bfhben (author)bighead54542011-08-22

bighead5454 (author)bfhben2011-09-23

I_Am_Canadian is what i think i meant, i dont remember posting that, so im not sure what i meant

bfhben (author)2011-08-22

u could mod it in 2 a m32 grenade launcher it is like a revolver but much bigger and fires grenades lol its a lot of fun watching stuff blow up

Ben_the_Builder (author)2010-11-25

hey jollex, would you be able to tell me which steps are the trigger, firing mech, and barrel please? i cant see the steps properly : / sorry, im colourblind : /

poolio (author)2009-11-03

Are the small wheels nedded?  I dont have any or have never seen them before.

mpk4 (author)poolio2010-09-16

its for the grip

danbaha (author)2010-08-09

This is awesome!

danbaha (author)2010-07-15

Do you need all of the spacers and will it effect it's performance?

dansdoc (author)2010-07-11

do you have to use the orange ones with things on top?

bighead5454 (author)2009-07-10

i have one tini tiny question WHAT IS THE TGKT

TigerNod (author)bighead54542009-07-11

The Grand Knexpert Tournament. The biggest compitition in the knex world. Only Knexperts can join. I belive that Jollex won the first TGKT round with the Railbow rifle.

bighead5454 (author)TigerNod2010-05-13

my reply is late but thanx for tellin me

too bad i have no hope for entering it... un less melee weapons can be entered

TigerNod (author)bighead54542010-05-14

Well, only knexperts can join anyways. I'm not even sure if TGKT exists anymore!

bighead5454 (author)TigerNod2010-05-15

oh *sniff**sniff* now you made me sad!!!

TigerNod (author)bighead54542010-05-16

:-) I didn't make the rules :-P

bighead5454 (author)TigerNod2010-05-16

i no but i wonder who did hmmm *grabs MSR*

TigerNod (author)bighead54542010-05-17

I belive that Dunkis made them, but I'm not sure.

An Villain (author)bighead54542009-07-10

The Grand Knexpert Tournament i think.

jackdb1998 (author)2009-12-22

wat r the end caps

Jango2000 (author)2009-12-19

 no, i Couldn't be bothered to post but i can re-make and send clips

Jango2000 (author)2009-09-24

this gun is awesome!! i built mine and modded it out with 30 rubberbands and extra supports and now it works just like the fatman of fallout 3! it will shoot a mini nuke ( a nice little design i made out of knex ) about 100 feet!

asteinhorn (author)Jango20002009-11-20

 is ur nuke posted?

whats the link?

something94 (author)2009-08-08

do u need to have all the blues. i have like 60 something and i think eliminating the stock would give me enough unless i need that part.

Mace! (author)2009-05-30

I built this and I could only get it to fire a few feet. Plus the grenade didn't explode. Can anybody reccoment the best grenade launcher on the site?

TigerNod (author)Mace!2009-07-11

I think you did something wrong. The best grenade launcher on this site is the RSGL-81v1.9

knexguy (author)Mace!2009-06-27

H.S.S.R V2.

Mace! (author)knexguy2009-07-01

Thanks! I was looking at this and was wondering if it was any good.

knexguy (author)Mace!2009-07-02

It is very good.

mattiscool114 (author)2009-03-25

if you dont have small wheels,can you use small gears???

knexguy (author)mattiscool1142009-06-27

Those pieces are only for comfort, gears would only be less comfortable than the rods they cover.

TigerNod (author)2009-04-07

Why is this gun only added to one group? (I just added it to the really big knex guns group)

noklon (author)2009-03-21

how many pieces?

yannyboy (author)2008-10-13

jollex (author)yannyboy2008-10-13
