I recently pulled the last tooth off of my Deep Fire Plolycarb piston.

Sorry for the crappy picture quality; I had to take it on my phone.
I ordered the KWA piston from the shop. And a M150 from AirsoftGI.com. Are there any recommendations of upgrades that I should get before I put this spring in? I know that the LE versions have that stock, but I just wanted to make sure.
Also, my stock motor is very easy to turn, and my brother-in-law's JG M16 motor is very tough to turn. I can spin mine very easily and was wondering if it was going out, or if that is just how the winding is?

FYI, LE trainers don't shoot full auto.   Plus they only have 30 round mags.  

On the other hand why is a Deep Fire piston in the KWA gun?  Did you brought it used?!

Haha, no I stripped out my stock piston by using a lipo that had a 30-335/60c discharge rate, and that was all that I had laying around. How long will the KWA piston last with the M150 and a 3 round burst function from my SW-EVOLUTION MOSFET?

Can't tell you.  Too many variables to consider.   You'll just have to try it out yourself.

That's what happens when you don't just use the KWA piston :P. The KWA pistons are reinforced on the back end. Also it should last a while with that setup but as Allizard said there are too many variables to give you an accurate estimate.

Ok, could it crack the front of the gearbox or something happen to the trigger post since the logo on the gun says KWA CORPORATION? That's the old one right?

Those are the older shell.  Trigger post aren't the new one.

So, since it's the old shell, could it crack the gearbox or could the trigger mech break with the M150 in semi only mode?

Why would a different piston crack the gearbox? The piston head is what would have a major influence on if the gearbox might crack, and the KWA cylinder head is plastic with a buffer pad so even a metal piston head wouldn't make a difference (as proven by the fact that KWAs come with a metal piston head).

No, I meant would the M150 crack it?

Let me ask you differently.  How long do you expect the shell to hold using m150 spring shooting on semi?

M150 is a little high but I don't think it will crack it very easily. I've run an M130 in my M4 (which is a Gen I which is less reinforced) for 50,000 rounds and I also ran an M150 in it for about 10,000 rounds. I'm yet to have a problem with anything.

Yes, that's exactly what I mean. Also, how long is the expected life of the piston, gears, and motor with the M150 in semi only?

With an M150 I wouldn't worry about your piston or gears ever having an issue. Also I think Allizard is asking for you to give him a number of rounds that you're looking to get out of it and he'll give you an idea of if it's realistic. I might be wrong but I'm pretty sure that's what he was asking for.

1st gen of our gearbox.  In a control environment, laboratory test, our gearbox have already pass 70,000 shots using m120 spring.   However, in real life application all the parts are subject to multiple variables condition.  Temperature remains the main factor.  Then you added the type of batteries (ROF).  Also bare in mind our piston have improved 3 times and the gears have changed 4 times since the 1st gen.  

There is not a straight answer for you.

Ok, mine is the first one of all of those, i[m guessing because it says KWA corporation. I live in Nevada so temperatures are pretty warm, and I have a new KWA piston on it's way. Is this the right M150? It's next to the stock KWA spring.

I am using a 11.1v lipo with a 30/35-60 discharge rate, but I have the SW-EVOLUTION mosfet from extreme-fire, so the battery shouldn't be a problem, at least I hope the mosfet will make it so the battery won't strip out the piston. Is 30,000 rounds through the KWA piston and stock gears a goal not to far out of the ballpark?

Wait a minute, the KWA KM-4s that say KWA corp. are gen 1? I got mine from ASGI about 9 months ago, and that is what it reads!

I'm just giving a general answer on what is in a Gen 1 gear box.  The shell inside not necessary have the gen 1 parts as production on the external body could overlap the rest of the production.  Either way, any KWA M4 body have the KWA cooperation marketing are at least 6-9 months old.

Alright.

Just curious, what version of KWA KM-4s are we on now?

I believe all M4's are current model.  I don't have specific name for which generation as our guns have a continuous improvement on every shipment. Ever since the 1st gearbox released, our gears changed 4 times and piston changed 3 times.   Small improvements that most people don't even notice and not significant enough to call a gen 2.

When 2009 model arrived than it will be call 2009 model (Duh) and will have more changes.  Can't tell you what it is... but we have this discussion before (Start digging up old post.)
