Introduction: Knex M4A1 Version 4

Picture of Knex M4A1 Version 4

Here is my last version of my M4A1. My previous versions had a problem of the bullet not making out of the barrel due to parts being in the way. I also tried to incorporate a new kind of magazine into this. Now for the Pros and Cons:

Looks good
Fires 45-50 ft
Easy to use
Flip sight

Uses some broken parts

Thanks. : )

are you going to post the launcher?

Sorry, it's destroyed.


Well, I moved recently and I had to break down all my knex to move.

well shit
can you try to remake the grenade launcher?

I don't think so, because school just started again and I'm busy with lots of homework. Also, please do not use that kind of offensive language on my instructables, forums, orangeboard, etc.

A little bulky for me...........

AGH! You are soooo close, but just not there yet, and I'll explain why. First off, look at the pic below. As you can see, you have the basic M4 shape, with the edited properties of the M4A1. Your barrel does not get wider as it goes back, and does not get smaller. Your gun is great, don't get me wrong, but I'm just sayin'. Your barrel is not thick enough, and your front sight is not entirely correct. Now lets move to the chamber area...Yours is too thick, and your handle is not far enough from the top of the chamber. As to the stock (I do not mean any offense, but I am trying to give some constructive criticism), it needs to be entirely redone. Sorry, but it is too thick, no angled right, and rather "fat" looking. I am just telling you as I see it. Good job overall, but it needs some small amount of work. Again, I don't want to offend you, and if I did, tell me so I can explain myself. :-)
