Super easy way to mod your Firesrike......
--If you don't believe me you can wikipedia "Venturi effect",
Most people are only moding the barrel and spring!!!!!
Step 1: The restrictor
Everyone knows that this is obviously the first part when moding a Nerf gun....
--Start with cutting out the center. Then work you way outwards so that the dart will fit but have slight resistance.
If your going to use a custom barrel the size will vary.
