Type: Nerf Type Gun. Manufacturer: Umarex Model:REKT OPFOUR. Materials: Mostly plastic build with some internal metal parts. Weight: 1 pound 8 oz (680 grams). Length: 30 inches (762mm). Propulsion: 12 gram CO2 x2. Action: Pump single action. Ammunition Type: Nerf type foam darts. Ammunition Capacity: 12 rounds. Max FPS: NA. Claimed 30% faster and 30% father than standard similar type Nerf spring pistols.
Trigger Pull: The trigger on the Umarex REKT OPFOUR CO2 Foam Dart Rifle is what you would expect form a single action only trigger. Very little take up with a crisp light release. When you pull the Free Grip back you are working the pump action which loads a dart into the breach and at the same time cocks the internal hammer/striker.
Accuracy: I haven’t performed my Field Test Shooting video for the Umarex REKT OPFOUR CO2 Foam Dart Rifle but I can say after play around with it I expect it to shoot a lot harder than 90 fps. When the dual CO2 system is fully charged I was getting some pretty ferociously fast shots form the Umarex REKT OPFOUR CO2 Foam Dart Rifle. I would say it was even able to shoot out into my yard at least 150+ feet. I was even a bit concerned shooting the Umarex REKT OPFOUR CO2 Foam Dart Rifle inside my house as it is possible to dent walls with the Nerf Darts. IN terms of accuracy it seems pretty good but I will know more once I have made my Field Test Shooting Video later this week.
Build Quality: The Umarex REKT OPFOUR CO2 Foam Dart Rifle is built pretty much exactly like other Umarex all plastic CO2 BB guns and that’s a good thing since they are pretty much bullet proof. I would even go on record to say the Umarex REKT OPFOUR CO2 Foam Dart Rifle is built better or should I say stronger than a Standard Nerf gun in terms of plastic thickness and even the fit and finish is very good.
Realism: One big advantage over most Nerf Guns is that the Umarex REKT OPFOUR CO2 Foam Dart Rifle looks a lot more like a real gun, it’s about the same size, has the same feel and looks a lot like a modern AR Rilfe other than the bright coloring going on. Ergonomically speaking the Umarex REKT OPFOUR CO2 Foam Dart Rifle would make a much better trainer than a Nerf gun since it is close to a one to one scale replica.
Pros:
No need to work a spring before each shot because of the CO2 power source.
More power and range than a traditional Nerf Gun.
More realistic looking than most Nerf Gun.
Like an Airsoft Gun but more usable indoors and less chance of injury.
Rear Peep sight is removable and can be swapped out.
Has a working selector switch safety.
Uses Standard Nerf Foam Darts.
Picatinny Rail top and sides for adding on accessories.
Dual CO2 system for extended shooting time before changing.
A great option for having some indoor fun!
Cons:
Will require CO2 x2.
May actually be a bit too powerful and can cause damage or injury if not careful?
More money than a traditional similar type Nerf rifles.
Comments: The Umarex REKT OPFOUR CO2 Foam Dart Rifle may be the ideal indoor fun Nerf styled rifle right now while we are all staying at home a lot more these days. Sure you could use a standard Nerf Gun but having a CO2 powered AR-15 looking Nerf gun is way cooler! I like that the Umarex REKT OPFOUR CO2 Foam Dart Rifle is more realistic looking then a traditional Nerf Gun, perhaps the perfect intermediary gun if you want something between a Nerf Gun and an Airsoft Gun? If you’re interested in a pistol version of the REKT line of Nerf Dart shooting guns then checkout the REKT OPSIX.
My Table Top Review for the REKT OPSIX CO2 Single Shot Foam Dart Launcher:
As always Crosman delivered again this year with some new Airgun products to show us. In this Velocity Outdoors SHOT Show 2020 Las Vegas Interview we take a look at three main standouts for me. The Crosman Full Auto R1 AR CO2 BB Rifle, the Crosman Full Auto P1 CO2 Blowback BB Pistol and something a lot different, the Havoc Prime Spring Powered Foam Dart Blaster.
