Introduction: Knex CX4 Storm

Picture of Knex CX4 Storm

Hello Instructables, Today I have you my Berretta CX4 Strom. Sorry I haven't been very active lately, I've been busy helping blue mullet build the Weapon of war, also I was on vacation for 2 weeks and I started a HUGE Project. Any ways lets talk about the real Gun. The Berretta CX4 Storm is a Semi Automatic 9mm Pistol Carbine. It is a futuristic design and is used in many ways. Its great accuracy and low recoil makes it a favorite for target shooters, its reliability makes it great for the military.

Now about my CX4 Storm.


Looks Good

Good Weight

8 round mag

Shoots about 30-35 feet

Long pin pull

Jams Often


Trigger mech off Blue Mullets Mp7a1

So thank you guys for viewing my gun and don't be Afraid to drop a comment.

psssst geef mij ns de internals als je klaar bent

dr. richtofen (author)Kona-chan2015-07-24

Dat kan lang duren, want ik bouw hem nog niet.

Kona-chan (author)dr. richtofen2015-07-26

okay :c

dr. richtofen (author)Kona-chan2015-07-27


Wait your building it? But yes that is how the barrel attaches.

Not building it yet, that was just to show how it attaches.
Maybe I'll build it soon-ish, I'll have to see, but it does look pretty cool.

dont have the pieces to build right now, just build an aug today

So many cut pieces where is the challenge in that? Beautiful looking gun but I would highly encourage you to try building without modified pieces to up the build challenge.

do you have internals or are you gonna post a full set?

Lucas The Boss (author)Kona-chan2015-07-17

The only internal I have is of the trigger mech and the handle. Will that work?

Kona-chan (author)Lucas The Boss2015-07-18

not sure

What are you building on the background on picture 9?

That is top secret my good sir, lol I probably won't be able to finish it but it's my Huge Project.

I'm so glad that you were able build this! I absolutely love this gun. The handle looks just a little bit off, but I can ignore that, since the rest looks so epic! The sights, stock, front grip area, it looks great.

Awesome work! You get a patch!

Thank you so much! Glad you like it. Thank you for the patch as well! Yea the handle is a bit off, I hate the white connector handles though so I went with that.

I of course I love it. It's a Cx4 storm. I hate white connector handles too. Too rough.

So anything your working on?

Nah, bro. Started working on a couple of guns, and they didn't work. Might put the K'nex away for a few days, since I'm somewhat frustrated right now. The guns that make it to ibles from me are a very small percentage of what I build.

Awesome weapon dude it looks almost exactly like the storm

Thanks! Glad to know you guys like it.

Thanks man! I worked hard on this one.
