Tan Clips - 7
Blue Spacers -31

*This list is pieces to build one shell and the stand
**This list may be slightly inaccurate

Step 2: Barrel

Picture of Barrel
Make the barrel.


1. Sides
2. Top
3. Bottom
4. Assembled
5. Connection for pump slide goes on bottom.

Step 3: Pump

Picture of Pump
Build the pump. This is a version of the pump used on the OSNJCKMA2, pretty much the greatest gun ever


1. Pump segment
2. Put 8 segments on, spaced with gray connectors
3. Rear of the pump. Pushes the ram rod back
4. Attach the rear of the pump
5. Front of the pump. The ball joint is where the rubber band attaches
6. Sliders. The pump slide goes thru here

Step 4: Breech

Picture of Breech
The breech of the shotgun (where you load the shells)


1. Top view
2. Bottom
3. Some more of the top
4. Add this thing to the bottom
5. Add orange supporters
6. Finished

Step 5: Body

Picture of Body
The bulk of the gun.


1. One side of the frame (make two of these)
2. Put them together like this (notice the blue connecting rods and the slight changes on the side facing you)
3. This holds the back of the pump slide. Attaches to the underside of the body
4. Spacer. Holds the sides apart at the bottom
5. Put on spacer

Step 6: Stock



1. The attached butt of the stock
2. Skeleton of the butt
3. Top of the butt
4. Bottom of the butt
5. Connect like so (only top is shown connected. Bottom goes on the same way)

This next part is sorta hard to show because this part of the stock is built into the body.

6. Boundary between the body and the stock
7. Middle of the stock
8. End of the stock
9. Whole stock
10. Underside
11. Underside of front
12. Details

Step 7: Connect breech and body

Picture of Connect breech and body

1. Connect the top
2. Connect the bottom. (shown w/o the orange connectors for greater visibility)
3. Finished

Step 8: Attach the barrel

Picture of Attach the barrel
Self explanatory.


1. Side view
2. Bottom view
3. Support. Holds the body and the barrel rigid.
4. Attach to body
5. Attach to barrel

Step 9: Ram Rod

Picture of Ram Rod

Step 10: Add Pump and Ram Rod

Picture of Add Pump and Ram Rod
This step is a little tricky.


1. How the pump connects with the ram rod
2. How they both fit into the gun
3. Back of the ram rod
4. The gray rod is the pump slide. It requires a little pulling to get it to connect between its place on the barrel and the one on the body.

Step 11: Trigger

Picture of Trigger
A string trigger. Yeah... I know.......Not very creative. If anyone has a better idea, I'm open to it.


1. The trigger. It works well if you put the string in between the orange connectors.
2. Trigger attaches to the gun
3. Gray rods run up to a block trigger. String ties on to the back (shown w/o the pump)

Step 12: Handle

Picture of Handle
I don't know if anyone has made this handle before, but if you have, you are hereby acknowledged.


1. Make these
2. Combine
3. Connect to gun. There is a gray connector on the bottom, too.

Step 13: Shell

Picture of Shell
Main ammunition. To load a shell, just push open one end with your thumb and drop the shot in.


1. The shell
2. The shot
3. A finished shell. The rubber band is to hold the ends closed.

Step 14: Adding Rubber Bands and Firing

Picture of Adding Rubber Bands and Firing
Name says it all.


1. Ram Rod bands
2. Trigger bands
3. Bands for the block
4. Bands on the pump
5. How the shell loads into the breech

The ram rod must be pumped before you can push the shell into place. When doing so, swing the shell down into the opening, and the sides should be lifted out of the way by the red connectors on either side, allowing the shot to be lined up in the barrel. To take the shell out, pump the gun and use your thumb to pull up on the black Y clip and swing it up.

If you have two shells, it takes roughly nine seconds to fire two shots.

6. The shell swung into place

Be warned! You will lose green rods when firing this. I suggest you fire into corners in brightly lit rooms to minimize this risk.

Step 15: Stand

Picture of Stand
An optional step. While I was building the gun, I noticed it was none too good at standing up by itself, so I made this little stand to hold it. Useful for display purposes, or for holding the gun steady while modding it.


1. Front
2. Side

Place under the pump.

Step 16: Finished

Picture of Finished
Congrats! You now have a cool shotgun. Please comment and rate. Also, I think it would be awesome if anyone improved on this. It's sort of a new concept, and it would be great if people developed it.

Seriously?what a shame it's an awesome gun

do you need the decapitated grey connector?
MattJoeP sdds3 years ago
Unfortunately yes, I tried to see if a ball joint socket would work and there are key differences between them. The "decapatated" grey connector has no "snap" to hold the ball in and therefore, the shell can move smoothly. The ball hub has little ridges or extra length to the curve which allows the ball to be snapped into the socket. Hope this helps!

Matt247Matt5 years ago
hi DRADIS im new and im building ur gun but i cant see where the block trigger is. I cant see it plzzz culd you help thanks
 you stole my name!
AgentCWG5 years ago
This is a good gun, I removed the stock stregnthened the handle and removed the barrel on my own one. I find mine doesn't shoot great lengths but I believe that is due to the bands I used.
DJ Radio5 years ago
How many bands can the pump handle max?
~Aeronous~5 years ago
how many shots can u fit in the mag?
a nice gun, not flemsy at all and it has pretty good range. i love the pump action.
Lowney5 years ago
It looks a bit flimsy to me. Is it sturdy? Can someone other than DRADIS tell me (I'm not saying that he's a liar, he just might be 'optimistic' about his own gun.)
Raiden97 Lowney5 years ago
im building it right now, ill tell you
Lowney Raiden975 years ago
K thanks!
Raiden97 Lowney5 years ago
Actually this isnt flimsy that much, it wont bend that much for me
Lowney Raiden975 years ago
:D Check out my new sniper instructable!
What is Y clips
you can easily tell, it looks like a Y, it also hooks on to ball joints and the side of a rod
Unseen9975 years ago
can you use something else for the ammo like blue rods?
NYPA5 years ago
Would it be of high recommendation to use a tan and black rod?
NYPA5 years ago
Holy camoli! i can build it!
Also after I put the dental floss behind the vertical white peg what do I do with it?
