exotic materials, and simply used the gray connector running along the pusher guides to push the bullets. That version could be used in a simpler gun, but this one has been modified to fit the Kinno-2. What does yours look like?

Fifth, you're right, I am not leaving XD

Sixth, I will still be looking at K'nex stuff, just not as frequently. I saw your contest, and although I only skimmed over it, I think it is a great idea, and, given the amount of entrants you already have, an effective idea as well. Keep it up!

Seventh, I plan on utilizing the school's machine shop and 3d printing machines to design and create real crossbows, and maybe, even full-fledged guns. As a freshman, however, it is hard to get access to this utilities, but I am taking steps to do so.

Eigth, ...

Ninth, You are correct sir!

Sharir1701 (author)Kinetic2012-10-05

i'm glad to hear you're not actually leaving, but you still won't be knexing anymore, right?

it is corny, but it's very nice. i enjoyed it very much. the lyrics of the song are a perfect fit, that's what i meant.

i'm not working on it anymore, actually, but i will add some of the stuff you have here, like i said. i will probably change my trigger mechanism, because it's not working out as well as i hoped from the beginning, and the fact that your's now has a lock for the band mag is an encouragement.

my magazine wasn't actually planned for the kinno, it doesn't work very well with the mechanism. it's very simple. it is very similar to your other magazine (the bigger, older one, you know what i'm talking about) in the way it's built, and has the same type of pusher. it has the 1 connector wide hole on both sides, where the rubber band goes. it's all 5 way connectors on the sides, and 4 way connectors at the top. your's is a hell of a lot better than mine, it's just i had the same (i'm assuming) thought involving your older magazine.

i think my contest will be less successful than it seems. i think the first few rounds will have about 5 or so entries, which is good, but it will fade, and also most of the people on the list are not actually going to be participating. quite a few said they won't be able to submit so much, but they still want to be updated, and might post a thing or two. it's only around 5 or so, like i said, that i think will be actively participating. oh well...

oh that sounds neat ! is the 3d printing material strong though? i thought it was some soft plastic or something. maybe a crossbow, but it would burn from the gun powder, wouldn't it? or do you mean mechanical guns, similar to the ones we make with knex? well that does sound very interesting. will you be posting some of the stuff you make? i would really love to see them...

you do get my BALLS ! reference right? otherwise it would just be weird lol.

Kinetic (author)Sharir17012012-10-06

No, I will not be K'nexing anymore.

Is there anything new that you are working on? I saw your S4, and I was very impressed. Anything else planned, or are you going to focus on monitoring the contest at the moment?

And I know what mag you're talking about now. The one that I used in the BTPA-7? What kind of ammo does yours hold? I actually had a top-loading version of this one, but that wouldn't work with this gun obviously. The cool thing was that it didn't require any broken pieces though.

Well even if you only get 5 entries, those are 5 likely innovative guns, given the nature of the contest. If it wasn't for TD's original contest, I wouldn't have come up with my slingshotgun or the KSP, both pretty big advances in my opinion. Every innovative gun posted is a step forward, and that is going to happen with your contest.

And there are several kinds of 3d printing. We have the small, design-only printers that used compacted powder to make small replicas of computer-designed objects. These are very weak and are intended to simply give one an idea of what the design will actually look like. Eventually, once all the kinks are worked out through testing with the design printer, we have larger, scarier machines that will cut and bend aluminum. With the strength that aluminum has to offer, I can make functioning prototypes of my designs. I already have plans for crossbow/guns that are, in essence, a combination of the guns we build and legitimate crossbows. This will set the foundation for crossbows that fire using turrets and other more advanced mechanisms. I do have one unfinished design for a legitimate gun, using gunpowder and everything, but I'm not sure when I'll have the opportunity to test that. And yes, these will be posted.

And no, I didn't get the BALLS! reference lol...

Sharir1701 (author)Kinetic2012-10-06

btw, i forgot to say earlier that my gun uses innovanna's trigger, which actually works better with your layout. my gun is very awesome. it's the best of both of your's combined plus a little personal touch from me.

Sharir1701 (author)Kinetic2012-10-06

too bad... : (

no, i'm mainly trying to perfect the S4 and then i will post it, but i don't get much done, since my new school (10th grade, first year in high school, yay...)(i'm also in the most demanding class there is) takes up a lot of my free time. i am primarily monitoring the contest then, yes, because that takes little time, relatively. i do have an idea for a new gun, but i honestly don't know when i'll get round to it. it's kind of hard to explain, so i don't think i'll do it at the moment. lets hope you'll be able to see soon lol.

yes, that's the one. i just never remember that name... BTPA-7... never mind. i guess your's is actually less based on that then. mine was based on the mag from your BTPA-7, but slimmed down for 1-slot connector ammo. i'll try to get a pic up to show you what i have. it's very simple, but it's definitely more reliable than your's (which i built btw, and it works very nicely, but it still is a little edgy...).
mine is top loading btw, it has a bullet stop (ceiling) and an internal pusher (duh...) and works very nice. the only bad thing about it is it's layout. i guess you could just make a slightly different mag well for it though... or i may change it a bit with what you demonstrated... idk

i'm glad you're optimistic. well, there is something in what you're saying, but then again, you're you... no one else is you. i hope i get at least one or two really good guns each round, but there's no promise for that.

that sounds really really exciting. is it legal for citizens to buy gunpowder where you live? or are you making your own? i'd be glad if you could somehow send me a copy of your gun design (the legit one). well, if it prints in aluminum, i guess there's no problem then. i'm really looking forward to see your advancements with those things. and who knows? maybe one day you'll actually wind up designing real guns and making a profit off it. good luck with that.

i hope you're kidding...