The Crosman Full Auto R1 AR CO2 BB Rifle is a hybrid of the DPMS SBR and the PDW form past years with a focus on bringing the Crosman name to their own more true to form AR style rifle. You still get interchangeable but stocks and pistol grips if you want to swap them out for a different AR type. The Crosman Full Auto R1 AR CO2 BB Rifle has a longer accessory rail with a more traditional muzzle break. The R1 also comes standard with a red dot sight.
Velocity Outdoors also introduced the Crosman Full Auto P1 CO2 Blowback BB Pistol with select fire semi and full auto modes. The Crosman Full Auto P1 CO2 Blowback BB Pistol is essentially a KWC Taurus with the addition of a really nice laser sight.
One little treat that I think will be popular as a fun indroor shooter is the Havoc Prime Spring Powered Foam Dart Blaster. Unlike traditional Nerf guns the Havoc Prime Spring Powered Foam Dart Blaster actually shoots upwards to 130 feet per second and is super accurate with its rifled barrel. The ammo even looks like a 9mm round but not so deadly :) A Big thanks to Phillip from Velocity Outdoor for allowing us they interview him again this year!
Here we go again, another round of SHOT Show videos brought to you direct from Replica Airguns!
As always I like to start off with a Teaser Video with a few quick clips of some of the new products I had the opportunity to take a look at at this years SHOT Show 2020 Las Vegas.
I will be rolling out Interview Videos as quickly as I can edit them and put them together for the following Airgun Related companies:
Sig Sauer
Umarex
Crosman - Velocity Outdoors
ASG
Air Venturi
Chiappa
So sit back and enjoy this years Replica Airguns SHOT Show 2020 Las Vegas Teaser Video!
There has been some confusion when it comes to the KWC made Mini UZI regarding semi and full auto abilities and also when it comes to build materials. But before we get into that if you have one of these Mini UZI Blowback BB or Airsoft guns then most likely yours is made by KWC even if it was distributed through RWS, Umarex, Gletcher, Cybergun or some other company. When it comes to the build materials used they are all made by KWC so they are all built the same with plastic and metal in the same places.
Let’s first talk about why some of these Mini UZI’s only come in semi auto with the Full auto selection not available out of the box. This is most likely because in some countries a full auto BB and/or Airsoft gun can be illegal so to play it safe many airguns that are originally made to shoot in both semi and full auto are modified to only shoot full auto. This is the case with most of the companies that redistribute the KWC Mini UZI under their own brand name. That said if you buy the KWC Mini UZI in either 4.5.mm Steel BB or 6mm Plastic Airsoft from our Replica Airguns Canada or US Online Stores, you will be getting a full auto ready out of the box airgun!
If your MINI UZI Airgun is not full auto ready then checkout my Full Auto Mod Video but make sure before you do this modification it is legal in your country to do so or you could be looking at jail time :(
When it comes to build materials the KWC Mini UZI is often described on websites as being full metal which is close but not entirely true. It is accepted that most full metal airguns will have plastic grips but the KWC Mini UZI also has a plastic shroud around the main receiver that is am all in one piece that makes o=up the front and back sights. This might lead you to think that the gun is mainly plastic which is far from the case since all other parts like the receiver block, bolt, top plate, barrel, rear stock, trigger and magazine are metal. This give the KWC Mini UZI its sold 4.8 pound weight. The heavy metal internal bolt really makes this blowback airgun rock when you shoot it simulating very close recoil action to a 22LR. The KWC Mini UZI for sure has the most blowback recoil out there.
If you are looking for the most bad ass and action packed full auto BB or Airsoft Gun then I would highly suggest you consider getting one of these KWC Mini UZI’s. Just be sure to have lots of CO2 and BB’s on hand because you will go through both like crazy…
I usually do my Table Top Video Review first but in this case I decided to pump out my Field Test Shooting video ahead of it. So if you're looking for more detailed specifications then just wait a bit till I get my Table Top Review out. What you really need to know about the Umarex Morph 3X CO2 BB Gun is that it's a CO2 4.5mm BB Gun with a 30 round internal magazine sporting multiple configurations as the stock, barrel and forward stock are all removable so it can be a pistol or a rifle and many variations in-between, even more than 3X of them.
