Every once in a while something goes wrong and your favorite BB shooter stops working as it should :( One of the most common problems I see with many of the full blowback BB and Airsoft pistols are BB's getting stuck in the gas tube. This is because this style of gun loads a BB into the breach area of the barrel every time you rack the slide forward. Of course this is only when there are BB's in the magazine.

The semi auto style of these guns is similar to that of a real gun, the blowback operates the slide which in turn moves back and then forward and loads a BB into the chamber. With a real gun, if you where to rack the slide manually again without shooting it, the chambered round would be ejected by the extractor but with a BB gun there is no extractor because there is no spent shell to eject. So multiple BB's can be loaded into the chamber area of the barrel overloading it and if the BB's have nowhere to go they just jam up and often go back into the gas tube which can cause all kinds of problems...

In this Cybergun KWC Tanfoglio Witness 1911 Stuck BB Removal Tutorial Video, I show you how to remove a BB or even multiple BB's from the gas tube area which in short requires; the removal of the slide and guid rod and spring so that you can push the gas tube forward and shake the BB out of the front of the gas tube.

Watch my Vimeo Video on how to remove a stuck BB from the Gas Tube on my Tanfoglio Witness 1911.

I have not done my official Table Top and Shooting Reviews for the Gas Blowback Airsoft Cybergun Sig Sauer P226 but I really wanted to cut off the ugly orange painted barrel tip, it was kind of driving me crazy! keep in mind here in Canada we are not required to have orange tips on our Airsoft guns, most of the all metal or all black Airsoft guns imported these days fall into the "airgun uncontrolled firearms" category. If you live in the US or other parts of the world you could be breaking the law if you do this mod so be warned...

Your best best is to simply watch my Vimeo Video as I show you exactly how I removed the orange painted portion of the metal barrel using a hack saw, file, vice and some sand paper. All in all it was not too difficult and only took about 15 minutes to complete...

I have been asked so many times to make a "How To Video" on cleaning Airguns and Blank Guns so I thought I better make the video so people stop asking me to make one :) and if they do ask, which I am sure they still will, then I will be able to direct them to this awesome video tutorial...

So basically in this video I clean an Airgun that can be field stripped and I also clean an Airgun that can not easily be field stripped. I then clean a blank gun even thought the process is very much the same.

I also talk a bit about cleaners and general air gun maintenance but for the most part I just show you how to clean the guns so watch the video!

I have found one of the more confusion aspects of guns is what defines the trigger action, and I confused this a lot at first but now feel I have a good understanding of what makes a gun Single Action Only, Double Action Only or Single and Double Action.

Your best bet is to watch my attached Vimeo video as it not only describes trigger actions but also has the added benefit of the visual examples of each type of trigger action.

Here is a very quick explanation of what constitutes each type of trigger action:

First off the action is based on the role of the trigger in how it effects the action, not how the slide or the hammer can effect the action of the gun.

A Single Action Only gun does one action (a single action) and that is generally the releasing of the hammer or striker or what have you... Single Action Only guns can not fire without first manually pre-cocking the external hammer or manually pulling the slide or charging handle back first to chamber a round and also pre-cock the action of the gun. Keep in mind that the blowback of the slide or bolt in semi and full auto guns effectively cocks the action of the gun allowing for single action trigger release.

A Double Action Only gun performs dual functions, the pre-cocking of the hammer or striker in the first stage and the releasing of the hammer or striker in the second stage, therefore performing two actions. Double Action Only guns do not have the ability to pre-cock the hammer or striker fully and therefore generally have a heavier trigger pull as the first stage of the trigger is to cock the sprung hammer or internal action.

Single and Double Action guns have the ability to do both, meaning they can be pre-cocked and then fired or fired without pre-cocking simply by pulling the trigger.

Keep in mind that there are some guns that fall in to their own category, take for example the Glock. Glock has been known to actually describer their guns as Double Action Only, when in fact they can not be fired without the slide first being pulled back to partially pre-cock the internal striker - similar to a single action gun. But when you pull the trigger on a Glock you do not simply release the action but rather the trigger first pulls the striker action back the final stage in order to release it, similar to a double action gun.

Again, watch my Vimeo video as I hope the visuals will help you to understand the differences between Single Action Only, Double Action Only and Single and Double Action trigger.

"Before you attempt to do this modification you need to be aware that it may void your warrantee and/or you may fail and either break something or incorrectly reassemble your Mini UZI rendering it "Broked"! This is your problem so please do not attempt this modification (even though it is fairly easy to do) unless you're 100% confident you can do it and are aware of the possible consequences. Make sure to also take into account any gun laws in your area prohibiting full-auto capable firearms!"

(Special thanks to Herman for showing me the ropes on this modification)

This modification will make your semi-auto "only" Cybergun/KWC Mini UZI BB Gun into a full auto capable 4.5mm BB machine gun. From the factory the full auto switch position (Far Left "A") is disabled but the full auto selector position is visible. The actual full-auto functionality is still present in the Mini UZI but has been decommissioned by the simple means of blocking the selector switch from being moved to the far left full-auto or "A" position.

This full auto modification will show you how to disassemble the Cybergun - KWC Mini UZI BB Gun and remove the small plastic selector switch blockage so you will be able to manually switch between semi auto and full auto modes. This modification takes about 15 minutes to complete.

