When you start a reply with this review is, "biased and unbalanced", you are injecting a personal opinion and therefore you made it personal but I'll step back a second and agree that I should have presented the review for what it was; A SINGLE DATAPOINT. In reality and to be mathematically correct, for a sampling to be statistically significant, you need no less than 16 datapoints. This applies to any type of statistical sampling from computing CEP's to determining failure rates. If you really want to get silly, the sampling can only be determined by changing one variable at a time, which gets really hard since there's a wide variation in the quality of airsoft parts from even the same vendor, so using your logic, and given the strictest requirements for determining a truly valid sampling, your review is as worthless as mine.
Let's get civil and reasonable. I provided some insight into my experience with a single King Arms gearbox, coupled with your Four successful tests, that is a 20% failure rate for King Arms boxes, which by any standard is too high to consider them a good investment at this point.

im sane enough to realize that the version 2 gearbox design is FLAWED so i dont go thinking ill get a ridiculous amount of rounds out of a high fps version 2 box.
You basically demanded ferrari performance out of a kia.
Now, I have gotten a few comments referring to our idiocity of putting a 170 in a V2. However, we have been running a Classic Army stock V2 box with a 160 chroning at 500FPS for at least 15,000 rounds with no cracks. A "reinforced" gearbox should not crack with less than 500 rounds through it, despite spring strength. Most people will stick a 120 in their boxes, and eventually even they will crack, but this is simply a foreshadowing of that outcome.I am running a stock CA V3 gearbox for only 500 rounds, but happy to report, no cracks.
I will not buy another King Arms box, simply because the Systema is just as good (better in our trials) for the price.

As I predicted you took it personally and not for the objective criticism I was trying to provide.
Seriously?
Your review is biased and unbalanced.utter nonsense.my low opinion of your biased reviewThat sounds like objective criticism to me! (Sarcasm in case you missed it)
First off, what are you talking about? You took specfic examples from my generic meaning (boots, optics, etc) and began to critique and analyze as if you were going to finish with an over solution that will prove my post wrong. Missed it completely my over zealous airsofter, YOU said only reviews with 3 example would be credible, no specifics... My response, any one who reviews anything is an idiot under your paradigm, why? Everyone who ever writes a review is biased if they haven't had 3 of them.
Second, do YOU even know what your posting? A Full guarder cylinder set in every box, and yet a "TM piston - TM piston head" in every box. Not sure how your fitting two pistons, and two piston heads in everybox (since every Guarder cylinder set I have ever seen has come with a piston, and a piston head). But hey, it must be possible since you have done 5 gearboxes! Man, thats more than anyone ... EVER!
Also, all of your examples included springs less than 170s. You apperently have ZERO experience with 170s in King Arms 8mm boxes. Why are you even posting? Seems to me you are lacking the experience required to be posting in this thread.
How can you even say they are proned to bad casting when I just gave you 4 examples of GREAT casting?It's entirely possible you just got one bad casting/moldingOh and by the way, I gave you one example of "bad casting" because mine broke! In case you missed that also.
-
The 3 different problems we had with them, (Cracking, anti reversal latch, gear grinding) is a clear statement that it is not just, "bad casting".
And according to your friend, your only allowed to review something if you have had 3 of them. I guess every review in this section would be described as, "biased and unbalanced" and "utter nonsense".
-
In that light, they are obviously proned to "bad casting/molding". Therefore I still will not buy another, nore advise anyone else to either.
Seems to me your post lacks credibility. Where are your parts lists? Pictures? Anything to even slightly show that your not just rambling.
And I guess anyone who has a review about a gun, a optic, a pair of boots, a bag of bbs, or any thing else on this forum is also considered "utter nonsense"... Right? So you can only say something is "poor", only if you have three of them? What if I rated the king arms box great, would you have sh*t all over me for not reviewing three of them? I didn't think so.

King Arms 8mm V2 Gearbox
*note, bear with me on these pictures. Photoshop is currently down on my PC, so had to use other editing programs.
This gearbox is listed around $40 to 60 dollars depending on where you go. It has 8mm bearings which is nice, suggesting that it is stronger than 7mm. Comes with what seemed to be a high end switch and tappet plate.
It has reinforced sections around the gears as shown.
We tested this gearbox on Aug 14th. A list of parts is mandatory to explain the outcome.
Guarder Silent piston head
Guarder Cylinder
Guarder Cylinder head
Deep Fire Titanium teeth piston
Systema Super torque Helical gears
Systema Magnum motor
Systema m170
The platform was a CA M15a4, with stock hop up unit and mad bull bucking.
After carefully shimming the helicals and test firing, it was off to the range. The distance was very nice, shooting well over 240ft with .30s and the CA stock 509mm barrel. With a 2400Mah battery and a Systema Magnum the ROF was about 15 rounds a second. After coming in from shooting we decided to take a look at the wear. There was little to no wear on any of the parts, however we had to grind down a section of gearbox due to grinding issues with the helicals (See 1A). We than attempted to rear wire it, which in my opinion is harder than other gearboxes. As noticed in this picture (See 1B), there is a random hole in the back of the box which makes the wires sit rather loose, and then are proned to "pitching" when closing the box.
We also had problems with our anti-reversal latch. We tryed a systema, guarder, and a "XYT" brand, all grinded with the spur gear. We eventually grinded down one of the anti-reversal latches. After installing it back into the body we noticed something rather shocking.
We checked the other side and...

