Introduction: My Pump Action Shotgun V2.5

Picture of My Pump Action Shotgun V2.5

It is a fairly powerful gun with a true trigger and working pump with a 15 shot mag.
I built this in layers so it should be easy to follow the instructions
if you have some knowledge of knex.
1. This gun.
2. Original gun
3. New pump
I recommend that you keep a Grey with you when you are using this gun. To clear Jams just pul back the firing pin and push the Grey down the barrel to push the red back in place, then pull the Grey out.

You can make the mag a large as you want just extend the top.
You might want to make the next version depending on what you use it for.

Step 1: Making the Handle

Picture of Making  the Handle

Same handle i use all the time. fairly simple

Step 2: Making the Body

Picture of Making the Body

1. Build all these.
2-3. Build this also.I just couldn't be bothered to take it apart.
Nothing much else to say. just look at the pictures.
The last pic is of the pump mech.

Step 3: Making the Trigger

I think that you can just use a green instead of the yellow but im not sure.

Step 4: Puting It All Together

Just follow the pictures and ask if you have a problem.

success! a pump action that shoots rods and not orange connectors!

rated 5*   made a way better pump annnnd extensively modded mine to look like a SPAS12

182515 (author)slipknot 6662010-01-23

LOL doesn't even look like my gun. :-)

slipknot 666 (author)1825152010-01-23

haha i know but thats mainly because i didnt have enough pieces ahahaha

182515 (author)slipknot 6662010-01-24

I have been thinking about remaking this gun. if you poet closer pics of the pump i will add it to the gun and give you credit.

slipknot 666 (author)1825152010-01-24

here it is, i basically just added the brown/orange conectors and the two green connectors underneath to keep the pump pull back smoothly. i also made a new trigger because the old one would interfer with internals if it wasn't modded

182515 (author)slipknot 6662010-01-25

Thanks when i get around to remaking this gun i will add this to it. :-)

slipknot 666 (author)1825152010-01-25

sweet, cheers man

182515 (author)slipknot 6662010-01-28

I remade the gun with the new pump and it fires shotgun style now. i will post within a few days hopefully.

Very nice!

i will build.

knexfreak95 (author)slipknot 6662010-01-29

 it doewn't look like a spas12

slipknot 666 (author)knexfreak952010-01-29

meh its close enough considering i only have limited knex to use

An Villain (author)2011-05-02

Technically if it has a cup instead of a ball it is called a ball socket not a ball joint.

TigerNod (author)2010-01-23

Nice gun, innovative design, true trigger, clear instructions; all of the signs of a great knex instructable. I wonder though: does this gun fire individual bullets, or does it fire multiple at a time (shotgun style)?

182515 (author)TigerNod2010-01-23

It only fires individual rods. Though you could make a multi hopper gun that fires 3 white rods.

TigerNod (author)1825152010-01-26

Too bad. It is still worth 3.0 stars, and a half star more for the clear instructions.

182515 (author)TigerNod2010-01-26

I am working on the next version of this that will fire 3 white rods. (Hopefully)

TigerNod (author)1825152010-01-26

Good luck!

182515 (author)TigerNod2010-01-28

I couldn't get it to fire white rods so instead it fires 2 blues. i will post it soon

im building it! 5*

Mr. Muggle (author)~KGB~2009-11-09

wow you rate 5* alot, I like that, the knex community deserves better rates.

~KGB~ (author)Mr. Muggle2009-11-09

ye, i dont really like giving negative comments.... i like to keep people happy. : )

TigerNod (author)~KGB~2010-01-23

But you don't have to rate every instructable best ever! If you don't like a knex gun, you can admit it without making people angry. If you just say it the proper way, you will still keep people happy.  And if you do like a knex gun, try to give more 3, 4 and 4.5 ratings, and only give the best of the best 5 stars.

This comment was only here to help you, and to prevent our ratings system from getting messed up.

~KGB~ (author)TigerNod2010-01-24

ok, i will never rate again....

TigerNod (author)~KGB~2010-01-24

No, that was not what I meant to say at all. Please rate, but don't rate everything fivestars. Otherwise our rating system gets messed up. (Actually our rating system is already messed up, but we can try to make things better...)

I was not trying to discourage you, I was only trying to help the community.