You will need the following tools: A pair of pliers and either a pair of small wire cutters or a file.

Let's begin! Below are the two pre-modification positions available from the factory:

"S - SAFE"

"R - SEMI AUTO"

Below is a closeup of the top bolt cover that we will be removing to access the internal bolt for removal:

In the next photo we have removed the bolt cover by pressing the "angled button" towards the rear sight:

And now the bolt is removed:

I removed the grips but this is not necessary:

Now you will need to remove the lower receiver pin located at the back end of the receiver closest to the grip safety. Use a pair of pliers to pinch the metal pin while pushing it through. Once the pin is started you can use the pliers on the other side to pull the pin all the way out. You may need to us a fair amount of force to do this as the fit of the pin is tight:

Once the pin is removed the lower receiver can be detached:

You can see in the picture below the small plastic nub that we will need to remove in order to restore full-auto capability:

I used a pair of small wire cutters to clip this plastic nub off, but you could use a file too. Just make sure that the plastic is flush and does not have any burs or protrusions.

Below is a photo of the Plastic Nub removed from another angle:

After that, all you need to do is reassemble you Mini UZI in revers order to finnish the Full Auto modification.

In the below Photos you can see we have restored the ability to move the fire selector switch over to the "Far Left" or "A" position, reenabling the Cybergun - KWC Mini UZI BB Gun to shoot in full auto when desired.

"A - FULL AUTO"

Now enjoy your Cybergun - KWC Mini UZI BB Gun in full-auto as it was originally designed!

• SIG SAUER X-FIVE STAINLESS STEEL VERSION

DISCLAIMER, PLEASE READ AND UNDERSTAND!

• This walkthrough is for information purposes ONLY, if you decide to dismantle your BB gun you will void any warranty you have with the manufacturer.
•  I will not be held accountable for your actions or any damage that is caused by your negligence. Therefore, if YOU decide to dismantle your BB gun and break something during the dismantling or assembling it is your problem not mine.
• If you don’t feel confident or comfortable doing any of these steps STOP and do not proceed any further or you may do damage.
• YOU WILL LOOSE ALL THE SIG SAUER MARKINGS ON THE GUN.

Having said all that, this is my first ever instructional so I’m going to try and make this walkthrough as easy as I can for you to understand. You will need the following: Flat tip Screwdriver for the grips, Small Philips Head screwdriver, small punch & needle nose pliers – the last 2 are optional.

Make sure you have a clean work space and lay out every part in the order that you remove it Left to Right, come reassembly time you work Right to Left it makes reassembly so much easier.

Step 1:

Field Strip the slide until it looks like this:

Unscrew these 2 screws, these hold in the “Breech Block” once your unscrewed cup the end of the slide in your hand and let the Breech & Screws fall in your hand – Set these aside.

That’s it your Slide should look like this:

It is now ready for paint removal.

Step 2:

Take the Frame and start removing the grips Left hand side first:

Flip the frame over and remove the right hand side grips:

Carefully remove the trigger return spring, it is under tension and it WILL fly across the room – I spent an hour looking for it one day! Also while we are at it, you can remove the cover to the magazine release.

To remove the safety, place your flat tip screwdriver between the frame and the safety and twist ever so gently this will separate the safety and all you need to do now is grab the safety from either side and gently pull & wiggle until it separates.

Once the safety is removed you will see the safety bar, this lifts off.

Step 3:

Lift this little pin out and remove the spring, very carefully push this pin from the other side and remove, be careful because once this happens your hammer assembly is loose and free from the frame.

Slowly and gently remove the hammer assembly:

Note the little shiny piece that sits on the side of the hammer assembly, try very hard not to let this piece fly out, it is a pain to get back in, if it does fly out keep calm and take your time, don’t force the little spring in, it seats in behind the shiny metal thing – sorry I don’t have a proper name for it.

Also make sure that the spring next to it is in the locked open position, if it snaps back just get the tip of a small screwdriver and slide it to the left until it locks.

The hammer return spring assembly at the back of the grips can be removed and set aside.

Removing the trigger assembly is easier than it looks; you need to remove the takedown lever by rotating it counter clockwise until it stops.

Push it through the frame and rotate it back clockwise to remove it all together.

Remove the screw holding the trigger assembly:

Lift out the trigger assembly; be careful of the slide lock spring it wont Fly out, but it will fall out.

If you want to remove the magazine release, there is a spring that sits at the rear of the trigger guard;

Push the magazine release in part way & with the flat tip screwdriver lifts the up to remove it, once removed the magazine release will simply fall out.

THAT’S IT! We’re done, ready for the paint removal. Any paint stripper is fine.

KEEP IT WELL AWAY FROM THE PLASTIC PARTS!

Follow the manufacturer’s guidelines for use of their product and thoroughly clean the slide and frame after you have removed the paint.

YOU WILL LOOSE ALL THE SIG Sauer MARKINGS ON THE GUN.

Rub over the slide and frame with #0000 Steel wool or 1200 grit Wet & Dry paper. Clean again and using the paper or steel wool with some ALUMINUM polishing compound like Autosol and some good ol fashioned elbow grease polish the slide and frame until you reach your desired outcome. Clean it all down again and wipe it down with a rag that has had gun oil or my preference “Fluid Film”.

Reassemble the gun in the reverse order and viola one shiny SIG Sauer X-Five.
