Introduction: T.B.A.R (Thunder Bolt Assault Rifle)

Picture of T.B.A.R (Thunder Bolt Assault Rifle)

Due to many requests I am posting the TBAR or Thunder Bolt Assault rifle.

This rifle is just packed with special features. Some new and innovative and some old. First off, it is actually two guns in one. A 16 shot gun with removable clip, and a single shot sling shot that can reach ranges of 100-120 feet. The 12 shot gun reaches ranges of 45-50 feet and has some mighty power behind it. Oh, and both guns are fired from the true trigger in front of the handle.

So this is my assault rifle. The features:
Two guns it one and both are fired from one true trigger.
It has a textured butt for combat.
One of the guns has a 16 round removable clip for large ammo.
The other gun is a single shot slingshot that can shoot oner 100 feet easy.
And it uses a new trigger system that can fire both guns itself.

As you may know this had a rail in the slidshow, but that got taken apart before I made the instructions. If you want to build it from the pictures, here is the link to the slideshow.

Woo-Hoo! I've been wanting to make this gun for a long time now, but previously lacked the white connectors necessary to build it. Very nice gun! I haven't gotten a chance to completely test it out yet, but when I do, I might post a review of it. Thanks for the awesome gun, Killer~SafeCracker! Favorited and Subscribed. :)

OMG!!! im the 3000th viewer!! :D

I know this might be kind of weird, but how big is the barrel? Because I dislike the guns with A barrel shell and 3 layers of barrel orange connectors.
which is what most big guns are made of. Just in case u don't understand what im saying (because i'm confusing) go to Oblivitus and look at his rifle the Z35 or something because I made that and the ammo doesn't get hit by the firing pin since the ammo moves sideways in the barrel, "dodging" the firing pin making it not shoot.

Oblivitus (author)Pizzapie5002010-04-17

You built the chamber incorrectly.

Pizzapie500 (author)Oblivitus2010-04-18

Really? I even built it twice and it doesn't work.

Oblivitus (author)Pizzapie5002010-04-18

Then you built it wrong twice. You're the first one to tell me that they had that problem.

~KnexBuild~ (author)Oblivitus2011-12-15

I built your Z35 and it was awesome.

I think I get what your saying. There is not that kind of barrel on it. The ram goes through the real barrel, and right into the clip. Since the ram shoots through the clip there is not that problem.

K thanks I'm gonna make it.

Great, let me now how it works out.

I'm on step nine i'll tell u when i'm done.

make the semi auto part pump action, and this is going to my shelf as a keeper.

knextremist (author)2011-07-13

i made an internal mag push and it works great!!!! By the way this gun is amazing.

inergy (author)2011-02-26

Wow, great gun! My shot against some bricks, and it split my gray connector right in half. Then, the slingshot broke my tan clip. That is power.

Cheezpaper (author)2010-10-16

Pic 4 - are those green things the broken white rods that was on the items list at the beginning?

And if so, what length do I have to cut them?

knextremist (author)2010-08-24

my sling gun bullet wont disconnect from the trigger and i know i have it hooked on right so plz help

Pizzapie500 (author)2009-10-19

Why did you put that thing in the front?

I think it looks better.

plz write back as quick as possible how do you build the thing on the front and how do you attach it plz write back (what i mean by the thing on the front is the black fake barrel with the red light on the front)

Pizzapie500 (author)knextremist2010-08-13

I don't know how to... But that doesn't help and it isn't a light, it's a knex piece

knextremist (author)Pizzapie5002010-08-15

lioneatr (author)DJ Radio2009-11-23

It was a joke...........................

LOL, How do you spot these things??

Here is another one that I just spotted on your TBUAR!




I saw AJ's knex gun review had 1337 views, Your TBAP had 1337 views, and my OSSR had 2009 views.  All of them screenshotted.  And I also took a screenshot of Fungus Amungus's forum topic counter when he had 666 topics.

I have seen some instructables and what not at odd view numbers. I just don't screenshoot them.

Hiyadudez (author)DJ Radio2009-11-21

Here is another one! This is kinda creepy because I spotted this on his TBUAR right after I read your comment...

Vynash (author)DJ Radio2009-11-20

LOL you spotted that on my OB too!

DJ Radio (author)Vynash2009-11-20

I should have taken a screenshot loolz.

Vynash (author)DJ Radio2009-11-20

LOL photoshop it up :-p

Pizzapie500 (author)2009-10-19

What's a good rifle that has a good range (35ft+) good accuracy and good ROF?

DJ Radio (author)Pizzapie5002009-10-28

ZKAR v2 has what you are looking for.  However, don't try to fire it at 1 per second, the bolt will most likely break at that speed (It did for me).
