Introduction: Knex M4 Carbine

Hello, this is my working knex version of the M4 Carbine. I have seen a lot M4's on 'ibles, and I decided to make one by myself.
I think my version looks pretty good, and the range is 35 feet without front barrel and dark grey connectors as bullets and 40 feet with front barrel with red rods as bullets.
The barrel is from the UMP-45, the removable magazine mechanism too, but I made it even better.
I've built iron sights because I think they're btter than scoops.
Maybe I'll post the instructions but I don't think I've plenty of time.
PLEASE NOTE: You can't use small dark grey connectors as bullets while the front barrel is connected to the gun.

Looks awesome
Comfy handle
Good range
Great working magazine system

High piece count
The bendy blue rods (handel) can snap out frequently

    except for mag, it's the best one i've seen... good job

    this is more of a franchi style m4 because of the mag and some minor diffrences other than that i like it

    do you mean spas 15? thats the only franchi gun to look a bit like an m4

    Not bad, but please don't lie about ranges. There's no way a grey connector is going 50 feet from that.

    Oh I didn't mean grey connectors.
    I meant yellow rods. I agree I hate people who create a good gun and say range 60 feet. But 70 feet is the MAX range, not average. When I got 70 feet, I had wind+good angle+ I took the front barrel.

    Ok, but you should say that in the slideshow.

    I'm gonna fix it right now.

    Looks quite nice, tbh.

    I've made instructions!
    Check it out

    nice 4* mag should be a little bigger but overall nice gun

    Not bad, but make the mag a bit thicker, and the space between the handle and the space where the stock begins to come down is too wide.

    Well, neither have you, otherwise I'm sure there would of been a picture of what you compared it too.

    actually i have but i dont think a teenager should be posting pictures of him self with his weapons

    Thats not what i meant, i meant the m4 next to your replica.

    No, I've just seen pictures of the real one.

    What do you mean?

    i mean if dj radio ever owned an m4 h would know that this is the right specifications and measurments for a civilian issue m4
