"Awesome little gun! The fire rate is really fun and it hits hard! little thing is scary. The build quality is good, not the most awe inspiring but it's built sturdy. It's absolutely a good value for the price I highly recommend! It eats through co2 very quickly however. I will usually get a mag and a half from one cartridge. I will be looking for some green gas mags in the future.

"I received this gun as a mystery open box deal for $99 and... I am glad I spent $99.

I am new to airsoft and only fired 1 magazine worth to see if it worked.

Pros:
Heavy
Metal folding stock
Solid
Select fire
Using the bolt to "cock" the gun, feels smooth

Cons:
None yet

I haven't fielded the gun yet, but I am excited to try it out. I would imagine you would need two to three extra magazines for this gun. I fired a few rounds off in my backyard and was happy about the gun. Also it just feels... awesome.

I have no complaints firing .2 gram BBs.

"To summarize quickly- This gun is a real sleeper, a beast of an airsoft gun.

this gun is so realistic and kicks so abruptly that it is challenging to use, and for me thats what makes it so fun. If you love uzi's then you know the quirks of the uzi's ergos. If youre new to uzis then the first time you pick one up it may surprise you how different it feels compared to basically all other guns. For example, the grip curves to fit right handed users hands, so this gun is definitely not for lefty's. If you're familiar with the uzi's ergos like I am then it'll feel just right.

Accuracy: 7/10 (better than a kwa mac so its good enough)

feel: 9/10 (its plastic but its hardly noticeable and may even be an improvement over a metal version because even in plastic its quite heavy)

recoil: 10/10 (I think its the snappiest blow back Ive ever fired)

efficiency: 3/10 (If you like to load you mags to the real steel equivalency (25 bbs) like me then its not an issue but if you want to fully load the mags to 39 bbs then youre probably going to have a bad time)

reliability/ease of maintenance: 10/10 (When I was a lad I had a friend that had an example that was atleast 10 years old, and it was never lubed or cleaned once and it still worked perfectly. That being said, theyre very easy to take apart, clean and lube)

Fun factor: 10/10

Cool factor: 10/10

Realism: 10/10





Now if this the longer version of my review -

This gun has been around for a long time and for that reason I think its severely underrated.
The earliest mention of the kwc uzi online that I can find was from 2007.
Ive had a huge collection, Ive tried everything from gbls to systema to ghk and this 20 year old design is still my #1 favorite to play with, without question. Mostly because its smaller than an m4, it kicks so hard and because of its cool factor.
I also really like its tunability (rof/fps/amount of kick)

Don't quote me but based on my own experience, I think there are three versions of the kwc mini uzi now.

-the pre 2011 closed bolt version
-the 2011-2023 version with heavier bolt
-The 2022-2023 version with a lighter bolt

The existence pre 2011 closed bolt version is well documented but the two different bolt weights is something I've never seen anyone else mention.


My uzi that came with the heavier bolt has a rate of fire of around 1100 rpm,
my version with the lighter bolt
(which I bought as a boneyard)
is about 1400 rpm
which is so fast it outruns the stock magazine springs. My heavy weight bolt is more gas efficient than the light weight one.
The heavy weight bolt can mag dump 32 rounds without cool down effect but not much more.
The light weight bolt can mag dump only 25 rounds without cool down effect.

You can tell you have the version with the heavier bolt from it having warning labels visible on the bolt, the lighter version does not have that. The heavier bolt kicks quite a bit more aswell. The stock fps with the heavier bolt is around 380 with .20s, and with the lighter bolt its 420 fps with .20s (I ordered a metal 3d printed nozzle to lower the fps so it can be used in game)

Most people think there aren't alot of upgrades but theres actually tons. NPAS type nozzle, different nozzle lengths, a straight trigger, different outer barrels, printed stock adapters, improved gas route, and more.
I DO NOT RECOMMEND THE STEEL BODY KIT as it requires modification to work with the post-2011 version and my steel body actually broke while attempting to assemble it. Not alot of airsoft specific options to add an optic rail on the dust cover but its not rocket science if such a thing is desired and for me, it very much is, as the aperture on the rear sight is hard to see thru with a goggles and mask.

