Today is accuracy day with the Mini UZI CO2 BB Submachine Gun by Cybergun and I have been awaiting this day with great expectations. That’s because almost every owner review I’ve read about this gun emphasizes how accurate it is. Today, we’ll find out.
To be the most accurate BB submachine gun I have tested, this gun will have to beat the EBOS from Umarex that I tested for you in November 2010. That gun was truly phenomenal at 15 feet on full-auto. About 40 full-auto shots could be covered by a half-dollar.
I don’t normally compare guns, but this one time it seems right to do so because we’re talking about accuracy with a BB gun, which is usually nothing special, and other features like firing modes and realism of the guns. So, just this once, I’m relaxing my rules and making comparisons.
And, the Cybergun UZI is coming out looking pretty good. The recoil sensation is so sharp that the wire stock actually stung my face every time I shot the gun. I had to pad it with a shop rag, because at first I thought I had been hit in the cheek by a rebounding BB — it’s that sharp. Holding the gun tight into the shoulder helps a lot, but I think you’ll also need a pad. One of the old jell pads that Pyramyd Air used to sell would work perfectly for this.
Aside from the face slap, that heavy bolt really does jar you when it moves. No other BB submachine gun has a sensation to match this one.
If this was a pellet gun, I would test several different pellets for accuracy, but most BBs are very similar — especially the ones we can buy here in the U.S. I went with Daisy zinc-plated BBs, which were the same ones I used in the velocity test in Part 2.
The first target was shot at the regulation 15 feet and, as I was getting slapped in the face by the wire stock on every shot, I’m afraid my concentration was not at its best. Still, the 10-shot target was very encouraging. In fact, it encouraged me enough to step back two feet so I could use a doorframe as a support to see how much better I could do.
The second target was a real good one, with a group almost as small as the best EBOS group. As you can see, however, the shots are striking the bull a little high, so I adjusted the front sight down four clicks to see what would happen. One more group would tell the story.
This gun has excellent sights. Coupled with the accuracy, which is well above average, those sights can get you on target a lot farther out than 15 feet. I imagine you could roll pop cans at 20 yards with one of these.
The bottom line
I have to give the accuracy edge to the EBOS. It shot the best groups, hands-down.
But for realism and fun, this Cybergun Uzi is hard to beat. I’m glad they didn’t have BB guns like this when I was a kid, because I couldn’t have afforded to keep them in ammo! And, I would have gotten into a lot more trouble than I did.

This gun’s last report had lots of good comments from owners and from those who have been researching it. I think the most powerful feature it has is the fact that it fires from the open bolt. When you shoot, a heavy mass reciprocates in mock recoil. It’s the difference between an M3 grease gun that jumps all over the place when it fires and an HK MP5 that barely recoils at all. This Mini UZI CO2 BB Submachine Gun by Cybergun really jumps around.
I can see why people are impressed by its performance in full-auto. It feels so realistic with that heavy steel bolt working back and forth on every shot.
With the open bolt comes an open receiver, also just like the grease gun. When the gun’s ready to fire, the receiver looks menacingly open and ready for action.
Accuracy is another feature we have yet to test, but everyone who owns the gun praises it for its accuracy. We’ll find out.
Charge the magazine and load
The 12-gram CO2 cartridge fits into the stick magazine, small end first. Don’t forget to put some Crosman Pellgunoil on the tip of each new cartridge before you pierce it. That will be blown through the valve, where it gets on every sealing surface and keeps the gun sealed against gas loss. With it, your gun should last for years. Without it, you may have an early failure.
The BBs are loaded one at a time, with the spring-loaded follower held down with the other hand. It isn’t the easiest thing to do, but it works. I found I could load 26 BBs, despite the manual stating that it holds 25.
Most owners understand that a CO2 gun at this power level will get about 50 shots per cartridge. I tested for this and found that it does get 50 shots, but the last ones are not as fast as the average shots from the first magazine.
