Knex Compact AST Pistol

Introduction: Knex Compact AST Pistol

About: K'nex is my thing!
Here is my AST pistol. AST standing for Assault, this is a small Magazine-fed pistol, that is easy to use and has good power.

The main reason I am posting this is because of the trigger. It is a neat trigger I came up with a while ago, and I wanted to put it on a gun; thusly this pistol. The video shows how it works best. Range is
45 - 65 feet.

Hope you like it!

Step 1: Parts List

This is the parts list. It is where I list the parts. The parts you need are listed below.

Green ----- 97
White ------63
Blue ------- 3
Grey ------ 1 (this should really be black)

Dark Grey -- 8
Light Grey -- 5
Red ---------- 4
Green ------- 17
Yellow------ 46
White -------- 9
Orange ------7
Blue --------- 4

Blue Spacer ----- 16
Y Connector ----- 10
Ball Socket ------- 1
Elastics. You will need two small elastics, and however many you want for the ram.

Got those? Lets get started!

Step 2: Handle and Such

This is the step for the handle, and the part in front of the handle. Simple.

1: Start with these four pieces
2: Make these four panels. Be sure that one is one yellow shorter than the rest
3: Put them all together with one cross-snapped white rod
4: The shorter one goes in the middle like so
5: Put the four pieces you made first in the spaces so its like this
6: Make these two panels
7: And these two pieces
8: Take one panel and cross snap white rods on it like so
9: Put those bits you made just a moment ago on as shown
10: Put the other panel over like so
11: Put the two parts together
12: Make this little piece
13: From another angle
14: Put it on the piece you already have with a white rod

Step 3: Trigger and Rear Barrel

This is a small step, which contains the trigger mechanism that I made. Get to it!

1: Start with these two panels
2: Make these two bits
3: Put them on like so
4: Put those white rods on
5: Get these parts
6: Snap the parts over the white rods like so
7: Put that last piece you have left onto the top like so. This stop the trigger from popping out of the barrel.

Step 4: Top Barrel

This is the bar thingy that extends over the top of the gun. Its really simple.

1: Make these two panels
2: Make these rails
3: Put those white rods on one of the panels
4: Put the bits on like so, and put the other panel on top. Sorry, the picture of that got deleted or something. Sorry.

Step 5: Top Barrel

This is the part that drops down from the front to make the other end of the slide for the mag. Not too hard.

1: Make these two panels (sorry about the blur)
2: Make these parts
3: Put them on one panel like so
4: Put the other panel on top. That was easy!

Step 6: Odd Bits

Here are just a few little parts you will need to make.

1: Ram
2: Close up
3: Take it up really good
4: Make this
5: Make this

You will put these on in the assembley step.

Step 7: Assembley

This is the fun bit. Here we are going to put it all together and make it ready to fire.

1: Exploded view
2: Put the back barrel and top barrel together like so
3: Put the handle on. Pretty straight forward
4: Connect the two trigger pieces so its like this
5: From a angle
6: What it should look like at the handle
7: Put the front on
8: Just in case you have poor eyesight...
9: Put that piece you made before in like so. Put the small elastic on as shown
10: Place a elastic on the trigger like so
11: Put your elastics on the ram as you want


Step 8: Firing

Here you will learn to fire your gun. If you have any experience you should be able to figure it out, but just in case...

1: Your gun and your ammo (Yellow rods)
2: Take the pusher-inner thingy and hook it onto the bottom of the gun like so
3: Put in your ammo
4: Put as many yellow rods in as you wish, and then place the pusher-inner back on top of all the rods
5: Pull the ram back until it passes the block, and then let it go
6: Take aim....
7: FIRE!

Repeat pulling back and shooting until the magazine is empty.

Step 9: Finished!

You're done! Yay! I hope you like this gun. Have fun!

    no it is a thing whith a ball type thing on the end


    Reply 1 year ago

    This needs the other half of the ball and socket, not the ball part. I don't have it so I used an orange 2 way straight connector cut in half with a tin snips.

    It happens. If you write me up a correct one I'll put it in.

    I think I filled in something I wasn't meant to with green rods, so I almost ran out and had to take some from another build.


    It can often help to take out all the green rods on one of the panels, and then snap in the disconnected panel piece-by-piece. Hope that helps!
