poor man's lightning bolt mod: (tl;dr version)
remove the venturi from your stock spyder bolt. if unscrewing it doesnt work, you can drill it out if you have the equipment. next, you need some sandpaper and aluminum polish. sand/polish the bolt anywhere it comes in contact with the marker body untill mirror smooth (you can see yourself in the reflection)

optional: drill out the hole between the 2 o-rings on a stock bolt so it is bigger than it was before.

congratulations, you just produced a home-made version of a $50 bolt that is no longer manufactured! this will increase your velocity AT LEAST 10 fps, expect more than that, possibly as high as 30 fps. why would you buy an AKA lightning bolt if you can make your own?
