Knex Full Auto Gun Prototype(UPDATED 8/13)) by KnexFreak360
I have finished a fully automatic K'nex gun today. It is a prototype and not the best, but it is a good start and i am hoping for it to become an excellent working gun with some modifications. It does have a few flaws in it's design but like i said it is a prototype. My main concern is the fire rate it is so fast the bullets shoot out like a shotgun instead of a true full auto gun. I am sure this can be fixed and i will do my best to get the final version of the gun up as soon as possible. Now to the pros and cons.

Pros
  • Full auto
  • Small/Compact
  • Not a terrible amount of pieces
  • 6 round magazine
Cons
  • Shoots like a shotgun
  • Prototype

******UPDATED V.2******
Ok i just finished v.2 and thanks to everyone for their ideas and support. In v.2 i have increased the magazine capacity to 15 from 6, even less pieces now, new handle and magazine design. I also learned if you wish to have more power and add more rubber bands you get the (shotgun) effect instead of the full auto.

if only we could slow this down a little bit...

i could try to make a friction mechanism, but it would corrupt pistol size.

Yea i i think this idea might have to be abandoned because of how it works, if you put a friction mech in this it would kill the range because you getting rid of the energy from the bullet so yea.

Fred the evil puppet says: Oct 31, 2011. 10:27 AM
not a friction mech like that, but a very very VERY high speed version of the "mag single shot" idea that the ZKAR used.

Does this work the same way my S10 does? http://www.instructables.com/id/S10-Knex-Shotgun/
KnexFreak360 (author) says: Aug 15, 2011. 9:31 AM
Aww man, i think its the same concept yes.
Oblivitus says: Aug 15, 2011. 12:06 PM
That's okay. Great minds think alike. This one has a better trigger than mine. Try making the mags removable. I came up with an internally fed mag that could be used with this. Here's a couple pictures;

Cool.

cool
apples!!!!! says: Aug 12, 2011. 6:05 PM
6 rounds for a full auto weapon is not a good thing :P However, it's an intriguing start nonetheless! Does this operate in a similar fashion to the pressure system used in some of the semi-autos floating around?
KnexFreak360 (author) says: Aug 13, 2011. 12:46 PM
I have updated it now its 15 rounds.
apples!!!!! says: Aug 13, 2011. 4:04 PM
Well there you go. Any pics?
KnexFreak360 (author) says: Aug 14, 2011. 8:51 AM
Forget 15 i may have gone to far but 33 rounds.
apples!!!!! says: Aug 14, 2011. 9:06 AM
Lol, well that's much more accurate to the clip size of most real automatic weapons.
KnexFreak360 (author) says: Aug 14, 2011. 11:43 AM
lol but the auctal size of the clip isnt.
apples!!!!! says: Aug 14, 2011. 12:18 PM
Lol, I'm assuming its rather...large?
KnexFreak360 (author) says: Aug 13, 2011. 5:25 PM
Soon.
KnexFreak360 (author) says: Aug 13, 2011. 9:33 AM
Yep.
geodez says: Aug 11, 2011. 6:14 PM
Seems an interesting prototype, It could use a standard-loading magazine instead of an in-line magazine though.
KnexFreak360 (author) says: Aug 13, 2011. 12:46 PM
I changed that.
geodez says: Aug 14, 2011. 11:40 AM
I see.
DJ Radio says: Aug 12, 2011. 11:39 PM
The main thing I see that needs improving is comfort. You need a better handle and a smoother trigger.
KnexFreak360 (author) says: Aug 13, 2011. 9:33 AM
Ok thanks.
Raz1r Knex Bull3t says: Aug 12, 2011. 2:00 PM
Hm, I like the idea! Keep it up!
BlackShadow12 says: Aug 12, 2011. 10:43 AM
you could try increasing the force on the mag ram and see if that increases the range. 4.5*
Football viking boy says: Aug 11, 2011. 5:05 PM
plz post vedio and also what is the range
KnexFreak360 (author) says: Aug 11, 2011. 5:23 PM
Cant get a vid and the range is not good it is a prototype as mentioned.
Football viking boy says: Aug 11, 2011. 6:23 PM
