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.
Step 3: M1 P2
This is a long and tedious mod, since it has to be repeated many times.
However, it's probably the easiest mod to do, since you don't have to disassemble the gun.
Step 4: GUN DISASEMBLY Part One
Step 5: Feed Cover Removal
Step 6: GUN DISASEMBLY Part Two
Luckily, not all of them need to be removed!
Step 7: M2 P1, Master Air Restrictor Removal
Use extreme caution when lifting the piston out of the action, there are many thin plastic parts that could snap of bent wrong.
When I first performed this mod, the firing distance actually dropped, but i quickly figured out why: The master air restrictor acted as a chamber seal during the firing sequence. Without it, it is necessary (on some guns) to spread a bit of Vaseline or other gel on the tip of the plunger chamber (marked in picture). This will greatly improve the function of the gun by keeping the seal moist, and airtight.
Step 8: That's It, for Now.
I will update this Instructable with future mods that I do!
Future mod list:
- Round Counter
- Extended belt -- maybe not, this would put too much stress on the belt feeder (if the belt was hanging)
- Rechargeable battery - possibly an old laptop batt?
- Better ammo box
- Better belt feed - see next item
- Metal components (and CAD Drawings)
- Stefans (requires belt post removal...)
