Introduction: The Goliath ( Final Version) Knex Railgun

Picture of The Goliath ( Final Version) Knex Railgun

Using thousands of pieces and being over 2 1/2 ft and 3-4 lbs this thing is truly a Goliath.
After knex finally shipped me the order I furiously worked on this gun (and promptly used all 100 yellow connectors) until t was finished. This is the most versatile gun ever able to fire anything that fits down the barrel.
This gun has three modes
1. Single shot
2. Mag fed
3. Turret fed

This gun is able to mount any kind of attachments ie..
Extra grips

Step 1: Some Stats

Picture of Some Stats

Range (turret) 120 ft
Range (single shot) 160 ft
Range (mag fed yellow rods) 75 ft

Power (9 bands)

Step 2: Special Features

Picture of Special Features

You may notice the wheels on the stock or maybe you saw the funny looking mount in the front.

The wheels give it a wide base on the bipod and allow it to be moved around

The mount on the front allows for a tr-8 turret

Step 3: Instructions

Heck no I am not wasting a year of my life lol

It uses more pieces than most people have so it would be pointless

Super cool! Your getting a lot better! Do you think you could make a video?

Thanks any ideas for a new project

the CMMG MK47 Mutant

Well I am working on a removable horizontal mag gun currently so maybe later

I don't do replicas. I can use other guns as inspiration but can't replicate them like you or blue mullet

I spend most of my time making guns from my imagination too, I mostly combine aspects of several guns and combine them into one, but yeh from time to time I make a replica :^)
but you should atleast try it man, It's not that hard of a gun and no one has done it before :^)

just btw this gun is nothing compared to a lot of guns like seleziona's f2000 which uses like twice the pieces. you may barely have had enough pieces but most people do. and it would only take a max of 2 hours for instructions if not less

I don't think instructions would be that hard to make, also a lot of people have more than enough pieces for this

Knextremely stupid (author)2015-08-05

It's big to me and used all of my knex (even the brand new ones)

Knextremely stupid (author)2015-08-05

Thanks not sure why they are better though

You should reply to people, it's confusing when you just put another comment up. If your stuck with the half way app then use this -
The desktop version works on the phone as well.
