It looks really cool, but I don't have that many pieces:(

eric1234 (author)2010-09-03

now i get it...its bolt actiton...i typed "knex semi auto gun"

silentassasin21 (author)eric12342010-09-14

No it is not bolt action bolt actions have two chambers one for the mag and one for the actual shot when the bolt is pulled back a bullet is loaded into chamber 1 then pushed into the actual barrel at which its shot.

In knex terms this is bolt action...

eric1234 (author)2010-09-03

i mean i typed "knex semi auto m4" and found this: (

eric1234 (author)2010-09-03

rated it 3.............

eric1234 (author)2010-09-03

im going to rate this a 1...lack of it wont work. when u add more pics ima rate this higher depending on the results after testing

combatknex (author)2009-02-13

and the stock isnt an m4 stock its a m16 stock yes theres a difference. the mag looks funnyand curves to much and its straight

quit complaining you stupid wimp

DJ Radio (author)silentassasin212009-03-02

ck got told!

combatknex (author)DJ Radio2009-03-03

all he said was quit complaining have u seen my figgen mr its 4 times better than this gun:the mag works barrel more realistic by far stock is not an m4 stock at all its an m16 modern stock then the body is wayy to fat and also the "mag has rounded corners i would rate the gun a 2 but i rated it a 5 for ur effort

combatknex (author)combatknex2009-03-03

nvm the pillows were i n the way of the corners of the mag but i dooo reallly like the mag ps im not trying to be harsh i rated ur gun 5

how is it too fat i compared it to my dads m4 carbine and there was not even a close difference

show me a picture of the two guns put together and then another one with the m4carbine on top and knex gun on bottom so i can see a siz difference and if ur dad even has one

um how about NO that is the stupidest idea ever and yes my dad had seen one he fricken holds one ever day in the us marines

What defines an M4 from an M16 is barrel length. Not stock. Just because in Call of Duty 4 the M4 has a collapsable stock doesn't mean a real one has to.

actually what defines them is the m4 has a retractable stock and a shorter barrle for a higher rate of fire the m16 does not have a retractable stock and a proplnged barrel for accuracy and those game have a diffrent portrale than real life wepons

zapple (author)Louis XIV2009-08-07

the m4 has a shorter barrel than the m16 but the real difrence is that the m4 is the tactical verson of the m16. so it has a shorter barrel and a extendable stock. it also has a rail system on some m4's. so the m4 has a shorter barrel AND a extendable stock.

ILIKEPIE333 (author)Louis XIV2009-06-29

The M4 is a carbine (shorter) version of the M16, so that it can be used in CQB/ CQC (close quarters battle/ combat) situations, although the stocks can vary, both models can have the adjustable stock, but it is usually seen on the M4 (sometimes thought to be a defining feature, as in combatknex's case) I hope this helps

combatknex (author)Louis XIV2009-06-20

yes but he called the gun a m4 CARBINE the CARBINE has a collapsable stock

Louis XIV (author)combatknex2009-06-21

Yes, and Carbine refers to the shortened barrel.

combatknex (author)Louis XIV2009-06-21

yeah but it also refers to the collapsable stock the m4a1 is not a shortend barrel and a collapable stock the carbine is the shotend barrel and collapsable stock

Louis XIV (author)combatknex2009-06-22

The M4A1 and the M4 Carbine are the same gun, but the M4A1 is specifically semi or full auto rather than semi or three shot burst. Sure the military use a collapsable stock, but that isn't what makes an M4.
