Picture of Knex Hybrid Interchangeable Shield, Crossbow, Gun
This is an idea I had a while back. I finally got around to making it. This knex hybrid is a shield, crossbow and gun. The gun and crossbow are interchangeable. You can shoot both of them from behind the shield.

The crossbow is actually more like a sling shot. It does not have a trigger. The gun however has a true trigger and also a side loading slot, so you don't have to reach in front of the shield to load.

Parts list:


Gray rods: 19
Red rods : 3
yellow rods: 60 (Can be any length I had more yellow)
blue rods :1
white rods :14
green rods :20


blue connectors: 8
yellow connectors: 11
green connector: 60
red connectors: 11
light gray: 5
orange: 7
gray clip: 6
blue clip: 3

4 blue spacers
2 gray spacers
2 black hinge piece and one complete hinge
3 green flexi

ok, now normally i don't say this, but you might want to put a block trigger on the gun. with the true trigger your hand is completely exposed, and a block trigger should be easier to pull FOR THIS GUN.
 or you could have sear system or a lever ontop like iac heavy cannon 
have some common sence, wear gloves, like me lol
Well if someone would use this in war. (Which I don't think anyone would) If your hand gets hit even if you are wearing gloves, you would be out.
no what i mean is that he was having trouble cocking it so wear gloves for grip
That would just make it harder.
i thought you only posated your best ibles and how did you get so much knex
What are you talking about?? I do post my best ibles. And I get my knex off ebay.
this doesnt look anywhere near your best
What are you talking about?? I didn't make this.
o.o .O. wow......
well think about it, the shield should protect you, but it's no use if your hand is out side of it. with the block trigger it can be pulled from the top of the gun, so your hand stays inside the shield the entire time.
how can anyone fit behind the shield withought getting shot?
or he could make the trigger upside down?
yeah yeah, it makes sense, im just saying...
or he could just make a smaller shield below the big one to protect the hands.

to change between the gun and crossbow mabey make use of those connectors that look like yellows but connect to make a right angle

Nice idea. Just a nice idea, nothing more. Perhaps it would be better if the shield was bigger, but not so piece consuming. I rate a 4.0

interesting, but if this only covers your hand, what are you going to do with the rest of your body? PS 4*
Hmm.. not bad.. okay gun, and a great idea. 4 stars

I'm glad you liked it. What would make this a 5 star in your opinion?
It would be sweet if it was a bit more piece efficent (the shield) and the weapons a bit more powerful. it also looks a bit troublesome to use. But thats just me, and im veyr picky.