The US version of the Morph 3X CO2 BB Gun when installing the rifled barrel (Which is not rifled buy the way), will shoot faster than when the Morph 3X CO2 BB Gun is in pistol version since the add on barrel adds a lot of additional barrel length to the airgun. The Canadian version which I am testing does come with the extension rifle barrel but it is only for show as the inside is missing the 4.5mm inner barrel. This is because our Canadian import laws for uncontrolled firearms would not allow the rifle version of the Morph 3X CO2 BB Gun here in Canada as it would potentially shoot with too much fps (around 600 fps) and foot pounds of energy for our Canadian non regulated gun laws. As it stand the Canadian version of the Morph 3X CO2 BB Gun has an fps rating of 480 fps in both pistol and rifle configurations.
All that aside how did the Morph 3X CO2 BB Gun do during my testing? Awesome to be precise! It actually averaged a 5 shot Chronograph Velocity Test of 498 fps even in pistol configuration which is very impressive for a CO 2 BB gun. I also was able to get the majority of my 10 shots on a paper target positioned 30 feet away from me using a rested seated position within about 3/4 of an inch. I even played around a bit with holding the Morph 3X CO2 BB Gun out in front like a pistol and tight to my shoulder using the rear stock.
It's kind of too bad we don't have the inner rifled version here in Canada as even at 600 fps we are just under 4.2 foot pound Canadian limit but trying to explain that this is still OK to our CBSA border guards is just a little too much for them to process :) Even without the inner barrel the Morph 3X CO2 BB Gun is a really great and super versitile airgun with lots of power and just as good accuracy!
Type: Nerf Gun. Manufacturer: Nerf Hasbro Model:Rival Zeus MXV-1200. Materials: Mostly plastic build. Weight: About 3 pounds with batteries installed. Ages: 14+ (My son is 10 and he is more than OK with this gun!) Propulsion: Electric flywheel 6x C batteries. Action: Semi auto. Ammunition Type: Nerf High-impact round balls. Ammunition Capacity: 12 round tube magazine. Max FPS: 100.
Trigger Pull: The trigger on the Nerf Rival Zeus MXV-1200 is a little long and requires a firm trigger finger but it is not overly heavy. When you press the trigger it allows a Nerf High-impact round ball to advance into the motorized spinning flywheel area where the ball is accelerated and shot out of the inline barrel .
Accuracy: Keep in mind the Nerf Rival Zeus MXV-1200 is designed as a fun in home battle gun so long range accuracy is not really that important. At up to 30 feet or so you shoudl have no problem hitting a person sized target. The Nerf High-impact round balls do come out the the barrel with a fair amount of spin so some random hooking can happen, usually the spin is more of a backspin that helps keep the ammo targeting in a more linear trajectory.
Build Quality: The Nerf Rival Zeus MXV-1200 like most Nerf guns is built to take a fair bit of a beating since the target audience has mainly been kids and we know they are rarely careful with anything ;) The Nerf Rival Zeus MXV-1200 is mainly plastic but as I mentioned it is high quality and so far has held up well to usage. Fit is good with all interchangeable parts working well and the finish has stayed pretty much pristine!
Realism: Nerf guns are not made to be too realistic since they are meant to be toys and not look too closely like a real gun, hence the brightly colored plastic and more futuristic design. I do like the addition of Picatinny styled rails in several locations where one can add accessories like magazine clips, red dots or even a tactical light or laser sight.
Pros:
Not as extreme as a Paintball gun but a little more intense than a standard Nerf gun.
Good build quality overall.
Easy to quickly swap out a fresh 12 rode tube magazine.
Flip up sights
Picatinny raise for adding accessories.
Decent power and accuracy for a Nerf style gun.
Semit auto action for fast follow up shots.
Cons:
Will use up batteries pretty quickly.
Flywheel will slow down when shooting close together semi auto shots.
Loading magazines does take some getting use to.