If kwc is going to quietly implement changes to this design then I have some recommendations, first I would make the fps lower, and secondly I would make the trigger out of steel so it doesn't flex left and right. I fixed those issues with a metal 3d printed nozzle and metal 3d printed trigger.

If I were kwc, I would sell the different bolts (and nozzles) separately. Then you could have one bolt for outdoors, and one for indoors, and choose what rate of fire you prefer. Perhaps they could even make a bolt with removable weights so you could really tune your rof.

"I wouldn't want to be on the other end of the this when it goes full auto.

Only con is it eats CO2 if you do (you may go through 1 mag before it's drained). Semi auto you should be able to go through at least 2.

Either way, I recommend grabbing some extra mags.

"i haven't fielded it yet, but this is /the most/ brutal GBB SMG i own. loads of fun to shoot just around the house (LOL not recommended) without BBs loaded))). haven't ever fielded it yet even though i bought it like months ago rofl, but i will some day ~
by TIMOTHY B. on 03/05/2022
"OUTSTANDING!!!!!!!!!!!!!!!!!!!!!! BEAUTIFUL & SEXY. This is what you see in the photo, A super Replica of the Mini Uzi! Its been covered good no dought. The weight,size,and feel is awesome to say the least and the blowback is out of this world! I got a leaking mag with mine, but I called and EVIKE was right there for me! They sent me a new mag very fast, WHAT customer sevice-no equal!!!!!!! You should put this in your arsenal with everything else! This is a great airsoft GUN. (Buy lots of BB's for sure) Tim Bryson Hoorah!!!!!!!

"I love this gun, the sound, the rate of fire, the mag, the weight, the kick, in fact, i ordered a second one for dual wielding , no complaints
by Sean S. on 12/03/2020
"I love this gun, it is exactly how I imagined it being waiting for it to arrive.
It has a realistic weight like the real gun, the magazine feels like a fully loaded 9mm magazine.
The "takedown" is similar to the actual SMG.
I did notice if the gun is on safe don't push hard on the trigger, it can damage the magazines gas nozzle, since it is trying to overcome the safety mechanism. I found that out by accidently thinking it was on "semi," and it started to leak gas after I pulled the trigger too hard and then stopped, I checked the magazine and found a little gouge in the nozzle (pretty dumb of me to say the least). It ran fine though after that, so thank God I don't have to buy a new mag.
It sounds nothing like an airsoft gun. It is quite loud.
I like that it fired from open bolt, like the real SMG.
It also comes with a speed loader that fits over the ears that hold the BB's in place, so it make it's very easy and convenient to load.
What I didn't like is the mag only takes one CO2 cartridge, and runs out of gas in about 2 fully loaded mag uses, so the gas efficiency is really bad and you'll spend a decent amount on Co2 cartridges.
Another thing is the mags are very expensive, about 40 dollars per mag.
Even if you don't play airsoft often or you just like guns it's definitely worth buying if you have the money, due to its similarities to the actual firearm. There is also a .177Cal (4.5mm) Steel BB version.
5/5 I love it, definitely buying from KWC again whenever they have a gun I like.
Most of them are pistols. I have heard you should be careful with their Desert Eagle though.
Each gun they sell comes with a catalog in the package.
Some of the other reviews do have more info than I do, I did make this only a day after having it, so I don't know about any long term issues or wear and tear that may commonly happen over time.

"So I’m pretty sure this is the IWI Uzi now and if so my God it is a beast. The hard kick of the recoil and sound of each shot sounds nothing like an airsoft gun. Most parts are metal, the grip and hand guard are platic, along with the sight/charging handle. But the rest is metal and for a airsoft gun of that size its heavy. The stock is easy to deploy and fold up for both cqb and longer range as it can shoot fairly far for out of the box. Its biggest downfall is the cost of mags, $40 a mag is quite expensive, so unless you wanna invest in this gun and get multiple magazines dont buy. Part of the reason for this is because each mag uses up an entite CO2 canister and towards the end it runs out and the bb’s drop.
My only other complaint at least for myself is switching from auto to semi to safe seems to be a pain and requires some finese.
This gun is worth the price for its quality and realism.
by Marc S. on 01/09/2018
"For the money, this is an extremely well priced, durable, and well made GBB. I bought it primarily as a trainer to supplement real firearms and it serves its purpose well. I've looked at many options and this is probably the best you are going to get at the pricepoint without going for something like the Tippmann M4. Recoil is about the same as a 22LR cartridge which is fantastic. I get on average 60 shots per CO2 cartridge which brings me to a little under a penny per shot, compared to 3-6 cents per shot of 22LR, or 20 cents per shot of 9mm.
For those concerned with realism, the only parts that are plastic that are metal on the real firearm is the outer barrel, receiver/rear trunnion, and trigger (likely also the trigger group). The top cover seems to be aluminum and may actually be surplus parts for real mini uzis as the top is stamped calling it a firearm with the usual markings. The only odd part is that it is non-magnetic (suggesting some kind of aluminum) while the real mini UZI is from steel sheet metal. The bolt is also non-magnetic which I assume is some kind of die cast metal as I can't see any machining marks through the finish.

