Introduction: XM8 / FN SCAR Knex Gun

Picture of 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

jeroenboxi11 (author)2011-07-13

do you have a parts list?

COCOKITTY (author)2010-01-03

Can we substitute cut greys?

uberrobodude (author)COCOKITTY2010-04-25

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

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

COCOKITTY (author)2010-01-04

COCOKITTY (author)2010-01-03

Soopah Steve (author)2008-08-08

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

bigdylan91 (author)Soopah Steve2009-10-06

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

Soopah Steve (author)bigdylan912009-10-07

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

bigdylan91 (author)Soopah Steve2009-10-07

well i didnt look at the ible til' the other day

Skreetsha (author)Soopah Steve2008-08-17

bruce911 (author)Soopah Steve2008-08-09

Soopah Steve (author)bruce9112008-08-09

J4mm3r5 (author)2008-11-21

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

An Villain (author)J4mm3r52009-07-05

blue rods.

knex_mepalm (author)An Villain2009-09-14

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

An Villain (author)knex_mepalm2009-09-14

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

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

An Villain (author)knex_mepalm2009-09-15

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

J4mm3r5 (author)An Villain2009-07-07

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

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.)

An Villain (author)2009-09-14

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

knexjay (author)2009-08-22

u can call them whatever u want it doesnt matter

thomaswatton (author)2009-07-12
