In anticipation of the 2009 new product premier at the 2009 IWA show.  We've initiated this thread to discuss the progression of the KWA KM4 series.  New information about the 2009 models will be revealed every week up till March 13th.  Please feel free to join in the discussion.

PS - There's no need to stop buying or sell your existing guns.  Most of the M4 series at "KWA Authorized Dealers" already have the updated internals and 80% of the new improvements can be retrofitted to your existing guns.

Alright folks, I am going to talk about our progression on the sector gear.

But first, let me show you these two pictures.  For those of you that have worked on Toyko Marui, this is the stock aluminum sector gear.  

Posted Image

Posted Image

Let us move on.   We introduced the M4A1 back in Augest 2007, I believe the very first version released did not have a sector clip.  The pictures showed below already have a sector clip installed.  Notice our gear have a lot more material compared to TM gears.

Posted Image

Posted Image

Shortly after releasing the CQB, we noticed some of our gears are striping.  This is also happening on spur gear and bevel gear as well.  So we have decided to change the hardness of the gear by cooking them.  Also known as Heat Treated Process.

Posted Image

Posted Image

Above photos showed the HALF cooked sector gear.  It was used on majority of the products from mid 2008.  Then, we asked why only cook it half way.  So we have decided to cook the entire gear.  See below.

Posted Image

Posted Image

This is the most current sector gear in all of our production.  

Now I am going to throw you a curve ball.  Anyone know what brand is this sector gear below?  

Posted Image

Posted Image

Anyone?!

If you guessed it's a Systema Torque up gear then you are correct.   It does look exactly like our sector gear isn't it?!

Maybe not.

Posted Image

KWA on the left, Systema on the right.  Something is a little different here.

Systema gear thickness is 4.08mm

Posted Image

KWA is 5.00mm

Posted Image

Yes... our gear is a LOT more beefy!!

Want more info on 09?  You guys will just have to stay tune on this thread.

Someone ask me if I will be giving away too much information on our design.  I can tell you this, there is a lot more engineering involve besides cooking the gears and making it fatter.  So nope... I'm not worry and I welcome the challenges.  That's what drives us to make better products.


Continue where we left off.  

Besides the sector gear, spur gear and bevel gear is now also heat treated.  And now even the Anti-reversal latch is heat treated.  

Posted Image

If you look closely, the untreated one on the right already have some wear mark.

Anyway, moving on to the Cylinder and Piston.

Posted Image
From right to left, 1st gen, 2nd gen, 3rd gen.
  
Posted Image
Comparing 1st gen and 3rd gen.  Not only the metal plate is heat treated, the 1st tooth on the piston area is also reinforced.  And the tooth is a few mm lower to help engaging the sector gear (AOE)  Material is also change.  And it's something you can't see from naked eye.

Today I'm going to show few more minor improvement on the body.  This is what it's going to be on the 2009 model.

Posted Image
Metal nut insert is now on the new 2009 grip.  

Posted Image
Bottom - Original motor plate.
Middle - Current production, this is implemented since the release of M4 CQB.
Top - 2009 model.

And... I will quote the following from Radix

Folks, You really don't need to buy anything until they need replacing.  The comparisons are to show progress and evolution of our products. We're really NOT trying to entice you to buy new parts.   Please hold on to your wallets. :)

Cylinders

Posted Image
Top - 2nd Gen Cylinder on M4A1 and M16, moved backward and increase a little more air flow.
Middle - 1st Gen Cylinder on M4A1 and M16 (Type 1)
Bottom - Cylinder on M4 CQB, there is no change.  Notice the port on BOTH side.

Moving on to another improvement.   In the past, we have some people complain our LE stock seems to rattle a little.  The cheap fix is put electrical tape on the buffer tube.  By the way, if you ever own a real AR.  It happens on them as well.  Anyway, we have come up with our own fix.

Posted Image
Old LE stock

Posted Image
New LE stock - Added rails on both side which act as a spacer so when you extend the stock it will not rattle anymore.  This is on the current model since fall of 2008.  Most of you already have them.

