About: Just an aging K'nex launcher builder

Mkay, sorry, but I still couldn't be bothered to get a full instructable. It's silly though that this is pretty easy for an experienced builder, so I got quite a few pics that should easily help you figure it out. Anyone is allowed to post it without permission as long as they obviously credit me, and a notification would be nice too.

Anyways, I'm warning you now that this gun uses a few broken pieces and has hideous range. You could modify the gun to accept a normal pin instead of the charging handle-like pin I made but I didn't bother trying to myself. The back sight was crudely thrown together as it's too large, as is the front sight really. It lacks a top rail (as if it was useful) but still has a bottom rail and can still use the generic forehandle. Lastly, it lacks a stock. Overall, I'm just hoping someone can build and modify this for me, then post it.

1. Whole gun. Looks purty, dun it?
2. Top of magazine, pointing out broken pieces. The front one is actually clipped down a little. If you really want, you could probably get away without these with some modifications that I didn't want to bother doing.
3. Here's the side ripped open and the handle area.
4. Another side view on the back.
5. A side open view on the front.
6. The inner side layer ripped off revealing the middle layers in the back.
7. And ditto for the front.
8. Finally, the inner and outer right side layers for the back.
9. And for the front.

I'll add notes where necessary.

    Built this. It’s okay. How does the fake barrel stay in place?

    I dislike the idea of the mag using broken pieces; I much liked the idea of the old one, with the locking blue piece.

    I much like the new barrel compared to the old, as well as the handle. Overall, the design is much sleeker, which is a plus, given your old one.

    Yeah, I really try to avoid broken pieces when possible, but I just happen to have a lot of broken oranges from building, so I figure it's not to uncommon for others to have them too. If I ever remake the gun again, I'll try to use only normal pieces.

    And thanks. I've always thought about improving it further, but I want it to be a big improvement.

    At the time I didn't have enough pieces for a stock. I may consider rebuilding this and adding one some time in the future.

    This is a very great gun. The only problem is that the band makes the pin fly out no matter where i put it. i put the green rod where you suggested it, but it still comes out.

    I was using my 3DS because it's easy to upload straight to facebook and then get on the computer to transfer it to ibles. I don't know where my other cameras are at. I'll try my iPhone next time.

    So the earlier pics were taken with your DSI? That explains the low resolution! But really please use a real camera or the IPhone with some sort of stand or tripod so the picture is less blurry and so we can zoom in to see fine details. If you had used a real camera or a good phone camera we might have been able to build the TBAG.

    I'm not an image noob, I know! Again, I used my 3DS's camera because it's easy to upload with. My digital camera is lost in the piles of junk my parents like to make while cleaning. But I just got an iPhone for my birthday which also makes uploading easier with so I'll start using that.

    But I will say one thing that has sort of become a motto for experienced builders: You're not doing us a favor by building our creations, we're doing you a favor by providing any instructions at all. Anywho, any forums I make are of weapons I don't plan on people building until I get instructions unless I clearly state that I have no intentions of making instructions myself. For example, the TBAG had a flaw in the back of the barrel. I didn't want more people complaining about what didn't work so I didn't get any more pics of it.

    And I don't mean that yours is a 50*50 bit pic it's just not good enough to make the gun from.

    I know we aren't doing you a favor by building your creations It's just nice to be able to build them even if the have a flaw. It keeps us tested and on our toes to do so. It's just good practice. But if you made a 50*50 bit picture of a knex gun you don't get enough detail to make it. It's just that simple. And about the piles of stuff I have the same problems with the cleaning but they put it in paper bags but my parents keep the 1000$ DSLR downstairs in a cabinet in the living room. I suppose you have a place where you keep your old game-boys and other electronic you rarely use so just put the camera there when you find it. If not just put the camera on a window sill in your room with the charger or in your closet for storage and put your electronic charging station in your bath room (that's what I do) And by piles do you mean 5 ft mounds or short ones?
