This gun is awesome! I tried to build it, saw it was messed up, rebuilt it because one of the red pieces in the front was blocking the ammo, rotated it, and it's done! Gonna need some heavy duty rubber bands. :)

Element Force (author)2012-07-09

thank you very much for this gun,5*

knex1111111111 (author)2011-03-19

WOW my 5* rating made it 5* I've built many knex guns and when i was building this i thought it wouldn't be sturdy but it was and the pump action is great! =D I also modded the gun A LOT and the mag is much more sturdy and it shoots white rods

post some pics if ya want

ok tomarrow ill try to get them up, i also just modded the trigger

and see the new trigger!!

ok here they are, the mag isn't as good as yours and but the trigger is way better, the mag holds a white rod with a grey connecter attached or just two grey connecters attached by a green rod, another mod i just did was to the origional mag(last pic)

Football viking boy (author)2011-06-06

nice gun

grimmjowking (author)2011-02-28

i modded it to be able to shoot blue rods and it can now go 50 ft with two #64 rubberbands

aleceatsfood (author)2010-12-28

if u still have this gun made, a peice count would be nice cuz im not sure if i have enough of somthing but im still going to try! 5* nice gun

kaleb12345 (author)2010-11-15

yes it does!!!!!!

Mace! (author)2010-07-18

It's quick to reload, yet it takes ages to refill the mag.

CRAZYCREATOR187 (author)Mace!2010-07-18

the design is so when it runs out of ammo it doesn't smash the mag pusher. It isn't designed for speed.

Mace! (author)CRAZYCREATOR1872010-07-19

But you said it was quick to reload....

knexjay (author)Mace!2010-08-14

when he says quick to reload he means quick to pump for another bit of ammo for firing. to refill the mag he means putting the ammo insdide of the mag. hope that helps :D :p

CRAZYCREATOR187 (author)knexjay2010-08-14

exactly, thankyou

Mace! (author)CRAZYCREATOR1872010-08-16

I know I was just joking...

micahmojo2 (author)2009-11-08

This gun is so pwn!!!! i made it and its probably one of my best guns. But maybe u should make the barrel a little bigger.

 whats pwn stand for

TigerNod (author)CRAZYCREATOR1872010-01-24

Internet meme for: Awesome, destructive, powerful, bla bla bla... In this case, it means that it is awesome.

knexjay (author)TigerNod2010-08-14

pwned actually means "Personally Owned" and wat u just said :p (idk how i kno i jus heard it at school and on the internet) :D :D :D

Sry for late reply but watch this video to figure out what pwn means

Dandog50 (author)2010-07-01

asmome gun mate. Could u put a item list with it?

CRAZYCREATOR187 (author)Dandog502010-07-02

I probably could but it would mean getting my knex out again.

lalaland7894 (author)2010-05-15

 Hello, Crazycreator187
this is a great gun i have built it and am really satisfied with the design, but no matter how many or any different types of rubberbands i put on, the gun only shoots about fifteen feet, and the bullet does not even stay straight. Was this the way the gun was intended to be or am i doing something wrong. Thx

Hi, I do not know why this happens, a lot of people seem to have the same problem as you but I never had any problems with mine.

knex obsessed (author)2010-05-21

hey this gun is AWSOME but i have made 2 mods to it
1. Ideal pump for people who don't have many 'y' connectors
2. Iron sights, still need improving but still
but in all this gun beats alot on this site 5 stars

KnexFreek (author)2010-01-24

 awesome gun!!! 5 stars and i subscribed!!!
