Okay so this is my first write up and I'm hoping some of you will cut me some slack. So heres the low down I have been planning this for awhile now and with the last sum of my money in paypal I bough two NB-1's. Knowing they would suck I though to myself about the internals and what would lie ahead and once I made that last cut into the shell I knew exactly what to do! So in this mod I will be telling you how to replace the pump and add an airtank to get singled AT2k ranges.

So heres your typical NB-1.

Posted Image

Ranges are very inconsisteant due to the fact that the faster you pump it the further it will go. With my 13 year old arms I could only squeeze about twenty feet out of it.


To start your going to need to open the gun up by dremel. I would reccomend using the thinnest cutting wheel you can find as it will make for less work later.

Once you get it opened you will find this.

Posted Image

Pretty self explanitory just a pump minus a check valve, the arrow barrel, and some exposed tubing. So after I saw what the inners looked like I went diving into my parts bin and found this.

Posted Image

Yes an airtech 3000 plunger tube. So trying too keep it as clean as possible I intended to make the original pump of the NB-1 fit into the 3k pump. Upon removal of the pump of the NB-1 I met my worst nitemare.

Posted Image

Not only is it terrible it couldnt fit into the pump=( I removed the plunger head and it still wouldnt fit because of a ring of plastic that lies under the original plunger head. Once that is dremeled down test it out and make sure it can move freely in the 3k plunger tube. After all of that I went and found some mysterious o-ring in which I dont know the size and/or gun it came off of and slapped it on and added a nitfinder like o-ring to stabilize the mysterious one. Then your going to want to shave down the 3K plunger tube to make it fit in the shell. Finished plunger head should look like this. (Also please don't lube it because it will only make the seal greater and will make pumping it harder.)

Posted Image

So now the plunger assemply is done now your going to make room for the tubing in the shell. There are screw-port-like structures the restrict tubing room. I got rid of with some snips

Posted Image

Thats better, now we have room for our tubing! So go get some 1/4 inch OD clear vynal tubing and connect the original orange tubing from the 3k pump and the new clear vynal tubing with a connector. This seems really easy, but it's not. Your going to need to minimize the connector dramaticly! I cut off a couple of the barbs off because when I used the stock connector there wouldnt be enough space and it would crimp the tubing a lot making it harder to pump. So I grabbed my trusty dremel and went at it and was left with this

Posted Image

Tiny aint it?(haha) With the mini connector you will have enough room to keep the tubing in the shell and improve its cleanlieness. Also please add some goop over the connector and the two tubes to improve the life of your NB-2000 because when your rerouting the tubing it will have a tendancy to slip out. To rerout the tubing I just ran a loop through the handel and under the 3k pump out of the hole where the end of the original pump was. Please leave enough tubing to connect to the air tank too.

Overall internals should look like this

Posted Image

Almost there!!!

This is where the most frustrating part of the mod is;closing it up. Now the NB-1 is what I call a "glue gun" due to the fact that the two sides of the shells are glued together. To keep the shells together I used some 1 minute epoxy because I'm very impatient. Also i would reccomend using a vise to hold the two halves of the shells together, but I dont own one so I was a man and as angel would say "used my hands". Once that is done your NB-2000 is almost finished except for the following:

An air tank and a paint job.

So the tank part is simple just grab your favorite air tech series tank(I chose the 2k) and connect it to the tubing coming out of the hole in the back where the tubing from the pump should be located. I would reccoment using goop for this one too. Then grab around 8 inches of your favorite barrel material (I used PETG) and slap it onto the mouth of the tank, add some goop, and your ready to go. Then glue the tank on. The final step in making your NB-2000 is giving it a trigger, but I couldn't find anything so I used a PVC ring After that's done, whammm an NB-2000 is born. Now I (as of now) do not have any pictures of the finished product because the glue holding the gun is still curing, but I'll update this write up as soon as everything is 100% done.
One last thing: I wouldn't reccoment going over 6 pumps with this because of the risk of an extreme case of Tankexplodinginyourfaceidous; a very agressive disease effecting most nerfers with external tanks.

PS: Very sorry for the blurry pics because my camera likes to swim in other people's pools.

Edit:Pictures!!!!

I was extremely confused until I realized you were going to be integrating an air tank. Not a bad idea.

Looks sick! Great work, and cool paint job. Very clean! Seems strange to fire though.

Very, very nice. I can't even remember if I sold my NB-1...I hope not. Off to look...beacuse this thing is awesome.

Does look a tad awkward to fire though...how does it work for you? (because that's really all that matters)

Great mod and use of a terrible gun. I love th pj on that thing and I've always loved how the nb-1 looked so I'm glad to see that you kept the look of the original gun.

That is awesome man and mad props for coming up with something way out of the blue. The only complain I could have against this blaster is that I wish you could have rigged up some kind of trigger so you could fire the blaster with out having to move one hand all the way to the back. Then again this is so novel I really shouldn't be asking for anything. So thank you for some thing refreshing.

P.S. Woot 100th post!

Thanks everyone for the positive feedback. Also for all of you that kept asking me if the gun is akward to fire the answer is yes! Well it's fine for me because Ive been using it nonstop, but I guess to the average joe it would be a tad akward to fire. Also FA_24 and cheesypizza please add this to your directories as it is both a mod and has internals.

That is all.