Over all this box looks nice, the performance was good, however the durability is below poor. I would not recommend this box ever, unless you are using a M90 spring.
The next gearbox we are going to review is the Systema V2. The walls near the cyilnder are almost twice as thick as the King Arms box, and we are predicting that it will last alot longer.

Update
I fitting the following parts into the gun...
Wired with deans of coarse...
Guarder Infinite Torque up motor
CA Super Torque Gears
SP170
Pro Win Hop-Up
Gone through about 2000 rounds with a 150, and about 200 with a 170.
It was chronoing 490 (with .20s) with the 150. Haven't got the 170 chronoed yet.
Its shooting very hard. Range is around 250ft. Wondering if a tightbore will help with a tad more range. Dee's customs are no where to be found so a tight bore doesn't seem practical now.
New picture update...

Someone made this for me on another forum. It was kick a$$.
-
Thanks guys. I recently fit a SP120 in it and it is shooting great for now.
I would argue that my max range is about 150 feet, accuratly. Thats everything stock with just a 120 spring, so not bad.
I will repost my results after fitting it with super torque ups, and a sp150.
-
Nice, where did you get those top rails from? I know they come on the Star version but I have had some trouble finding one... Nice instruction manual on how to mod the scope....
-
Thanks for moving it, I thought techinical would be the right area. I was wrong.
-
Well I am glad everyone thought this review was helpful. Remind me not to post a review on here again...

I have recently aquired a SL8 as well...

I just recieved this gun yesterday from Airsoft Tactical. (Chattanooga, TN)
It was $300, and came with two low caps, umjamming rod, and a scope.
This gun is basically a G36 with a different body and a stock 6.04 tightbore. The gearbox, hop up, all the same, it also takes the same mags.
My first impression was how durable it felt despite it being plastic. The bipod on the front is surprisingly sturdy for being plastic.
Out of the box capabilities I would rate it very poor. It was unaccurate, underpowered, and the scope was hard to sight in. It also takes mini style batterys, and one who is used to a 4500 MAH battery in a crane stock, this is just frustrating. It took me about 10 minutes to figure out how to close the foregrip with the battery in. My G36C quietly takes 9.6 minis, this one however did not. My first instinct (if you can call it that) was to wire it to the back in that oversized stock, but I gave up on that idea when I looked and needed a power saw to make enough room for a battery to fit.
However, there are few things I would note. The scope that it comes with is nice, good to look through. However I don't see myself keeping it on there very long.
The cocking handle which reveals the hop unit is metal, unlike the other G36 series. It seems that they stuck with the same spring to propel it back, because it is a little slow.
That trademarks aren't bad either...
On to the internals...
To get into the gun it was suprisingly simple, more simple than a G36 and me being mostly an armalite user, I was plesently suprised.
The first thing I did was swapped out the CA bucking for a Systema, the hop up units on the G36 I never really liked. The barrel is always lose, so I am sure I will be looking for an after market hop up farely soon.
The motor is a standard classic army "high torque" motor. I don't see myself keeping that very long. One note which I find frustrating is how Classic army refuses to put motor tabs on thier G36s.
Inside the box I was pleased with the quality. The compression was very nice, I didn't have to lube or adjust anything. As you can see in the picture, it comes with an aluminum piston head, aluminum cylinder, bearing spring guide and a bore up nozzle. The gearbox comes with 7mm bearings also. All of that makes this gun very easy to upgrade out of the box.
I decided to switch out the stock spring (which was putting out around roughly 300FPs) with a Guarder m120. As I pulled out the spring guide I took a closer look at and noticed it was cracked, Sh*t the bed. Luckily I have more spare ver3 parts that you can shake a stick at.
*note* Timing on Ver3 gearboxes are notoriously difficult. The trigger (which is always lose untill you close the box) is constantly spinning the gear as the spring is propelling the piston and cylinder upwards. Pain in the *albatross* but worth it...
Overall I am farely happy with it. Due to lack of funds it is not up to par with my other guns. But after a Dee's tightbore, a SP160, Super Torque up gears, a Guarder infinite torque up Motor, than I will be a happy camper.
