Introduction: Knex Semi Auto Vector (instructions)

Picture of Knex Semi Auto Vector (instructions)

Finally!!!! This is my very, long awaited knex semi auto vector, with instructions. this is my 2nd entry for the Hurricane lasers contest, known as HLC. i know you guys have been waiting for so long, but now, here it is. I've built this gun because I've seen and made many generic pin guns, which fire single shot. i wanted to step the game up, so i made a semi auto gun. this gun has many pros, but unfortunately some MAJOR cons, too.

-great looks and feel
-semi auto 
-top rails for attachments
-it actually shoots 
-real working mag with internal pusher
-forward grip
-real iron sights (adjustable and removable)
-red dot sight which actually works
-holographic sight which actually works
-excels in close quarters combat

-very hard to pull the trigger
-doesn't shoot far (average is 15 ft)
-many cut pieces
-only used in close quarters combat

I uploaded a video showing you how the mech works here
Anyways, have fun building!!!!

This is sick but took me like 2 hours to make the stock XD I'm so slow

:) the stock is kinda complicated imo

FireFighter112 (author)2013-08-10

Looks very cool!

charlie-on-our-6 (author)2013-03-12

Yes indeed. Getahammerandachisel!!

Its a dialect of german, but it is a language spoken by few. These people are the mysterious, the exotic... The CODawesomians.

Sadly i gave up in fruatration : (

This looks aesthetically perfect. The semi auto mech is interesting, although I don't see how it could shoot at any range over 10ft.

CODawesome (author)~Aeronous~2012-09-17

Ik it can't shoot far cuz the firing pin doesn't move back far enough, so it generates less power

PotatoCoffee (author)2012-08-23

This looks good!

CODawesome (author)PotatoCoffee2012-09-08

thanks!! im still working on an mg36 from mw3, but the drum mag doesnt work. i might finish it in the next 3 weeks.

PotatoCoffee (author)CODawesome2012-09-08

Check out the "Vortus" drum mag, maybe you could add that! =)

Johnhall44 (author)2012-08-16

I might just build this sometime....

CODawesome (author)2012-08-11

Once I tried to upload a video of
Me shooting the gun and how the mech works, but it didn't work. There was some 'HTTP Error' which I don't understand. I took the pictures of the gun with my iPod, along with videos, but the videos won't upload. CAN ANYBODY TELL ME HOW TO FIX THIS?????

if you haven't, try uploading the videos to youtube (if you want a copy on your computer, you can always download a small mp4 file from youtube) through your computer or even directly through your ipod. i find it best to upload through my ipod and then download a copy to my pc. sometimes while transferring the files as they are from the ipod to the pc, the ipod generates huge files. uploading from ipod and then downloading an mp4 also solves that and makes a file about 1/5 of the size on the ipod without losing any quality at all.

CODawesome (author)Sharir17012012-08-12

i tried a different way; i posted a link of the video on youtube, and it worked!

Having the same problem with my pics

Mine doesn't work!

CODawesome (author)~Meme~2012-08-11

You mean it doesn't shoot, or the trigger doesn't move back to the original place? If the trigger doesn't return to the front, try pushing the back of the trigger forward. If it doesn't shoot, either you built it wrong (near the trigger area or the mag well) or you need more stretchy bands.

~Meme~ (author)CODawesome2012-08-11

The orange trigger keeps snapping.It doesn't fire nor does the trigger work

CODawesome (author)~Meme~2012-08-11

For the firing pin, don't stretch the band too far

~Meme~ (author)CODawesome2012-08-11

I've stretched it lightly. Also i'm having troubles with the mag. Im starting to think I should rebuild it.

AUG-5OM3 (author)2012-08-11

Sweet will try and build it tonight.

~Meme~ (author)2012-08-10

Thank you, thank you thank you!!!

CuddlesMcT (author)2012-08-10
