Introduction: K'nex Gun: Comeback

Picture of K'nex Gun: Comeback

Heyo, so even though I've been active here I haven't been posting very many guns. So, I though I'd make up for it by posting this great new gun I've been working on called "Comeback"

I started on this gun by trying to modify the SMRI that Red and TD are working on, but I wasn't to fond of it. I'm not sure why though. Anyways, I started working on this brand new gun to show everyone that I'm still building. So without further ado, to the gun.

Gun Info:

I'd just like to start off by saying this gun was very out of my comfort zone because if its size, even though its not that big. But anyways, this was a very difficult to get to work, because of the bullet transfer system. What bullet transfer system you may ask? Is this just another stupid single shot guns Didexo? Well actually no, this has a horizontal mag under the barrel and it works great. I tried to get everything jammed into these gun to get it to work great. How 'bout them pro's and con's? [Ranges haven't been tested]

-Horizontal magazine
-Comfortable stock/handle
-Realistic sights
-Decent pin draw back
-Non-Band trigger
-Easy to use/load
-Overall it looks good? Wouldn't ya say?
-No broken pieces, that was a tough one

-Magazine only holds 3 blue rounds, but you could lengthen the barrel I guess
-Front grip is a little weak, easy fix though
-It's hard to fix, on the rare occasion is jams, you have to take off every layer

Well that just about sums it up for this gun, tell me what you think!

Awesome looking gun! Favorited :-)

I kind of wish more storage was possible with the tubular mags :(

I built a horizontal mag with perpendicular mounting that's pretty reliable but the bolt only let it get around 30 feet, far less than something like this. Good job man!

didexo (author)Dreamwave2015-04-15

Yes it is quite a shame. Did you post it?

Dreamwave (author)didexo2015-04-15

the instructible I made with mech in the title is it, there are even more pictures in the comments section of that and the other gun

First off, this looks really nice, that was my first impression. Secondly, I like how it operates using a tubular / horizontal magazine. I am glad you are "back with us!"

Thanks Red! See what I meant by how it doesn't look like the SMRI? Ha, glad to be back :p

Yup, and I am sure we are all glad to have you back. Yeah, XD, it looks nothing like the SMRI. Do you want some pics of my most recent version? I just took them last night.

Yeah, that'd be great.

Alright, well, here they are. You will notice that they pictures aren't very informative as they were taken in haste. Have any questions?

Looks like Red's been busy with Valentines Day preparations! Nah I'm just kidding, looks nice!

I am afraid I don't understand what you mean by: "Looks like Red's been busy with Valentines Day preparations!" Are you talking about the teddy bear? Glad you think it looks nice. =D

I think that's what he meant.

I meant that you were building k'nex instead of preparing for valentines lol. nvm. its already over!

XD, valentines day is my birthday, I don't do the preparations, my family does!

Nope, no questions. Just wanted to see the updated version out of curiosity. Like the teddy bear :p

O.K. sweet. Yeah, the teddy bear was just laying there on the carpet so I picked it up and put it on the gun (at the suggestion of my little sis). =D

Thanks Red! See what I meant by "It doesn't look like the SMRI at all"? :p.

Hmmm, this looks just awesome. It looks too good actually! I would like to know something more about the transfer mech (I've always tried to make a horizontal mag, but it always fails :P)

didexo (author)akshat210452014-02-16

It actually not that complex, I can post some internals if you'd like?

akshat21045 (author)didexo2014-02-16

Yes, I would!

War pig (author)2014-02-13

That looks cool!!!!

didexo (author)War pig2014-02-16

Thanks man!

hunter999 (author)2014-02-15

Looks pretty sweet! Good job! =D

didexo (author)hunter9992014-02-15

Thanks man!

hunter999 (author)didexo2014-02-15

No problem! =D

rathemighty (author)2014-02-13

Dude, it's not coming back. Your K'nex Gun found somebody else. I'm sorry, dude.

didexo (author)rathemighty2014-02-14

But, we had something special...

rathemighty (author)didexo2014-02-14

I know, it hurts, but it's time to move on

didexo (author)rathemighty2014-02-14

I guess, but on Valentines day too :(

rathemighty (author)didexo2014-02-14

This has been awesome

This looks and sounds awesome. My only criticism is 6 layers?? C'mon thats not symmetric. I prefer 7.

didexo (author)FlyingFish102014-02-14

First, thanks Fish! But with seven layers, I felt it would be to bulky :/

dr. richtofen (author)2014-02-13

That is really cool! It's great that you came up with a horizontal magazine mech that doesn't use broken pieces. I'll have to get used to its looks, but it looks pretty smooth.

Great job!

didexo (author)dr. richtofen2014-02-13

Thanks, actually the mech isn't that complicated to use without broken pieces. Also, yeah I get it, the front grip bothers me. I'll probably change it.

didexo (author)2014-02-13

Thanks Blue! It is because of the 6th layer :p

JonnyBGood (author)2014-02-13

Looks great! Really like that horizontal magazine and how compact the entire gun is in general.

didexo (author)2014-02-13

Hope ya enjoy! Drop a comment below (or below, I don't know how this comment system works :p).
