Introduction: Knex Gun: Savage

About: U.B. Electrical Engineering. I enjoy building with Knex and I have been using this site for a few years now. So, subscribe if you like what I do.
Hi guys, I'm back after quite a long break! This is my newest Knex gun and one which I built back last summer and also one which I enjoy quite a lot. Only now have I even bothered uploading the photos to my mac.

So what's cool/ good/ NEW about this gun?
  • great range- with three bands, I got around 70ish feet
  • amazing power- with three bands, I shot through a pop can
  • extremely comfy handle
  • bullpup
  • nice looking
  • sights
  • Quick reload makes it good for battle
  • NEW slingshot mech- more on this later
I'd like to thank The Red Book of Westmarch for creating his bullpup rifle which the body and handle of this gun are based off of. (I'm not the best at making guns which look nice, I'm more of a mechanism kind of guy.)

I think it is important to note that this gun is one of the most comfortable which I have handled and I am rather impressed with how it turned out. Also the new slingshot mech, which is rather cool and very effective, has worked without fail in providing a snug hold for the bullet without inhibiting the speed of the ammo as it fires.

This is a fun, powerful, and comfortable gun which is both easy to build and easy to modify. Let me know what you think!

*You will need either 2 orthodontic rubber bands (for braces) or, if you were lucky and able to avoid bands and/ or braces all together, 1 or 2 small rubber bands which you may need to fold in half, perhaps multiple times, in order to build the small front portion which, keeps the rubber bands for firing, on the gun. Make sense? (pic 4)

*You will need a hybrid standard to mini Knex piece to make this trigger. Or you could try and modify it to use a different piece which shouldn't be too hard. (pic 5)

So, without further ado, I present my newest Knex gun: Savage, enjoy!

By the way, image notes are your friend.

Step 1: Left Panel

For the first step, we shall tackle the first outer panel. So, basically these instructions show an aerial view of the gun as it is build essentially from the ground up. Follow image notes.

1. The panel
2. Close up
3. Close up
4. Close up
5. Add blue rods
6. Close up
7. Close up
8. Close up

Easy enough. Move along.

Step 2: Inside the Barrel 1

The first parts of the inner barrel, mainly filler, are added here. Look at image notes.

1. Build
2. Connect
3. Connect
4. Add
5. Another view
6. Build
7. Layer them
8. Another view

I decided to break up the barrel steps so as there was not one step with like one hundred pictures.

Step 3: Inside the Barrel 2

This is a large chunk which includes the actual track for the bullet, the holder for the firing bands, and some more filler. I have the small rubber bands pictured in this step, but they are not added to the gun until step 11 so set them aside. Image notes.

24. Another view/ add the other clip on the other side
25. Gather your chunk and left over pieces
26. Add the large section you just made to the first outer panel
27. View from the backside, note how it is attached

29. Close up
30. Add this piece from pic 17, you should now have one piece from that picture left
31. Add the last piece from pic 17 to the backside of the gun
32. Close up

The small rubber bands are not used in this step.
That was probably the longest step but I don't think the hardest. There's more to come.

Step 4: New Slingshot Mechanism

As a part of this step we will make the new slingshot mech, or rather the part that locks the bullet in place. You will need to follow the image notes for this step.

1. Build/ gather
2. Navigate to this location on your outer panel
3. Put the end of the white rod in the hole between the rod and connector
4. Close up from backside
5. Grab this green piece
6. Attach it like so
7. Close up
8. Follow image notes
9. Fold the yellow connector back down
10. Add the last sub-assembly from pic 1
11. Push the green rods down into the slots on the yellow connectors
12. Close up of the assembly

A bit confusing, but it works very well.

Step 5: Handle

This is the step in which you will build a very comfy handle to be fitted to your gun. Image notes.

1. Build/ gather
2. Attach

31. Clip the back of the handle to the blue rod with the spacers
32. Close up
33. Add the two remaining blue spacers from pic 7
34. Slide the front of the handle into place
35. Close up
36. View from the backside
37. What you should now have

Hopefully you made it through that step and now we must move on.

Step 6: Trigger Assembly

This is the bullpup ratchet which you shall add to your gun now. You need a hybrid standard to mini Knex piece for this trigger. Shown in pic 5 of the intro and pic 8 of this step. Image notes will help you on this step, look at them.

