"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.

• UMAREX SA177 CO2 BB AIRGUN - FIELD TEST

• UMAREX HPP CO2 BB AIRGUN - FIELD TEST

I received both of these Umarex blowback BB guns (Umarex H.P.P and the Umarex SA177) about a month ago and so far I have very little to complain about either of them!

Some of the specs:

• Both of them are CO2 powered

• Both of them shoot 4.5mm BB's

• Both of them have blowback action

• Both of them shoot around 400 FPS

• The H.P.P  is styled after the Sig Sauer 266

• The H.P.P is mostly all metal construction

• The H.P.P has a 15 round magazine

• The SA177 is styled after the Glock

• The SA177 has a metal slide and composite frame

• The SA177 has a 19 round magazine

• The SA177 has fiber optic sights

Here is a quick summary of these airguns…

Both of these Umarex airguns are great value for the money and both shoot pretty hard and accurate for blowback styled BB guns. Both have long trigger pulls with the SA177 being a bit on the heavy side. Neither one has a very heavy blowback feel but there is enough blowback to make them responsive and fun to shoot.

The construction on both of these BB airguns is overall very good with the SA177 being more realistic in comparison to the H.P.P. The H.P.P tends to be a more comfortable gun to shoot because of its weighty feel in the hand and lighter trigger pull.

I highly recommend both of these air guns. If you're looking for realism then get the SA177, and if you want the better shooter of the two, get the H.P.P.

I will be doing a more thorough shooting review with videos for each one of these Umarex blowback CO2 BB guns in the near future so stay tuned!

Here is the Vimeo Video of my Umarex H.P.P and SA177 Comparison/Review:

Pros:

• Extremely realistic airgun replica of the original Sig Sauer X-Five P226.

• All metal construction.

• Blowback action is very firm adding to the realism of shooting this weapon.

Cons:

• It goes through CO2 very fast.

• When the magazine releases, it simply drops out, no spring to it.

• No adjustable sights.

Comments:

This BB air pistol is styled after many modern blowback airsoft pistols, this means it functions very similarly to the real steel. It is a very hefty gun made almost entirely from metal and has a very snappy blowback action which adds to its shooting realism. Even the magazine looks and feels like a real 9mm magazine with similar weight and dimensions. The Cybergun Sig Sauer X-Five shoots very accurately for a BB airgun and has fairly decent power considering it's blowback function, this does result in heavy usage of CO2. I was able to get about 3 magazines out of a CO2 cartridge. This is one of my favorite airguns because it is so true to form and function.:
