Introduction: Knex M4/AR15 Version 2

Picture of Knex M4/AR15 Version 2

Okay first I would like to give credit to Oblivitous for the barrel design. But I was tired of looking at awful replicas of the famous M4. So i decided I was going to totally reconstruct my previous design and actually make it look like an M4. AS FOR BLUE MULLET use this as an good example of an M4. BTW yes this does fire. It fires blue rods and gets up to about 35-45ft. I just took the ram and rubber bands off so you can get a clear view of the gun. For real though, compare it to the picture in this ible that I built it from, and you'll see that it looks a lot like it. Although that grip was added by me. Enjoy.


ALSO PLEASE VOTE FOR ME IN THE LAUNCH IT CONTEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yep, I know. Lol, I eventually ended up making a much better one later though.

The handle should be more slanted. Otherwise it looks good!

this is better than your new one

Lol. My newest one is waaaayyyyy better. Plus, I'm coming out with a version 4 that nails the design in the picture.

I saw v1

Thank you!

No problem man =D Wanna see the secret shottie?

I can tell you one thing though its 9 layers thick lol. And the mag is 5 layers lol. Ill post when I find my camera =D

Now that's a thick gun. *__*

I know right? Just out of curiosity, do Oblivitus's or KnexFreek's mag fed shotguns have removable mags?

Not that I know of.

I just checked and the mags are not removable lol. But they are great guns though =D You build great stuff =D

Thanks! I was just tired of looking at awful replicas of the M4 like Blue Mullet's. So I decided to build it almost exactley like the real thing

Ehhhhh looks ok..

What do you mean by it looks 'ok' . Have you compared it to the picture. Have you seen the other awful designs of the M4 on instructables? If mine is just ok why don't you build one better than mine.

I mean its not bad but its nothing to special either and yes and the front portion looks pretty good but the rest is a bit iffy. and yes i've seen most of them lol but i have also seen the good ones aswell. but if you wanted to make this really good id say get the mag well up to the edge more like move it over and perhaps change the handle angle? and ive built an m16a4/a2 thats pretty darn good wouldnt take much to make it an m4 lol ill try when after i post my latest gun.

Vote for me in the launch it contest please!

I've fixed the mag problem. The handle angle is actually exact on so I'm not changing that, but I'll see if I can get where the handle meets the stock looking different as well as the top rail. BTW I looked at your M16 and i think it needs some work as well no offense. I think I'm going to change the gun up a bunch so expect new pictures if i get it looking right.

Sounds good it should look pretty darn good after that i'll be sure to check it out when theyre up. and yea it definitely wasn't perfect in some spots may i ask where in specific? cause i made another m4 sort of gun that id use if i tryed for an m4.

Mostly the rail, mag, handle, and barrel. Also a little of the stock.

Looks very promising; it's a bit off, though.

Vote for me in the launch it contest please!

Okay, could you tell me what's off because I'd like to improve it. I appreciate constructive criticism, as it can be helpful to me in the future. =D

Alright, well the receiver looks a bit blocky toward the front of the gun, and the area where the stock meets the body/handle isn't the same. The stock area is also much, much larger than it is on the actual weapon. It's just a few small visual defects that can be easily fixed, no worries :)

Thank you so much for telling me that. I did think myself that where the handle and stock meet didn't look right and I actually have an idea to fix it. I think I have an idea about the mag? BTW I fired the gun last night and I couldn't believe how powerful the shot was. It went straight through cardboard about five feet away with four 64's on the gun. Also thanks for the constructive criticism. =D

No problem haha, thanks for accepting it and making the best of it. It should be pretty easy to fix, because you have a good, solid base to it. I look forward to seeing the final product!

Lol, thanks. I'll see if I can get started on it now. I might have to do housework first. : (

Well, there's no rush. Take care of what you need to do and enjoy the time you have afterwards!

Dang! i tried making the adjustments but it just weakened the gun's design. I needed the gun to be sturdy so I switched it back to it's original form but made the stock a bit longer for comfort. Don't you think it looks like the gun just how it is? : (