Comments: The Nerf Rival Zeus MXV-1200 is a great option for pretty much anyone looking for a fun battle gun you can use indoors in your home with no worries about breaking windows or messing up your house. not to mention leaving west all over your body! The Nerf Rival Zeus MXV-1200 is going to be a bit more extreme than a standard Nerf gun for sure but way more toned down compares to a paintball gun or even an airsoft gun so if you want some good old rainy day indoor fun then checkout the Nerf Rival line of Nerf guns.
My Vimeo Table Top Full Review for the Nerf Rival Zeus MXV-1200:
Well ANT (Advanced Novelty Tech) made an update model that supports a bunch more guns, that's a good thing of course. This new model is called the "FIRE" and it supports the following guns. I did find however that ANT list that the Gletcher NGT and Webley Mark VI Revolvers where supported by the FIRE but my findings indicated the CO2 screw on both these guns had a smaller diameter so they where not compatible. Other than that small discrepancy most of the other guns on their list should work just fine.
What exactly is the ANT Advanced Novelty Tech FIRE CO2 HPA Conversion Kit?
The Advanced Novelty Tech FIRE CO2/HPA Conversion Kit is a remote line adapter for Airsoft, BB, and pellet guns. Compatible with over 60 guns, it is easy to install and converts a compatible gun for use with a Paintball remote line and CO2 or HPA tank. Eliminating the need for disposable CO2 cartridges, while still being interchangeable with disposable CO2 cartridges, it delivers a longer, more powerful, and more consistent shooting experience between refills.
So what is the ANT Advanced Novelty Tech FIRE CO2 HPA Conversion Kit going to do for you?
Eliminate the need for the more expensive disposable 12 gram CO2 cartridges.
Use interchangeably with disposable 12 gram CO2 cartridges.
Use in conjunction with a Paintball remote line with standard quick disconnect fittings and a CO2 or HPA tank. (recommended use up to 1000 psi)
Shoot thousands of rounds before needing to refill your CO2.
Fits compatible Airsoft, BB, and pellet gun CO2 pistols.
Easy drop-in installation.
Overall cost savings.
More consistent FPS especially when shooting fast or in full auto.
I am showcasing here on the Replica Airguns website and over on the Replica Airguns YouTube channel a series of videos I am making for the purpose of selling some guns out of my personal collection. I simply have no more room for the new guns and in some cases I either have duplicate guns or very similar versions so there is no need to have both. Some guns I am less attached to and as I already stated I need to make room for some of the new stuff I will be reviewing and or buying for myself.
In this third Mike's Personal Guns For Sale video I am offering four BB rifles, three of which have full auto or at least burst mode ability and the fourth BB rifles is more of a Shotguns with the ability to shoot three BB's at once. Most of these BB rifles are really hard to get here in Canada now since one is not made anymore and the two are simply not currently being imported into Canada.
Make sure to watch my above YouTube video to see these four BB rifles I am selling and instructions on how you can take part in the sale and purchase of them. By the way I am only selling to Canadian residents since shipping cross borders is a little sketchy.
Here is a list of the BB Rifles I am selling from my personal gun collection:
With the popularity of the KWC - Cybergun 1911 Blowback CO2 Pistols and how super realistic they are in so many ways, it is no surprise that people often ask me if they can replace the original grips with grips made for a real 1911.
The short answer is yes you can! You will have to be prepared to remove just a little bit of material from the backside of both grips near the bottom of the handle where there is an area that has been flared out to accommodate the CO2. Not really a big deal, you can use a Dremel for the quick and easy approach or even some sand paper if you don't mind taking a little more time.
While the weather is still nice, I decided to setup some clay pigeon targets at varying further out ranges than the typically 30 feet I shoot on my deck. So I figured 40-60-80-100 foot ranges would be a good test to see if a 4.5mm Steel BB rifle could effectively hit targets at any of these ranges.
I did do a similar test earlier on using my Umarex Steel Force but I think the Steel Force may have been a bit underpowered for the 80-100 foot shots.
