Step 1: Gather Materials

- 20 White
- 31 Yellow
- 11 Green
- 6 Red
- 20 Orange
- 3 Light Grey
- 13 Grey

End Connectors
- 8 Brown

- 1 Grey
- 23 Red
- 10 Yellow
- 4 Blue
- 48 White
- 65 Green

- 1 rubber band (works best with one from head of broccoli)
- 3 doubled regular rubber bands. (Twist to "8" and down to double)

- Tape (clear)
- Paper

Step 2: Side Layer Template

Picture of Side Layer Template
This shows the side of the gun without the center layer, which is the next step. Do not start building this layer, but use this as a reference to attach pieces to the center layer.

You will need 2 of these for the sides of the rifle.

Step 3: Construct Center Layer

Picture of Construct Center Layer
Begin building this center layer. This is the lower portion of the gun barrel. If you plan on using this gun for a long time, you may want to cover the marked portion with 3 layers of clear tape. Over time, the firing pin will cut into the joints of the pieces. You may start putting down tape from the right side up to the yellow piece.

Step 4: Combined Layers Template

This diagram shows the position of the three layers. Do not start building the layer from Step 2 yet.

Step 5: Combine Layers

So you probably figured out why I suggested not building the side layers. Now you can easily attach the connectors from the side layers to the white rods.

Step 6: Construct Firing Pin and Trigger

Another AC fan :D As I'm sure you've noticed I was pretty obsessed with AC for a while lol
Lol same! I have every single one but not the NEXT ones, or PP or MOA
crestind (author)  CuddlesMcT4 years ago
The only ones I'm missing are the PSX ones and AC Ninebreaker. ACLR was probably the best AC. The older ones are so hard to find now.
I know right? LRs the only one i still play. To me Ninebreaker was like a variety of AC tests.

Sorry for late reply, but that link doesn't work anymore. Where would you buy this?
Who the hell in their right mind would buy this???????? IAC's spiff uses roughly the same parts, and is way powerful
This was up for sale before the Spiff ever appeared.
Whatever, i'm just saying. $30 ius way too high for a... well, let's just say... a gun like this.
Normally, you dont buy a knex set because of what you can make with it. You buy it because of what parts it has.
Agreed, but a 400 piece tub for $20 or £20 has a better overall parts list.
This gun probably uses more than 400 parts, and it also comes with no micro knex and no knex bricks!
Sorry for late reply, but this gun (including rubberbands) uses 267 parts, this would be good for about $20 because of no micro and what not. BUT this is used parts and $30 for 400 NEW parts is better than $30/$20 267 USED parts. I'm just saying, I got 30 pounds of USED knex for $20, and it had well over 3000 parts.
No..... 20 quid for a 400 piece bucket would be a ripoff.
LOL, I am going to count those pieces, and see if the gun is really worth that. I'll post results later on... LOL.
cool thanks