They advertise this gun at 344 f.p.s. I tested it with Daisy zinc-plated BBs, which I have found in the past to be the largest and most uniform BB Pyramyd Air carries. In other words, they’re always the fastest. In the test gun, they averaged 350 f.p.s. for 10 shots. The velocity range went from 345 to 357 f.p.s. I was pausing about 10 seconds between each shot for this test, and the temperature was 71 degrees F.
I tested how much velocity is lost by firing very fast. We know that cooling a CO2 gun causes it to shoot slower, and the CO2 is what cools the gun. The faster you shoot each shot, the faster the gun cools down and slows down. To test this, I fired 12 quick shots as fast as I could pull the trigger, then chronographed the next shot. It went 313 f.p.s. That should tell you guys who modify the gun to shoot full-auto what’s going to happen. As you hold down the trigger, you’re going to lose velocity to the tune of about 40 f.p.s. That’s not such a great loss and I think you won’t really notice it.
Another thing I wanted to test was the overall gas consumption. Other owners said they’re getting about two magazines per CO2 cartridge, which would be 50 shots. That sounds about right, given that the gas also has to operate that heavy bolt. I chronographed shot No. 49 at 283 f.p.s. Shot 50 went 269 f.p.s. Because I was able to get 26 BBs in the magazine, I also got shots 51 and 52. Shot 51 was lost, but shot 52 went 231 f.p.s. The gun is definitely out of gas at that point, though the bolt still comes all the way back. To load more BBs and attempt to get a few extra shots is just asking for a jammed BB in the barrel.
I’d forgotten that the gun has a grip safety but was reminded when I started shooting it. Also, it didn’t register that I had to cock the bolt for the first shot. Since we had a question about how you can see the sights with that fat knob in the way (the cocking knob), I’m showing it here, so you can see the wide slot cut through the center.
Rating so far
It’s difficult to remember the other BB submachine guns at this point in time, but I think I can safely say this one has the most realistic feeling recoil. That heavy bolt really rocks the gun when it moves. I do like the grip safety, and even the trigger seems pretty crisp and positive for this type of BB gun. Although there are a few plastic parts on the outside of the gun, this is a very heavy airgun that gives a solid sense when you shoot it. If it’s as accurate as the owners say, it’ll be a winner in my book.

Let’s take a look at the Mini UZI CO2 BB Submachine Gun from Cybergun. What we have here is a steel BB-shooting gun made and packaged by an airsoft manufacturer and sold by distributors. Everything (the gun, box, owner’s manual, etc.) is made in the style of airsoft guns, not airguns. I even found the gun itself called a “Softair” in the instructions, which look exactly like other airsoft manuals, so there isn’t much doubt where the gun comes from.
I was surprised when I was reviewing the other BB submachine guns that no one asked why I wasn’t testing this one as well. I guess it’s just flying under the radar at the moment.
The other BB submachine guns
Here are the BB submachine guns we have looked at thus far in this blog. First was the Russian-made IZH Drozd that we looked at here. I also did another report on it here. Then, I tested the EBOS from Umarex. The reports on that gun are here. And let’s not forget the H&K MP5 PDW gun. That one was covered here. And, of course, we also looked at the Umarex Steel Storm. That report can be found here.
We’ve looked at four BB submachine guns to this point. This Mini Uzi is number five. The gun is really a pistol-sized gun, as most submachine guns are. Though small, at just 14 inches overall, the gun weighs 4.85 lbs., which makes it a real chunk. What isn’t as clear from the description online is the presence of the folding wire stock that increases the length to 23-1/2 inches and gives you a more-than-generous pull of 15-7/8 inches. While I’ve never fired an Uzi, I have shot enough 9mm HK MP5s to know that you don’t shoot them from the hip if you expect to hit anything. These modern submachine guns all have good sights and are meant to hit targets out beyond 25 yards, so the rifle stock comes in quite handy.
This gun comes to you in semiautomatic, only. There’s a three-position selector switch on the left side, but the A for automatic is a non-functioning setting. You cannot slide the selector switch over to the A. You just have R for semi-auto and S for safe. However, there’s a way to make the gun full-auto.
