Beretta CX4 Storm Field Strip

The Beretta CX4 Storm is a blowback pistol caliber carbine that is about as no-frills as they come. That said, they work, they shoot well, and they use Beretta’s pistol magazines. Let’s take it apart.

– [Alex] Hey guys it’s Alex C. with TFP TV, and for today’s field strip we’re going to go ahead and take down a Beretta CX4 Storm carbine.

These are really cool nifty blowback 9 millimeter carbines that that Beretta 92 magazines.

The reason I actually bought this was, the 92 FS was one of the first pistols I ever had, it was in 9 millimeter, so I thought it would be cool to have a long gun that also took those magazines in the same caliber.

So, that’s how I ended up with this guy.

But anyways, let’s go ahead and check the chamber, remove that magazine.

This is a 30-round factory Beretta magazine, by the way.

Not something I’d run in a pistol but it’s cool to run it in a carbine.

So once you’ve done that, go ahead and press out this cross pin.

It’s got a little spring-loaded bit in it that does retain it in there.

Although it is not captive so it will come out.

After this you can separate the upper and lower receivers by just pulling them apart from each other.

And go ahead and pull the charging handle back a little bit.

And pull it out once it gets to that enlarged section.

And go ahead and pull the bolt through the rear as well.

You’ll notice that the bolt is very substantial on this gun.

So remove the recoil spring by rotating it 90 degrees and pulling it out from the front.

And there you have it, this is a telescoping bolt designed, the bolt is extremely heavy, it doesn’t lock, pretty simple gun all-in-all.

It’s a very high quality gun, I wish these were a little bit more popular.

They are popular in Canada because of Canada’s odd rules regarding magazine capacity.

Long guns can only hold five rounds with limited exceptions.

So those boys have found a crafty way to circumvent this by just getting 10-round Beretta pistol magazines and running them in their CX4’s up there, so.

Special thank you to Ventura Munitions for providing us the ammunition we use in our shooting videos.

We hope you guys enjoyed this field strip, and we hope the see everybody next time.

    I see you’ve upgraded the recoil spring guide rod/link and the buffer with SierraPapa parts. Hammer and trigger upgrades as well? I’ve got those things on my 45 ACP version. It’s a fantastic little carbine.

    I bought my CX4 for the same reasons.

    As always, Beretta makes a sexy, sultry looking weapon.

  • Make sure you load explosive shells if you plan to plink at any frakkin’ toasters.

    On my wish list to Santa……

  • Sean

    I have had mine for 10-12 years. Flawless through tens of thousands of rounds so far.

    Got mine back in 2003 about the time they first came out. Had 10-rd. magazines. Great little carbine, handly, comes along in the car on road trips, goes to ranges outside and indoors, relatively inexpensive centerfire 9mm ammo. Mine was utterly reliable with factory magazines. The only jams I had were when I induced them to practice clearing ’em. But then things got weird and balky and I noticed the metal feed-ramp insert had slipped out. Fortunately, my wife had found the metal piece and asked me about it, so once I got that put back, things returned to normal.

    I’d thought that in the future I’d get one of the old Beretta 92 DAO pistols made for a handful of PDs…. like Tacoma, WA. But I never did. So I’ve got the 92 magazine carbine, but not the pistol.

    The CX4 is a cool little carbine. Unfortunately, they cost about the same as a lower end AR15, but roughly offer the firepower of a Hi-Point carbine. Therefore, I have the AR15, AK47, SKS, and a Hi-Point carbine instead.
    Still, I’d love to pick up one of these someday. They make a great home defense carbine, that anybody can handle (like my wife), and that I’d probably trust more than the Hi-Point.

      if the firepower of a CX4 and Hi-Point carbine are the same… who wouldn’t rather have the CX4?