Issues:
-The recoil causes the muzzle climb to go downward rather than up. This is very subtle and most probably won't notice it but it is noticeable on full auto if you pay attention. Realistically it is inconsequential but if you are used to real firearms it becomes apparent almost immediately.
-The recoil can sting. This sounds silly but it is odd since the recoil on this gun while not as strong as the real 9mm version, some shots can produce usually sharp recoil that can sting the cheek. For those shooting this for airsoft games or force on force and wear a mask, this will not be a problem. However if you intend to shoot this without a mask it will quickly become very unpleasant to shoot. I took a quick trip to the hardware store and bought some foam matting (you can find it where they have cork and rubber sheeting) and cut a 1cmx1cm square strip from the matt and laid it inline on the top of the stock and secured it in place with wrappings of electrical tape. This did not interfere with the complete folding of the stock, but provided enough of a cushion that the sting no longer became painful.
-As most know, this weapon is known to consume a lot of gas for the recoil. One entire CO2 cartridge per magazine is often cited. However there is a bit of a variation depending on how you use this. If you shoot full auto immediately, you are unlikely to shoot all 38 rounds, and often will only get about 25 rounds. To a degree this is fine since the magazines are actually not replicas of 30 round 9mm magazines but of the 25 round magazines. If you load to realistic capacity you will get full performance. However, you can stretch your dollars by shooting on semi auto. If you don't shoot semi auto rapidly, say only 5 rounds per every 10 seconds, you can actually get 2 full mags worth of shots or darn near close to it. When doing up-drills, it is very easy to maintain this slow cadence which is excellent for training. It should also be noted that this is an open bolt firing gun. As a result while inserting a loaded magazines on the bolt closed won't damage anything, it can possibly engage the hammer which will cause you to expel gas prematurely. To avoid this, after every time you dry fire, charge the gun then reload magazines just like a real open bolt SMG. This gun does have a "bolt hold open which is kind of odd compared to the real thing, but all it is is the magazine follower holding the bolt half open, and it drops home when the magazine is pulled out. Personally I don't care for that since when a real firearm open bolt or closed bolt has the bolt only half way in battery, that normally signifies a malfunction, not an empty gun. For those not using this for training it isn't a very big issue. As a side note, one of the benefits is that the thick magazines serve to insulate the cartridges very well so there is little issue with temperature variation.
-The stock doesn't lock, it is held in open or closed position by a detent. This normally is not a problem but the other issue is that the stock buttpad is offset about 1/2" to the right so that it tucks under the handguard when the stock is folded. For this reason when shooting right handed it is possible to accidentally fold the stock a little. This is a relatively minor issue and once you are aware of it it shouldn't happen accidentally. One thing that should be noted is that because of the buttpad offset you cannot install a vertical foregrip in the position where the stock is if you want to allow the stock to fold completely later.
-The iron sights are terrible. On the front sight there is a small plunger which can get stuck when the front sight post is at its highest position (and you will need it at it's highest position because this gun is powerful and makes even 0.2g bbs fly upward like a 0.12g at the lowest hopup setting). The rear sight windage adjustment does not have positive detents and it is more of a friction lock. This isn't really an issue since the windage doesn't drift out of place under recoil, but it is a little disconcerting. The rear iron sights have two apertures of the same size, but on a short and tall post. Again, because of the BBs curving upward even on 0.2g, you will want to only use the short post in order to get as much downward elevation in your zero as possible.

