Upgrading a GBB - Which parts do what exactly

[j4ypal]

Hello,

First of all, yes, I am new to airsoft, I have been looking into it for a few weeks now. I have attended a local meeting last sunday and I will definitely get into it soon. I can already feel the addiction rising inside of me. I know this is a thread about upgrading. So let me do a preemptive strike here. I know you'll say: "hey get your gun, play around with it, and then worry about upgrading". There's one thing I know about myself. I am never satisfied with what I buy retail. I am always hacking, upgrading and modifying my stuff. This won't be any different. I won't have a stock gun in my hands for very long.

Being that for now, I cannot allow myself to spend 1000$+ on gear, I will not start hardcore airsofting this summer. BUT I still want to have fun and experience something related to airsoft. So instead of going for an AEG and all the gear, I'll buy a GBB and just go target practice. I'm sure I'll have a hell of a lot of fun and it'll be cheaper (for now).

On to the main topic.

I am 99,7% sure I'll pick a KWA Glock 19 from 007. From what I have read, there are quite a few parts you can buy to improve performance on a GBB pistol. Here is what I have gathered up to now, including the blanks I have yet to fill.

1. High Flow Valve (Approximately 20$ from Uncompany) - Increases the amount of gas pumped for each shot, thus increasing muzzle velocity.

2. Stronger Recoil Spring guide (Approximately 5$ from uncompany) - Stronger rod allows the gun to take the stronger shock of upgraded internals.

3. Recoil spring? - I have yet to understand this one. Is this helpful in any way for performance? Does the spring come with the Recoil spring guide (number 2). In almost all the stores I've looked at, they show a picture of a rod and a spring but only mention "Spring guide" in the description.

4. Stronger Hammer spring (Approximately 5$ from uncompany) - Highly recommended since it helps open the valve to let the gas in.

5. Rocket valve/Floating valve (Approximately 10$ from uncompany) - Ok. I have yet to understand this one too. I have seen whole bunch of these everywhere. I have also seen problems with installing these. Are they helpful for performance? What do they do exactly?

6. Tighter inner barrel (Approximately 25$ from uncompany) -
a) Helps increase accuracy by reducing the movement of the BB inside the barrel.
b) Increases muzzle velocity by allowing less gas to go past the bullet inside the barrel. Since there is less space (almost none) for it to go past, it will push the bullet out more rapidly.


Any and all comments appreciated as long as they are constructive.

Best off with just Tighter Barrel, Hammer and recoil spring, and new metal slide.

And if you can afford it a KSC Glock 19 is alot better quality.

From what I have read, a lot of people have bought KWA Glocks and are very satisfied with their purchase. I remember seeing a post from a guy who said he hosted airsoft games. He had people shooting his KWA glock 19's everyday for like 2 years and the guns were holding up just fine. They seem like workhorses to me.

The only difference between the 2 factories are quality control. If I end up with a lemon, I'm sure 007 will be glad to send me another one (this probably happens 1/1000 of the time). Also, the KWA comes with a metal slide pre-installed which is why I'm picking the KWA.

Bottom line: For 250$ CND, I have a Glock 19 with a metal slide, just can't beat the deal.

The difference is not just limited to QC. There is a material difference between the lower receivers. The KSC G19s have a heavyweight metal embedded polymer frame, giving the gun a MUCH more solid feel over the KWA counterpart. Add a metal slide to that and you'll understand why KSC users love their G19s over KWA. The cold feel you get each time you grip the gun, plus the weight gives the gun a much more solid experience.

Go with a KSC...

My current, KSC Glock 19 is a tank.
It was broken, wouldnt fire at all so I took it apart. What a mess. But now it works with the following things broken:

Part # 88 is completely broken. The piston is actually snapped off and just sitting inside of the nozzle.
There is no piston return springs.
And the trigger return spring is made out of a cut and bent up pen spring.

And it fires no problem.

As a proud new KSC G19 owner, I agree with the rest, go with KSC. Quality, feel, performance, just cant be disapointed.

I feel a little weird here since you're kind of the master here. But why does this guy say the KWA has a Heavy Weight frame too? : http://aasurplus.ca/airsoft/product_...products_id=73

Is he ripping people off?

I'm not sure. He's either misinformed/confused, or that product really is a heavyweight.

Which goes to show another issue with KWA products: they don't have a consistency in their product line and are prone to changing up the product. If you search for reviews on KSC Glocks, you'll get several different reviews with what appears to be different guns all the time.

My experience: I haven't come across any heavyweight G19s from anyone but KSC. But then again, I stopped paying attention to Glocks about a year ago, so it's possible that KWA has changed their product again... although I can't confirm that.









You shouldn't need a stronger recoil spring guide rod. The stock one should already be metal. (I'm not positive about this for KWA. I know it's metal on the KSC)

You need a stronger recoil spring. The stock one is too soft for the KWA metal slide... or any metal slide for that matter. It speeds up the blowback speed. A soft spring with a heavy slide will result in sluggish performance. The enhanced spring will return the spring much faster for higher ROF.

Rocket/floating valves have wider openings to allow more gas to flow through. This results in higher velocity, while increasing durability over the stock plastic one which is prone to breakage.

Yes, his is in fact the "HeavyWeight model" it comes equipped with an Enchanced Recoil spring, and Metal slide/Barrel. However it has no Trademarks and the evidence of a previous Orange tip... but this gun truely is a workhorse and the perfect sidearm (Having gotten mine yesterday, i can 100% say it beats my KWA 18C-stock.)

Ok. Thanks for the info.

Also, thanks Illusion for your tips.

I guess we can be almost sure that the AA surplus KWA glock 19's are Heavy Weight.

I have a question though. Does anyone know if the 007 KWA glock 19's are Heavy Weight? Anyone own one of these bought recently?

007 hasnt had anything In-Stock for the longest time ...unless Ken is going to Import one in specially for you? If not I suggest you Pounce on Marks G19's its a great price with 4(?) still in stock, Due to the price of them of course

Thanks for all your info. I'm getting more and more convinced I want a KWA.

One more little thing. What do you mean exactly, when you say there is evidence of a previous orange tip?

Meaning it came from the states, lesser quality gun with orange tip to fool customs into thinking its a simple toy, ect. Most are just spray painted over and thats what he meant

I bought my KWA G19 from A&A and I posted a nice lengthy review for new users like yourself. However I forgot to mention I noticed something strange about my slide. I believe Mark gets some of his guns from the US and he or the company he buys from repaints them. A hint of red is noticable inside the slide and you might find small dried up red paint on the front sight. Just use a toothpick or something with a small point like a needle to pick out the residue. My glock looks absolutely fine. It isn't a problem at all unless you care about the red inside the slide. I'll take a picture of it when I have time. Some other members here own G19's and I'm sure they can tell you all you needed to know

A lot of you guys seem to have a thing against KWA guns but I have yet to see a meaningful review of a KWA glock saying what's really wrong with it.

And I don't want to start a flame war here. It's just an observation. I'm trying to make the best decision I can.