So today I brought out my Drozd Blackbird since it has a bit of power and what it may lack in accuracy it for sure makes up in volume! As with many of my shooting videos I captured all the fun using a bunch of different cameras and camera angles and today I even wore a dedicated lapel mic which I have a min-review for coming up shortly!
So make sure to watch my YouTube video and see how the Baikal Drozd Blackbird does shooting clay pigeons up to 100 feet away...
You guessed it, another Full Auto Fun YouTube Video! And another great Blowback BB gun from the past dusted off and brought out for some more shooting fun :)
With that said this video is me actually shooting my original Cybergun / KWC Licensed GSG 92 version that I modded to shoot full auto. It was giving me a bit of trouble today but it seemed to work out the kinks near the end.
In an upcoming Full Auto Fun Video I do plan to bring out a new KWC full auto ready M92 and Mini UZI to see how these factory full auto 4.5mm BB guns shoot out of the box.
I do have to say, modifying the PPK to Full Auto is not recommended, mine originally worked well but the heavy blowback in full auto eventually broke the firing pin setup and I lost it somewhere in my back field. I had to Macgyver a bolt in place to kind of work but now my Full Auto Modded PPK shoots out of control, what I mean by this is when I press the trigger, it does not stop shooting until all the BB's are gone. Safe, I don't think so!
My suggestion is to leave the Umarex Walther PPK as is, it truly is a an awesome CO2 Blowback BB replica with some really decent blowback recoil in a small airgun.
Full Auto Fun video number three this week and this one is perhaps the craziest one! When you take a Drozd Blackbird that already has a 800-1000 round BB magazine, convert it to 1200 rounds of full auto, add a custom JimC Barrel to it, some bulk CO2 and a bunch of other cosmetic accessories... Well you get the most ridiculous full auto BB gun you can ask for.
Since I had an extra 800-900 BB's more than I am used to when making these full auto videos, I decided to add a few additional targets over and above the clay pigeons I have been using so far. I picked up a nice fairly heavy gauge Santa tin and a rather solid hard wax candle from the dollar store that proved to add some drama to this Full Auto Fun video!
Make sure to also watch my first two Full Auto Fun videos:
If you like what you see in this video and want an absolutely crazy BB gun, then checkout our Replica Airguns Store where we Sell the Drozd BB gun and some add ons for it!
This "Full Auto Fun" video focuses on my KWC/Cybergun 4.5mm Steel BB CO2 Blowback Mini UZI BB Gun, where I kick of a short series based around shooting a bunch of 4.5mm Steel BB machine guns! Sounds like fun cause it is fun!
This KWC/Cybergun Blowback Mini UZI comes in a variety of versions, 4.5mm Steel BB and Airsoft versions, it also comes in RWS and KWC Distributed models.
In this video I basically shoot a bunch of clay pigeons positioned in various locations and film it using 4 different camera angles to spice things up a bit.
I also mention some upcoming videos where I will be shooting my RAP4 MP5 and Baikal Drozd Blackbird Full Auto BB guns so make sure to watch those video when I upload them later on this week!
In this "head to head to head" pistol shootout I compare three of my more powerful, or you could say effective air pistols against each other. Shooting at some pop cans from about 30 feet away to see how destructive each one is. I don't generally recommend air pistols for pest control simply because they tend to be less accurate and powerful than rifles, especially out at the longer ranges where a magnified scope is required and notably where the pesky vermin like to hang out.
I would have to say out of the three tested in this video comparison, the Webley Alecto in .22 caliber and the Modified Drozd Full Auto BB Gun would for sure get the job done at closer ranges. The Webley Alecto simply because it can hurl a heavy grain .22 caliber lead pellet right around the 500 fps mark which will take down small pests, again at close ranges.