[Note: I wrote a lot about the issues but none of these should dissuade anyone from buying. These are simply little things I noticed that you should be prepared for as a buyer, but they are very minor concerns]

Modifcations
-Anyone who has time using a real UZI knows that the grip safety is terrible. On a handgun it is fine since you acheive a solid grip to shoot, but on a stocked firearm due to the angle of the wrist, rarely is the webbing between your index finger and thumb high and tight on the grip. As a result you can have issues where your gun "locks" on you at the wrong moment. Just like the real firearm, it is advisable to get some electrical tape and wrap it tightly around the top of the grip to securely hold the grip safety depressed.
-Since the iron sights were terrible, I used a drill to widen the aperture of the rear iron sights. This greatly improved light gathering of the sight picture. I also drilled and tapped the top dust cover to accept a small rail section for a mini red dot. This greatly improved the function of this gun and I strongly suggest doing it if you have the basic metal working skills. Even if you don't there are plenty of forums for UZI firearms where they show this modification in detail.
-I also added rail sections to the handguard for a vertical foregrip (just forward of where the buttstock folds) and that bottom rail also serves to mount a SASS style muzzle device mount that I made which holds a tracer unit I made (as the barrel is not threaded). You could theoretically use the barrel nut as a host for mounting a Tracer unit, but I am not certain if the thread pitch is the same as the actual surplus uzi parts available. I also mounted a side rail for a flashlight and wired the pressure pad switch to velcro onto the space just in front of the charging handle which makes it easy to actuate with either side thumb.

Overall this is a fantastic airsoft gun and I recommend it for every use from training, gaming, or just fun. I also advise buying at least 4 spare magazines or you will regret it as you won't want to stop frequently to reload CO2 and BB.

People should be aware that there are apparently kits to modify a magazine to run of HPA or green gas. Considering that you will easily run through a box of CO2 cartridges in a session or two of shooting, I advise considering those kits and I have one on order (from ebay as evike was sold out at the time of my purchase).

"This by far is my favorite airsoft gun. It's loud, it kicks HARD, and it get's people excited. It's such a fun gun. There's really not anything bad about the gun besides how expensive the magazines are that it uses one 12g of CO2 per magazine fired. Overall, awesome gun. If you have the money, but it.
by Jared O. on 12/28/2016
"It's heavy, mean, mighty and tough, not much bad I can say about it other than awful gas consumption, but who cares, the speed loader it comes with is one of the best out of box loaders I've ever had. It eats bbs, lube and gas but it's all worth it when rocking full auto. If you want a nice counter weapon against the try hard, high rps, spray and pray speedsoft queers, then this is you bullet box.
by Dan G. on 07/19/2015
"This UZI ROCKS!!! When I first received it there were some issues; the barrel hadn't been fully seated into trunion (hop-up), and the two halves of the bolt were loose (held together by 2 small allen/hex key screws) causing weird miss-fires, jams and excessive CO2 consumption. After reseating the barrel and tightening the bolt screws, it became an ABSOLUTE BEAST!! I seriously freakin' love this UZI! Yes, it's LOUD & FAST!! (And yes the body + trigger group are plastic, which seems to be very well molded and hi-quality)

BEWARE: the Guarder upgrade parts will NOT work on this version which fires from an open-bolt. They're for the previous closed-bolt version. The bolt & air piston are completely different.
by Evan W. on 05/09/2014
"I got it about a week ago, sawed off the folding stock and taped down the grip-safety with electrical tape. Works great, I get almost two magazines on semi-auto. It's a bit strange, though, the magazine will start to act like it's running out of gas, swap out that magazine, and fire a different one. By the time you're reinserting the old magazine, it's firing like full-charge again, and able to empty those last shots left in it. Very strange, but negligible, considering that it can empty the full magazine anyway without that occurring.

Also, Matt is a liar, or he was misinformed. The entire body of the KWC Mini-UZI is made of an unusually durable plastic, and it feels very nice, despite it being so. Though, all of the internals and key-external parts are constructed of metal.

Make sure that you liberally apply 100% silicon spray on this gun's internals, and everywhere you can get it on the magazine, every nook and cranny. What an excellent GBB, though, it's not as fun as KWC's Desert Eagle, it's miles more reliable than it.

One last word, make sure you buy a lot of Co2 capsules! (Non threaded ones!)
