doofenshmirtz (author)2010-12-30

how far does it shoot? can it peirce a can fron about 4 feet away? if so, I'd class it as powerful. anyway it looks good and is easy to make as I started an hour ago and I'm already on step 4, part 1

fartnitro (author)2009-11-24

i modded, it has an aiming system, or laser sight (with lights!) or a bayonet. I'll post!

Oblivitus (author)DJ Radio2008-10-30

I made a more powerful, 25 shot version, although it has the capacity to hold 50 shots.

TedWard{} (author)2009-09-05

this gun makes not f*cking sense. i've followed all the steps and yet there seems to be a huge part of the mechanism missing. i can't even see where the bullets are surposed to come out! Plz can you show in more detail how the gun fires. i expect your phone will have charged up by NOW! lol :}

knexaddicted (author)2009-08-16

on pic 1 i ont get how 2 put the green connecters on

make it the same on both sides

knex shooter (author)2009-07-26

omg i cant fire it and it dunt click

Ok check to make sure that both the gears and the trigger are all attached to the right spots like in the instructions and then also make sure you have a rubberband pulling the trigger forward.If you look at the last step it will show exactly where to put the rubberband although it doesnt really matter as long as its pulling the trigger forward.

i no i have got elastic band pulling trigger forward thats fine but the mechanic bit im disapointed ... first of all i used yellow cogs :( i found 1 red one .. does it matter ... secound i think triggers on prop not two sure coz i put that red cog on front bit and the trigger is out of line with the red cog and doesnt touch it

ok it would be better to have to red cogs but since you only have one just put that one in front which is where you load the rubberband and put the yellow cog in the back and it should work fine.

i had the same problem, so having extra pieces i just took pliers and pinched off all the yellow tabs from the cog XD

Raz1r Knex Bull3t (author)2009-05-20

i love the gun i built it i actually can fire the gun like a machine gun.


post what there is nothing to post all you have to do is keep pressing the trigger really fast ordering to fire it like a machine gun