Yes, with a small modification, it’s possible to make this gun full auto. It does require some disassembly and any parts modification that you would do (and you must modify the gun for it to be full-auto capable) voids your warranty. Since I’m going to return this gun to Pyramyd Air, I won’t be modifying it. If you’re interested, you can find out how to modify the gun online, but bear in mind that the warranty will be voided.
The gun is powered by one 12-gram CO2 cartridge that fits in the bottom of the stick magazine. The magazine also holds 25 BBs under spring pressure, and I’ll report to you about the feeding reliability when I write the velocity test.
Some unusual features
Now for some things you don’t see on other BB guns. The first is a grip safety that blocks the trigger until squeezed by holding the grip. These safeties make guns safe in situations…like when they fall to the ground, which tactical guns will do from time to time. They also make it harder for bad guys to shoot you with your own gun while you’re holding it.
The other strange feature is going to make me look like a fool, but I really haven’t figured it out yet. There’s a heavy steel collar around the barrel that has a ratcheting mechanism with a positive lock. Inside the mechanism, there’s a coiled spring. But what it does is anyone’s guess. It might be threads for a silencer. If so, why all the extra parts and complexity? The barrel shroud moves when this collar is loose and not when it’s tight. The manual doesn’t address it, so I guess I’l just have to figure it out as we go.
The folding stock has no positive lock for either position. There’s just a spring-loaded detent that holds it wherever it is. It presents no problem as a BB gun stock, of course, but many owners may want a locking stock like the firearm.
Owners love it
I read the reviews of this gun on the Pyramyd Air site, and the thing people like the most is the realistic blowback recoil simulation. The bolt is heavy, and apparently the gun feels delightfully realistic when fired.
A second thing most owners commented on was the accuracy of the gun. With the four reviews listed of the other BB submachine guns above, the Mini Uzi will be up against some stiff competition, but a look at this gun’s sights tells me that, whoever made it, they were thinking about hitting the target.
The one drawback seems to be an excessive use of gas, however, it isn’t as bad as it sounds. One owner said he thought he was getting about two magazines worth of shots per cartridge. That would be 50 shots. With the blowback feature that also uses some gas, that’s about right. It’s just that this gun makes you want to shoot-’em-up so much that you’re blowing through the gas that fast.
The sights are an aperture rear and post front, and they’re both adjustable. The front sight adjusts for elevation and the rear for windage. The front sight uses the same positive spring-loaded pin lock found on an M-16. I hate adjusting this type of front sight system because it’s so cumbersome; but once it’s dialed-in, it never changes. There ‘s a tool in the box for this, so you don’t need to carry a 5.56mm cartridge in your pocket — but it’s still difficult to adjust.
Anyone with M-16 experience will recognize how this sight is adjusted. Press down on the spring-loaded pin and turn the sight base in the correct direction. A special tool is provided with the gun for this. Note the front sling swivel stud on the left of the sight ear.
The rear sight is an L-shaped leaf with two different apertures, one large for rapid target acquisition and the other smaller for precision. A screw on the left side of the assembly moves the leaf from side to side, and of course you adjust it in the direction you want the pellet to go. The aperture rear sight is a no-brainer sight, which is why most of the world’s military uses them. Just look through the rear hole and position the front post where you want to BB to go — it’s that simple.
Finally, the gun comes with sling swivel studs front and rear (the bottom of the stock hinge pin has a hole, and there’s another anchor on the left side of the frame at the front sight). This comes from the firearm, of course, and from the airsoft heritage. As heavy as the gun is, a tactical sling would be a nice touch.
The advertised velocity (344 f.p.s.) is fast, but not blistering. I like that because, frankly, when steel BBs get up around 500 f.p.s., they get hard to manage downrange. Since you can’t hunt with BBs anyway, this velocity is right where it needs to be and the blowback feature doesn’t have to use up that many shots.
This is a heavy gun that feels substantial. Yes, there’s plastic here and there, but most guns made today have some somewhere. The customer comments are quite reassuring, making me want to rush into this test faster than usual.
