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

video
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

Once again follow the notes on the photos.

Step 9: Put the Gun Together

Notes once again

Step 10: Build the Magazine and Pusher

Notes

Step 11: Adding Rubberbands and Loading

author
bigdylan91 made it!(author)2009-10-06

author
Soopah+Steve made it!(author)2009-10-07

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

author
An+Villain made it!(author)2009-07-05

blue rods.

author
knex_mepalm made it!(author)2009-09-14

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

author
An+Villain made it!(author)2009-09-14

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

author
knex_mepalm made it!(author)2009-09-15

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 made it!(author)2009-09-15

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

author
J4mm3r5 made it!(author)2009-07-07

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

author
An+Villain made it!(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 made it!(author)2009-09-14

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

author
knexjay made it!(author)2009-08-22