My second choice or even first choice depending on how active the pest are would be my modified full auto 1200 rounds per minute Drozd that hurls 4.5mm Steel BB's at over 500 fps (under 4.2 foot pounds) at a rate of 20 BB's per second! A 4.5mm Steel BB traveling at 500 fps will penetrate fur and feathers very well and with most of the 20 BB's hitting a target in a matter of 1 second, that is going to humanly put a small to even medium sized pest down for sure. And yes the Drozd becomes a pistol when yuo take the rear stock off ;)
My last choice for the job is the Xisico XSP180 in .177 caliber since like the Webley Alecto it is only a single shot, so you got to make it count and being that it has less overall energy than the Webley Alecto again I would prefer the Alecto over the XSP180.
Watch my "head to head to head" Vimeo video to see how these three pellet pistols compare:
Another quick revisit of the KWC/Cybergun M92 Beretta - Taurus full metal, full blowback, CO2 4.5mm Steel BB pistol series. They come in several flavors but are all made by KWC and in many cases redistributed licensed by Cybergun. This Field Test Shooting Video Review focuses on the Cybergun Swiss Arms P92 version.
Now that I have a more standardized Field Test Shooting format, I though I would revisit this series of KWC/Cybergun Beretta - Taurus Replica BB Pistols and do a follow up Field Test to get some more camera angles and hopefully a nice tight target grouping using my standard semi rested position from 20 feet away.
I also incorporate some high speed video near the end of this Field Test Shooting video Review to go along with the Chronograph and target portion of the Filed Test Shooting review.
The KWC - Cybergun Full Blowback All metal serious of Replica CO2 BB Pistols has been hugely popular over here at Replica Airguns and for good reason, they are very realistic in looks and operation, are priced very respectably and replicate several of the more popular semi auto pistols.
Action: Semi auto, double action only with blowback.
Ammunition Type: 6mm plastic Airsoft BB's.
Ammunition Capacity: 15 round stick magazine.
FPS: 380.
Trigger Pull: The Double Action Only trigger pull on the Umarex Walther P99 CO2 Blowback Airsoft Pistol is long but not overly heavy for a double action trigger, it does have a break point mid way where it locks partway back, I presume this is the point in which a BB is loaded from the magazine into the barrel? The rest of the pull is still medium but much shorter with a distinct release point.
Accuracy: I did do a quick preliminary test before I made this table top review to get an idea of where this gun performs in terms of FPS and accuracy, I shot 5 rounds through my Chronograph on a fresh CO2 and got an average of 333FPS which was a bit lower than the claimed 380 but it was not the hottest of days. I also stepped back 20 feet and from a semi rested position I was able to get 9 shots within 2 inches of each other which was not bad for a DAO gun that I have never shot before. I did shoot a bit down and to the left with the set sights.
Build Quality: The Umarex Walther P99 is well built for its rather low price tag, it may not have all the bells and whistles but it does get the job done with good fit and finish and materials used. You will find a plastic/polymer frame but there is a lot of metal where it would normally be found on the real steel version like in the slide, magazine, trigger, slide catch, magazine release, inner barrel and many other internal parts. No real complaints here!
Realism: The Umarex Walther P99 CO2 Blowback Airsoft Pistol is pretty close in looks to a real steel Walther P99 with the exception of a missing decocker, but I'm pretty sure this is the same with the real steel DAO version? There is also the funny looking safety on the right side of the frame found on many Umarex airguns. I have to mention the red tip but again this can be removed and even when removed the barrel it is still recessed which adds to the realism. The Blowback action, Walther licensing and nice heavy weight all add up to make this Airsoft pistol look and feel the part.
Metal slide and internal parts gives it decent weight.
Rail for accessories.
Well hidden CO2 screw.
Walther licensing.
Recessed inner barrel.
White dot sights, easy to use.
Right amount of power for indoor CQB style airsoft games.
Cons:
Comes with a red tip even in Canada.
Double action only, so trigger is a bit heavier.
Kind of funny safety, not like the real gun.
Blowback was a bit sluggish.
Comments:
Overall the Umarex Walther P99 CO2 Blowback Airsoft Pistol is a very good buy, it's a decent replica of the real steel Walther P99 with blowback operation, lots of metal parts, good fit and finish, decent performance and full Walther licensing and trademarks. All at a very affordable price tag. It may lack some of the extras you will find on more expensive and more functional Airsoft pistols but the simplicity of the Umarex Walther P99 CO2 Blowback Airsoft Pistol means it will most likely be a bit more reliable with less to go wrong down the road. If you have been looking for a nice Walther styled replica in an Airsoft version this may be just be the ticket!
