The Storm 223 V1.3 Knex Gun

Introduction: The Storm 223 V1.3 Knex Gun

About: Figured it was high time to give this a quick edit. I was an active part of the K'Nex community from about '08, I still occasionally lurk. I did a lot of dumb stuff on here but I'm past it now. I'm currently s…
Hi everyone! This is my fourth posted knex gun, the storm 223. This is the penultimate gun in the storm rifle series, but I am releasing a series of other random guns (pistols, shoguns etc.) Anyway, this gun features two never before done trigger mechanisms, and i mean 2, on the same handle, one for the grenade launcher and one for the main gun.
Version history
  • V1.0: This was a gun which looked similar to what it now is, except the sight was longer, it had no mag and it only had one trigger (for the grenade launcher), and the rest of the gun was a block trigger.
  • V1.1: I added a mag and shortened the sight.
  • V1.2 I made a second, external trigger for the main gun.
  • V1.3 I modded the stock's butt to look like the one on the storm 222

  • 2 True triggers
  • Grenade launcher
  • 60 ft range with 3 rubberbands
  • Mag for 20 yellow rods never jams!
  • Mag for grenade launcher
  • Better stock than my previous guns

  • The grenade luncher will make the grenades explode when firing 1/6 times, and the grenade mag jams a bit
  • Not very accurate

This is my best gun yet, so enjoy!

You could leave the gun like this if you want to or don't have many pieces left, but then it's just another gun (that shoots 60 ft). skip to the Rubberband stage if you want to.

Step 8: Magazine

This is the burrito masters mag again, i just like it. anyway, loosen out the parts slightly on the blue rods to make the ammo fall easier.

Step 9: Adding the Rubberbands

Follow the pictures

Step 10: Loading and Firing

Okay, hopefully you have built the gun. now just to fire it!!!!!
Picture 1 is the ammo
Picture 2 is a close up of the main mag

To load, put 20 yellow rods in the mag of the main gun, and 5 of the grenades in the grenade launcher mag. Pull back the pin in the stock to cock the main gun, pull the external trigger to fire it. Pull back the pin in front of the hand grip to cock the grenade launcher, pull on the small sliding trigger (white rod) to fire it.

Well i hope you like my gun, and i will now start building the storm 224, TJ-SR-V1.3, The Morph gun from the Jak series, The N60 storm from ratchet and clank 3 and anything else that i dream up!

    Hi buttons03, thanks for your advice.  Since reading this comment, I decided to give this girlfriend thing a shot. 

    I found out where your girlfriend lives, and I'm secretly dating her behind your back (well, at least until I told you).

    Thanks for the suggestion.

    All you need to do is not build it, then replace some of the connectors for a smooth edge. Hope this helps,

    Space them out slightly. Also don't build this if you get this message, my later ones are so much better.
