Many of these modifications are NOT REVERSIBLE , and, if done wrong, will result in irreparable damage to the gun.
Also, i know it's kind of obvious, but performing ANY of these modifications will immediately void the warranty, so don't complain that the store refused to take beck your broken gun! - Note, Some people have commented that Wallmart took back their broken guns after failed mods. THIS IS NOT NORMAL! Toy companies do not follow the maker's creed of "If you can't open it, you don't own it!"
I will also point out key parts that I think should be made of metal, along with CAD drawings of said parts.
All the images in this instructable are available in high quality (so you can actually see what I'm talking about). Just click the boxed "i" in the top left of the image, and click "Original File"!
And, as always, wear safety glasses when playing with modified NERF guns, the darts won't have much of a problem giving you a black eye!
DO NOT MOD A NERF GUN WITH BATTERIES IN IT! 9 volts isn't a lot, until you add current!
The steps are numbered in the following manner:
M # P #, Name
meaning: Mod # Part #, Name (if first part)

Step 1: Pre Mod Stats
Looking at these numbers, the gun did really well pre-mod, better than any other Nerf gun I've used.
Step 2: M1 P1, Belt Air Restrictor Removal
This mod doesn't do much on it's own, but combined with the removal of other air restrictors, it's incredible.
