Introduction: XM8 / FN SCAR Knex Gun

This is instructions for Alingarhs knex weapon. I did get permission from him to make and may I say this is the most powerful magazine fed gun with only 2 elastics that I ever made. Without further ado here are the instructions.

If you need more instructions on a step or you are having problems with the gun post a comment or message me.

The pics are great by the way.

I am making a video today with my friend showing its aim and power.
If you see any mistakes tell me too and also spelling errors.

Step 1: Front of Barrel

This step is self explanatory

Step 2: Top Rail/support

Follow the notes on the pictures.

Step 3: Build the Firing Pin

Watch the hopefully detailed video to build the firing pin.

Step 4: Build the Butt of the Gun

Follow the notes on the photos.

I think there are enough notes for everyone to understand

Step 5: Bottom Rail/support

Follow the notes on the pictures

Step 6: Build the Barrel

Follow the notes on the pictures.

Step 7: Barrel Connector

Easiest step of the gun

Step 8: Walls,trigger and Handle

Can we substitute cut greys?

author
uberrobodude (author)COCOKITTY2010-04-25

I think those are cut greys. I was wondering if we could substitute ball joints.

author

You can't because they will clip on to the bullets

Hey..... This handle looks VERY familiar... like Banana Inventor's One Shot True Trigger Gun... hmmmm.

author
bigdylan91 (author)Soopah Steve2009-10-06

it actually looks like mepains trigger on his sniper just modded and so does the handle

author
Soopah Steve (author)bigdylan912009-10-07

You are a bit late.... about a year late.... 0.o

author
Skreetsha (author)Soopah Steve2008-08-17

author
bruce911 (author)Soopah Steve2008-08-09

Also what does it fire?? (It may say somewhere I just probably haven't read it 'cos I'm lazy!)

author
An Villain (author)J4mm3r52009-07-05

blue rods.

author
knex_mepalm (author)An Villain2009-09-14

wow, jusst wow, blue rods, hmm maybe i can mod his to fit red rods...

author
An Villain (author)knex_mepalm2009-09-14

yeah, these kinds usually fire blue rods to have the highest caliber ammo but still look realistic.

author
knex_mepalm (author)An Villain2009-09-15

im going to invent a true AR which actually shoots more than once per time you pulll trigger, to do that you connect the trigger to the motor, so it flips it when you pull and release the trigger

author
An Villain (author)knex_mepalm2009-09-15

that will be very difficult unless you modify the actual circuitry.

author
J4mm3r5 (author)An Villain2009-07-07

Um Late reply....but look down. I quote: "IGNORE BOTH OF THOSE COMMENTS!!!!!!!!!!!!!"

author
An Villain (author)2009-09-14

to make it look more finished, replace the last blue connector with a yellow/grey connector and clip 2 more brown connectors on the end of the brown connectors sticking out (in the manner of the okp handle.)

author
An Villain (author)2009-09-14

the more i look at this, the simpler it gets.

author
knexjay (author)2009-08-22

author
thomaswatton (author)2009-07-12
