yodoggie (author)2011-10-29

II KRAV MAGA II (author)2011-01-14

Looks flimsy, but filled with raw power.

99igo (author)2011-01-02

Are the little horizontal connectors nessasary

prodo123 (author)2010-05-31

Different materials are used in different rods. Black rods are a bit heavier and stiffer than normal gray rods, same goes for tan rods and red rods.

nala beamer (author)2010-05-07

i like doughnuts and what are those black things u put in the middle of step 1?

Doctor Who (author)nala beamer2010-05-13

those are orange/brown 2 slot horizontal connectors sliced in half

ZeroGravity9 (author)2010-04-15

 I have a Black Long Rod like that :D

KnexFreek (author)2010-03-16

 Hey doctor who!  I like this gun i five stared it and subscribed! Will you check out my stuff? Thankyou!

Doctor Who (author)2010-01-17

they have some carbon fiber in it while the orange ones and gray ones are pure plastic

stimky666 (author)2010-01-17

Are the black rods really made of carbon fiber?
I've always wondered why they were stronger.

What about the orange ones?

Miles Tails Prower (author)2008-12-27

0.5 stars, because you are cheating. You just destroy pieces.

you dont need destroyed parts to make this gun. it deserves a 3.5

Hmmm... It is just a AST Rifle ripoff, really. The only things that are different is: -Worser handle -Worser barrel -Better trigger

"worser" is not really a word 

yeah and 3.5 suggests that it is "good" which this gun clearly is not.


ILIKEPIE333 (author)2009-08-04

grey rods are more like .50 calibre

stopanator (author)2009-07-23

you copied this from bundrak

psharpep (author)2009-07-03

Haha you say "I'm not responsible for anything you do with this" but to be honest, there's not much we can do with this anyway lol

nerfer (author)2009-06-07

i hate this gun!! do not build it!! i am speaking from persinal experience!!

small letters are fun letters

entenie-1995 (author)2009-04-17

I don't like the gun sorry

entenie-1995 (author)2009-04-17

the gun is not stabel

DJ Radio (author)2008-11-09

ok, 2 notes. 1. The handle is from Frozenfire99's spider massacre v2. you should give credit to him 2. Looks a lot like crestind's AST rifle, but it does have a lot of differences. 4*

Wafflicious (author)DJ Radio2009-02-18

*Keyword* LOOKS =) good suggestions!

Miles Tails Prower (author)2008-11-19

Looks like crestinds AST rifle...

bullet-head (author)2008-09-06

nice hopper!

thomaswatton (author)bullet-head2008-11-15

whats a hopper i dont know LOL

That is a magazine that only works on gravity. If there is no gravity in the place where you are using it, you must have a rod pusher, that pushes the rods down to the barrel.

otrop185 (author)2008-08-16

i'm still not gettin you! tell me from left to right what connectors you put on the middle rod.

Master_Zane (author)2008-10-28

Well, I did all of the steps but it's only shooting like 5 feet. Help?

Doctor Who (author)Master_Zane2008-11-08

ok, where did you put the rubber bands and is the magazine built right?

Master_Zane (author)Doctor Who2008-11-09

Sorry too late. Took it apart already.

Doctor Who (author)Master_Zane2008-11-08

can you send me a picture of your gun?

Miles Tails Prower (author)2008-11-02

Looks like a heavily modded AST rifle from crestind...

Skreetsha (author)2008-10-09

why is this so high rated? not that im saying it isnt good its just that it looks a bit flimsy

Doctor Who (author)Skreetsha2008-10-09

its a decent low piece gun, the front is a little flimsy so shorten it by like 2 sections if you don't like flimsiness. Its a strong gun overall.

mythbusterma (author)Doctor Who2008-10-31

well if youre looking for something durable, try my assualt rifle

Skreetsha (author)Doctor Who2008-10-09

ok im not dissing it it just looked flimsy but you had a clear explanation, so ill rate 5 :)

mythbusterma (author)Skreetsha2008-10-18

a bit flimsy? quite a bit flimsy more like it but notheless a good gun

Skreetsha (author)mythbusterma2008-10-18

yeah i built it but i didnt like it because it doesnt look very nice :/ it more looks like an upgraded big pistol

mythbusterma (author)Skreetsha2008-10-18

big pistol you say?

Skreetsha (author)mythbusterma2008-10-18

nah i was just foolin'around :) it is a rifle but i dont get the impression of a rifle :S

Doctor Who (author)Skreetsha2008-10-18


mythbusterma (author)Doctor Who2008-10-19

Doctor Who (author)mythbusterma2008-10-20

knexguy (author)Skreetsha2008-10-14