I'm glad I took these pictures couple weeks ago.  We are extremely busy preparing for the IWA show.

For those of you who have worked on our hop-up unit probably have seen this.
Posted Image
I call them the "Hop-up C-clip"  One on the left the original type.  On the right is the new type which is also on the current release.  If you haven't figure it out why then look at the next picture.

Posted Image
Our stock brass barrel.   Bottom is the old type and top is the new type.  Notice the groove is longer on top?  This is where the new clip comes in handy.  When it clamps on the barrel it will STOP the barrel from twisting.  Imagine if you don't have the longer groove during installation, your barrel can twist a little left or right.  That can also make the bucking "off center"  hence your BB's don't fly straight.  Locking the barrel down will minimize the problem.  

And one more thing, if you replace the stock barrel with a new Tight bore barrel, it might not have the longer groove.  And when you put the clip on the hop-up this will happen.
Posted Image
not only this make the hopup unit very hard in put back in the outer barrel but also create air leaks.  Not a good idea.  A simple fix is to file down inside of the clip.  Then again, there are some TBB does have a longer groove as well.  Like EDGI, Guarder etc....

Alright, too much information where did you get shot.  
-_-


I'm going to side track a little on our cylinder head.

Can someone compare the sorbo pad thickness for me?

Back on the topic.

Here is one major improvement on the 2009 model.

Posted Image

Posted Image
The older barrel is one of my pet peeves.  I'm so glad we are now using a true one piece outer barrel on 2009 models.  And for the record these barrels will fit our current receiver and will be available to purchase later this year.

I am hoping to see a larger handguard, ris rails, or crane stocks incorporated because that is one of the problems i have with my current gun. Any idea when we will be able to get our hands on a 2009 model even though it has even really been announced yet?

I don't know if it's necessary talk about this.  Since most of you already know...  :rolleyes:

Posted Image
Old on the left, newest on the right.

Posted Image
Between original and the current release.  Last spring we noticed our guns were not shooting properly when it was too cold and the BB's were rolling out of the barrel.   2nd revision on the right changed the material and it worked much better than before.

Posted Image
On the right is the latest design and can be found on some of our guns and will be on every 2009 models.

This week we will explore the exterior changes.  First, the KWA logo has been redesigned, if you haven't already noticed. :) Second, there will be individualized serial number on all guns. Third, we've changed the finish to a matte dark grey instead of black.

Sweet!  I just noticed the logo change on the top of the forums too, haha.

Now when will we find out what "KWA" stands for?

Edit:  Is the rear pin missing a screw?

Another improvement would be putting a hex on the other side of the rear pin to make it easier to take out, I hate it when it spins freely and I have to hold it down tight with pliers and a cloth.

Making the selector markings visible would be awesome too.  And also to make the caliber "5.56 mm" instead of "6 mm".  I always thought that it was cheesy for it to say "6 mm".

Just some of my suggestions.

Just some of my suggestions.

^I looked at my rear pin and on the other side it is just a circular hole.  I'll check again when I get home.

Having it say "5.56 mm" just makes it closer to a replica to me, the same way the barrel says "5.56 NATO", ".45 Auto" on my USP, and "5.56 mm" on some silencers (all aforementioned for airsoft use of course).

I'll still be buying one when it comes out though, lol!  These are just minor things that would make it perfect to me.

Then you have a older body pin.  

We are selling to Law Enforcement as a training weapon.  It wouldn't make sense to put 5.56mm on it.

But you brought up a good point on the marking on the barrel.  Needs to be consistence.

Correct markings are required by LE & Military. Imagine a Law Enforcement Officer mistakenly takes one of these guns out on a 10-32 call. :o

If it were me I still perfer the old KWA logo, but I do however like the Cal. 6mm and serial numbers.
The old KWA logo had a good design sense to it, the lines on it made it look like it had movement when standing still, it flowed nicely. The new one looks more rigid and modern, just my take.

Meh, a little thing like a logo still wouldnt hold me back from purchasing one if I didn't already have a KWA :)
