Introduction: The NB-4 Pistol

Picture of The NB-4 Pistol

Check my Sipriani V3.0 too!

Here it is!
It's a powerful 5 shot gun with an average range of 50 to 60 ft.
If you're bored or something try to decode the name.
I especially like this gun because of it's smooth lines and it can pack one heck of a punch for a gun of it's size.
Heres some pro's and no's:

-Great Range
-Great Performance
-Magazine never jams
-Looks "slick"

-Lots of parts for a pistol
-A 5 shot mag which might be short when you're in a knex war (The El Diablo's mag can be used on this gun if you want to go in combat).

Like it?
Building time, then!

Step 1: Strength Sides

Picture of Strength Sides

These parts are for added body strength and might even be required for a gun that must be able to survive itself.

Step 2: Mag Sides

Picture of Mag Sides

These are the mag sides which keep the bullets in place.

Step 3: Mag Pusher

This is the part which pulls up the bullets for a auto-reload

Step 4: Firing Rod

Picture of Firing Rod

This part is the part which actually fires the bullets.
I used a small amount of tape first, and then a rubberband wrapped around it, to make it less of an impact on the gun.

Step 5: Trigger

This is the new trigger.
It's asymetrical, so you might have to put the tans on the other side of the trigger if you're a righty.

Step 6: Mag Front and Rear

These bits are the actual mag tip.

Step 7: Handle

Having trouble?
Ask it in a comment.

Step 8: Barrel

This is the part which holds the loaded bullet until it's fired.

Step 9: Assembly

Having Trouble?
Ask it in a Comment and i'll reply as soon as possible.

Step 10: You're Done!!!

I made this and it is awesome. 5 stars.

~Meme~ (author)2012-01-28

I love it. Best pistol ever!!!!!!!!!!!. (Its better than oblivitus's ultra pistol 2).

Fred the evil puppet (author)2011-03-20

What does NB-4 actually stand for?

I was a GTA IV addict back when i made this, so it's a short for 'N'iko 'B'ellic from GTA '4'

skyfaller (author)Skreetsha2011-03-24

It could also stand for... Not bad ''4'' (a) pistol. :D

Skreetsha (author)skyfaller2011-03-26

Lol, didn't even think of that one. Thanks man

skyfaller (author)Skreetsha2011-03-31

I said it for fun, but i guess your welcome.

DracoUltima (author)2011-02-06

Is this gun's range as he says it is? I'm somewhat skeptical about 60 feet.....I'll start building when I get home.

Skreetsha (author)DracoUltima2011-02-08

60 Might be a bit high, but that's about the highest i ever got. It averages in at around 45 feet.

DracoUltima (author)Skreetsha2011-02-14

I get around 40, not bad but I like your RX9 better.

Skreetsha (author)DracoUltima2011-02-15

The inverted crossbow? Ye, i really liked that 1 too. Thanks

DracoUltima (author)Skreetsha2011-02-15

Be sure to check on my new sub machine gun. It uses a rail system, not very strong but something unique, it will be posted within a day or two.

SomeAsianKid (author)2011-01-27

I added a slide to it, it works great thanks :DDD

Heres the slide :D

knex shooter (author)2010-05-12

CODKING (author)2010-05-07

JaymzFlipper (author)2010-03-14

 Im half a second old and made this in one hundredth of a second!!!


mister97 (author)2009-07-21

ok this made me stop making the gun its confusing, frustrating, and i thought i needed 2 more pieces but i needed 4 more

blastboydanny (author)mister972010-02-11

it stoped me u realy need more pictures of differnent angles and step by stap instructions to make the complicated bits it looks like a good gun but bad instructable 1*

Merugop (author)mister972009-12-26

 its kind of easy

linkkiller (author)2009-05-22

is the white rod the same as the gray rod

coreyt (author)linkkiller2009-07-08

no a white rod dosent bend a grey will if you dont have a white or clear as i would think use a black one its not the best but it works

Pizzapie500 (author)coreyt2010-01-19

I know this is a really late reply, but where do you get the clear rods? I looked for it on and I couldn't find it. If you find it can you give me a link?

cool bas3 (author)Pizzapie5002010-02-02

you get them in the knex starbust spinner set
but there are only 2 of them in that set


sanchixx (author)2010-01-31

rrr67 (author)2010-01-24

just pull back the ram really hard until u can see the mag pusher move up but not too hard  or it will break the gun.

rrr67 (author)2010-01-24

are those the blue spacers from step 1 or are they new

rrr67 (author)2010-01-24

are the blue spacers needed now or in a later step? im confused... :-0

Merugop (author)2009-12-27

 I am making a smaller version of the NB-4pistol can i post it as the NB-3 pistol (with of course credits to you)?

Spc force (author)2009-07-29

does it reli matter what is in the inside???

mettaurlover (author)Spc force2009-08-10

yes, actually, it does. just try building my gun without caring about the innards. it's MUCH simpler than this. you'll end up with a piece of crap that doesn't work. built correctly, it's actually very easy to us, and gets great force and range.

Merugop (author)mettaurlover2009-12-26

 no it odesn't only between the green connectors is important.

knex_mepalm (author)mettaurlover2009-08-19

im working on a bigger barrel designed for biggger rounds but with a twist, the ram has 0 friction (from the barrel anyways)

mettaurlover (author)knex_mepalm2009-08-19

nice. mine doesn't even have a ram; no wasted energy.

knex_mepalm (author)mettaurlover2009-08-19

there would be wasrted energy from the notion of it snapping back into the position and it rubbing the sides

mettaurlover (author)knex_mepalm2009-08-20

not so much; it's as low friction as a barrel can be. also, the ammo isn't attached to the RB, therefore eliminating the problem. no unnecessary wasted energy.

Merugop (author)2009-12-26

 lol i can make this gun without instuctions i made it like 10 times

Killbunny (author)2009-12-14

It's exactly the El Diablo's handle.
I mean EXACTLY. Except for ONE PIECE.

Merugop (author)Killbunny2009-12-26

the first gun i made on Ible and its still my favo

Merugop (author)Killbunny2009-12-26

 Is it forbidden to copy one of your own guns?

Killer~SafeCracker (author)2009-08-23

My friend shot me in the neck with this. It hurts.
