how far does it shoots..?

Soopah Steve (author)2008-08-11

I have 3 Q's. Here they are. 1. What is Sears System? 2. How does it work? 3. Are there anymore K'nex trigger systems out there?

Wafflicious (author)Soopah Steve2008-11-27

1)It has a lock for the firing pin behind the gun that holds it in place untill the trigger is pulled. 2) look above 3) There are about a gajillion k'nex trigger systems

DJ Radio (author)Wafflicious2009-03-01

no, there are just 4. The block trigger, the true trigger, the sear system, and the hammer.

The Jamalam (author)DJ Radio2009-03-09

fail. there are millions. rbg guns, and things like both of those in the 223

DJ Radio (author)The Jamalam2009-03-09

i was talking about ram guns.

The Jamalam (author)DJ Radio2009-03-10

even so there are many types of trigger.

mythbusterma (author)The Jamalam2009-10-11

 yes like the block/true trigger

dragonego (author)2007-04-17

Another Way to get better pic quality is to use Macro-mode if your camera supports it

necropolian (author)dragonego2008-08-09

or ASR, Advanced Shake Reduction.

The Jamalam (author)necropolian2009-03-09

sounds like a movie title :P

necropolian (author)The Jamalam2009-03-11

movie spoiler: the ASR team fails in trying to kill the bad guy, who turns out to be an earthquake...the girl loves him anyway and they get a lot of children. look forward to ASR 2!

The Jamalam (author)necropolian2009-03-11

lol children edition to the team! Yay! I might make some vids of that XD

necropolian (author)The Jamalam2009-03-12

don't forget to include a scottish engineer, an advisor with pointy ears and an android in the team!

The Jamalam (author)necropolian2009-03-12


necropolian (author)The Jamalam2009-03-12

you do know which show they're from, right?

The Jamalam (author)necropolian2009-03-13

star trek...

necropolian (author)The Jamalam2009-03-13

yes, star trek... as far as i know, i'm the only 13 year old guy from our school that watches star trek.

Join the club.

there is no club here.

It is an expression

i know.

necropolian (author)The Jamalam2009-03-12

another cool movie name could be; "Extreme Deep Invader" which is a parody on the movie stealth, then.

so mines hd

how far does it go?

Baldwin1993 (author)2008-11-25

knex forger (author)2007-06-08

hey guess what , i just made this gun semi auto ,should i post it can shoot 40 feet is bigger than this cause it has a butt on it mine is much cooler

mine is better

MI6 (author) knex forger 2008-05-31

Sounds exactly what ive done i got 36-8 ft out of it.

cobra (author) knex forger 2008-02-07

you should post it. I'm posting a small sniper rifle that can shoot over 150 feet, but guess's a block trigger, but it's totally awesome!

anshuvio2 (author) knex forger 2007-07-29


smidge147 (author) knex forger 2007-07-26

TJS (author) knex forger 2007-06-11


TJS (author)TJS2007-06-11

knexsuperbuilderfreak (author)2008-07-18

shall i post mods mods are stock bi pod ammo wheel granade lanucher grande ammo holder

yea sure

and it has a full auto rbg

MI6 (author)2008-06-30

I know i keep on saying this but ive modded this so much its barely recognisable .

MI6 (author)2008-05-31

Wow its only when i see it again 1 month after i built it. It looks quite different from mine ! You could probably recognise it but mine looks more like a P-90 , as it has a hopper on the barrel , also the trigger doesntbreak , the grip and butt and firing pin are improved.

MI6 (author)2008-05-10

The front handle is different, it has more power (4 rubbers) , better firing pin, sights are near back , has a better stock, different barrel which can be slotted in the top or muzzle loaded. The trigger system is still the same , and is very good. Shame that i can't show you my new mods.

MI6 (author)MI62008-05-10

Oh and a hopper :)

MI6 (author)2008-05-10

Wow its weird cos ive made so many mods to this gun that this one looks really different.

MI6 (author)2008-05-04

I made it and it's very good ... with some modding , mostly due to my lack of peices , but also that (no offense) crappy butt you've got. I took it off and put on an arrangement with red connectors with blue rods on the 90degree bits , and yellow semi-cirlce connectors which then click on with blue rods. It is similar to the butt of this gun , but more square. I also improved the firing pin , but it is good , and the trigger system is good.

StyleCore (author)2007-12-19

Just a tip on the firing pin if you take off the gray clip in the front and replace it with an orange clip youll have easier reloading

ultimatesx9 (author)2007-11-20

likekd the look of it, unti li didnt have some peices, but i made a new solution to this, cant wait to fire it!!

knex lover (author)2007-09-14

arent there supposed to be 4 blue spacers?

bballkidx (author)2007-08-03

if by a true trigger u mean a lever that you push in with your finger to make the gun shoot, then yes

knex lover (author)2007-08-02

is this a true trigger?