1. Build
2. Close up
3. Close up
4. Attach

11. Add two gray spacers here
12. Add the assembly here
13. Close up
14. What you've attached should look like this
15. Begin to slide this piece through the gap in the top of the handle between the two green connectors
16. Here is a cutaway view of how it should fit through the handle
17. Slide it all of the way through
18. And attach
19. Close up

You are almost done! The hardest parts are out of the way.

After this step you will add the final panel and the sights.

Step 8: Right Panel

Just putting on the final outer panel before attaching the sights. Image notes.

1. Build the panel
2. Gather
3. Put all four of them here
4. Attach your outer panel

Next you just have the sights and some finishing touches!

Step 9: Sights

Short step just add the sights. Image notes.

1. Build/ gather
2. Another view
3. Go to this part of the gun
4. Attach
5. Close up
6. Another view

The next step is just little touch up pieces, nothing bad at all.

Step 10: Finishing Touches

Congrats, you're almost done! Image notes.

1. Gather
2. Flip the gun over and start on this end. I shoot lefty so I added them onto the left side of the gun. For any righty gun wielders, feel free to add all of the tan clips to the other side of the gun.
3. Attach
4. Attach
5. Attach
6. Attach

Hopefully you used up all 17 of the clips. If not go back and check to make sure you didn't miss any.

You will learn how to load and fire on the next step.

Step 11: Loading and Firing

This step includes loading and firing as well as showing how to attach the two small rubber bands. Image notes.

1. First grab a band for your trigger
2. Loop it through and attach like so
3. View from backside
4. Grab a band or however many you want for firing
5. Remove the hinges
6. Close up of the small gap in which the rubber band goes
7. Slide it through like so
8. Move it to this location
9. Reattach your hinges
10. Here you see the placement of the first small rubber band
11. It loops to this side
12. Another view
13. Add a second one right over it

*It appears that when I first took the pictures to make this gun back in the summer, I left out how to load and fire, so at this point I switched to a crude rail that I built which helps document how to load and fire. It still works the same and looks the same, it just doesn't include the rest of the gun. It is only the firing mechanism. Good luck. You will need to read the image notes.

14. Here is my replica. You'll notice that the lower part is different because, like I said, I just built the barrel and enough to keep it held together.
15. What your barrel should look like, these rails guide the bullet
16. The bullet (If you sharpen it, I am not responsible for any harm as it can penetrate skin if you sharpen it enough!)
17. Set it between the rails
18. Push it all of the way back to the green rod
19. Read image note
20. Read image note
21. Pull your rubber band back and pull it onto the back of the white connector as you would with any ratchet gun.
22. Your hybrid piece should hold the ratchet from spinning
23. When you pull the trigger, your hybrid piece moves forward allowing the ratchet to spin.
24. There you have it!

You are now trained in using the Savage! If your bullet did not lock/ is loose/ not held in or if your trigger keeps breaking, refer to the next step for troubleshooting.

Step 12: Troubleshooting

Any problems? Check here! Image notes!

1. If your gun has issues it is with either the new mech or the trigger.
2. If the trigger breaks under pressure from too many bands, simply add a dab of hot glue to the connection between the blue rod and orange connector shown in the box. If your trigger is breaking in the spot of the other image note, simply loosen up your trigger band. Nothing too hard to fix.
3. If you have a problem with your bullet not staying in place, this area is causing it.
4. Push your bullet into place and it should look like this with the end of the tab on the red connector touching the end of the tab on the Y-connector with the green rod in the back applying pressure.
5. If it looks like this, with space between the green rod, red connector, and Y-connector, you have a problem and I have the solution.
6. Simply apply pressure to the top of the green connector until you hear a faint click. (It's possible that you won't hear a click, just make sure it is all of the way down.) By pushing down on the green connector, it fixes an issue where the Y-connector attached to the green connector and blue rod (image note) becomes detached slightly from the blue rod. When you push down, it reattaches and moves the assembly up just enough to stay snug with the bullet. Hope you understood that!
7. How it should now look.
8. Close up. If it is snug, you will be able to shake the gun and the bullet will stay in place.

Hope this helped! If you're still having problems, feel free to leave a question in the comments.

Step 13: You're Done

Well done! You made it through Savage! Enjoy your new gun and of course, be careful.

It's good to be back and hopefully I'll have more to come soon!
