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.

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