Knex Gun: Thunderbolt Hand Cannon + Internals.




Introduction: Knex Gun: Thunderbolt Hand Cannon + Internals.

About: I enjoy archery, knives, and building weapons. I used to build with K'nex.

Hey guys, I have another gun for you! This one is a futuristic K'nex pistol. It features a synthetic futuristic body, thumbhole grip, unique trigger, and it's a single shot. It seems to like shooting a grey clip and green rod the best, followed by white rods. The trigger blocks the pin very far back, and the mech only holds one #117 band. Still, it shoots very well. Next time you see these pieces they will probably be in a free flying slingshot, or a bullpup rail pin. (Why has nobody come up with one where the rail pin is pulled all the way back into the stock?! I might have to fix that myself.)

This is the perfect gun if you prefer to exclaim, "Oh, SICK!" when you see it rather then, "What a elegant design!"

That's right, it's jammed with features and looks to appeal to the COD: AW and Destiny crowd, and no one else. I don't fit in that category, and I just think it looks weird. You may not.


Fairly comfortable.

Looks... interesting?

Shoots 50+ feet.

Very sturdy. (8 layers, 9 in some spots.)

Long pin pull.

OK trigger pull.


Piece consuming for what it is.

Shoots all rods except green.

Shoots several connector+rod combos.

Nice sights.

Three layer trigger that feels like it came off of a TR.

So what do you think? Tell me in the comments below, and feel free to criticize your hearts out. I going to keep posting, expect more! And what do you think of the indoor pictures? Not too shabby, huh? Let's get to the internals.

Do not dry fire this gun! It can break the bullet lock.

Step 1: Internals

Here are the internals. Ask me if you have problems. (With the gun, not with anything else.) Have fun with your new gun. Unless, of course, you just wanted to see how it worked. That's OK too.

    Nice. :)

    I'm sorry that it doesn't shoot that well. It was not built for shooting, that was just one of the features that came out of it.

    But thanks for building my design!

    no problem buddy, but still, maybe you should note that it's not meant for dry fire because it doesnt like dryfiring
    and it packs a real punch bro I'm using larger type oddammo
    also sneakpeak for my new tactical pistol


    OK, yeah, the pin will hit the bullet lock and mess it up. I'll add that to the description.

    That new pistol looks nice! I'll be sure to check it out when it's posted/

    never said it messed up anything it just snaps off the connectors on the pin

    LOL, well when I dry fired it, it would mess up the bullet lock, so thats why I put it down like that.

    So, this took a bit longer than I wanted, but I finally got around to tinkering with this gun.
    I took out the shooting mech, and just fiddled around with the general design.
    It is two connectors longer than your gun, but that was kind of needed for a comfortable hand guard.
    The handle is a little shorter than I'd like, but with the foregrip, it's comfortable enough.
    It has a fake removable magazine in the top, that loads like some guns from the Borderlands series. When you open the lid, the magazine gets pushed up a bit, for easier removal.

    All in all, I like it. It has an odd look, but I really like how you did the thumbhole.

    This almost looks like a smaller Competitor V variant lol. Awesome design!

    Yup, that's what I thought. It wasn't an attempt at a copy, but it turned out that way. Thanks!

    I know, how it goes great minds think alike sometimes. Just like I copied a lot of the functional features of another pump bolt action gun in zip3 with no idea that it was similar in every