My Vimeo Video Review for the Umarex Walther P99 CO2 Blowback Airsoft Pistol:
I will be doing proper Table Top and Field Test Videos for each of these Airsoft guns as soon as I can get to them all, starting with the Umarex Gas Blowback H&K MP7 A1 Airsoft PDW so stay posted for these upcoming video reviews...
After many many requests to show how the Umarex Walther PPK CO2 Tab Modification is done I have relented to public demand. I don't actually cut my tab in this PPK CO2 Tab Modification Video but I do go step-by-step in detail and compare my modified Umarex PPK to my unmodified Umarex PPK. It is really very basic on how this is done and only a hack say and perhaps a file are all that is required to make the modifications to the PPK CO2 tab in order to make it flush with the bottom of the handle area.
Your best bet is to simply watch my YouTube Video located below and follow the steps there but here it is in text form:
Place an empty (already pierced) CO2 into your Umarex Walther PPK and tighten the unmodified CO2 tab until fully tightened, just like you would tighten a fresh CO2.
Take note at how many threads are exposed between the bottom of the handle and the top of the plastic CO2 tab, there should be about 2-4 threads exposed.
Unscrew the CO2 tab all the way, place the PPK BB Pistol so it is secure (in a vice of some sort) and use a hacksaw or dremel to shorten the CO2 screw just above the plastic tab at the thread location you previously noted. Be conservative as you can always cut or file the screw a bit shorter if your first cut was not short enough.
Now use the same hacksaw or dremel to cut a notch in the exposed cut area of the CO2 screw so that you can use a slot screwdriver to tighten the CO2 screw.
That's it - Enjoy your modified Umarex Walther PPK CO2 BB Pistol!
Watch my Vimeo Video of the Umarex Walther PPK CO2 Tab Modification Tutorial:
This is not meant to be a full review of either the BB or Airsoft version of the Cybergun - KWC CO2 Blowback Mini UZI's but I do talk about specifications, show you around both guns, and put them both through a full Field Test so I guess in a way, perhaps it can be considered to be a full review ;)
I will list the specifications here for you but I am not going to get into details like Trigger Pull, Build Quality, Accuracy and Realism. You can check out my other video reviews for more information on the Mini UZI:
As I said you can check out all my other videos for info on these very accurate Mini UZI Replicas, I mainly want to go over some of the main differences and similarities for both the BB and Airsoft versions.
In terms of build quality they are made almost exactly the same and weigh in at a hefty near 5 pounds, the only differences are the inner barrel and magazines to accommodate the different sized ammo. The BB version has a 25 round single stack magazine that does not have a follower to stop the bolt from continuing to operate even after the magazine is empty. While the 6mm Airsoft version has a double stack magazine that holds 38 rounds and does have a follower to stop the bolt which can save you some unintentional wasted CO2.
The Airsoft Mini UZI version is distributed by KWC while the 4.5mm BB version is distributed by Cybergun, you will find the UZI and IWI licensing on the Cybergun 4.5mm BB version but not on the KWC 6mm Airsoft version.
Out of the box the KWC Airsoft Mini UZI is ready to go in both semi auto and full auto while the 4.5mm steel BB version will only shoot in semi auto mode, it can however be easily modded to shoot in full auto.
Both guns come in cardboard boxes with manuals, some BB's and an Allen key to tighten the CO2. The KWC Airsoft Mini UZI also comes with a handy speed loader.
There is a slight fps velocity difference between the two with the KWC Airsoft 6mm plastic rounds traveling at around 400 fps (with .20 gram BB's) and the 4.5mm Steel BB's traveling at right around 350 fps. In the field test portion I test both guns out on some water filled cans to see how each ammo type performs in terms of penetration.
Your best bet is to watch both my Table Top and Field Test Comparison Video Reviews and see for yourself how they compare!
