Review: The Systema Revolution

This one has been a long time coming.

Background:
Last year I decided it was time for a gun upgrade. I had no idea what I wanted, but I was ready to spend a decent sum of money for something new. The decision finally came down to choosing between the Systema Revolution Gear Box, or a Systema PTW challenge kit. Now from here on out, I know a lot of people would say “Well that’s obvious, buy the PTW”, and we’ll get to that here in a few moments. I was willing to spend in the $500 dollar price range, which is just about perfect for buying the Revolution. In order to buy a PTW Challenge kit, I realized I would have to sell my CA M15 and other gear. I was perfectly fine with this, I mean if you’re going to end up spending an additional $500 dollars, who wouldn’t trade a CA M15 for a PTW.

The main reason why I was even considering the Revolution was because it essentially functions like a PTW. Now I realize that the Revolution is NOT a PTW by any stretch of the imagination, but in terms of how the gun responds and the basic technology involved, they are quite similar. Two of the biggest functions that the PTW has over the Revolution are:

1) The ability to quickly change cylinders, and therefore FPS
2) The planetary gearbox design

My line of reasoning was as follows: “If most events require under 400 FPS, there is really no huge need to have the ability to quickly change FPS”. And that is mostly true. Majority of the events in Ohio have a maximum AEG FPS of 400. While there are some exceptions (Such as the Mansfield Reformatory), I was not too discouraged being able to attend most events in Ohio. Secondly, the planetary gearbox is not too big of a deal to me. I was looking for how the gun outwardly performed, not how it reached the means to that performance. While the planetary gears are very unique and feature a sturdy design, to me it was not worth spending the extra money.

**A quick note on my financial position at the time:
As I stated before, I was willing to spend about $500 dollars on a new gun/upgrade. A PTW challenge kit costs $1100 dollars, including assembly. Not a problem, because I could have sold my current gun and some gear and made up for most of the price difference. But on top of that, I would have to buy magazines, batteries, and possibly cylinders if I wanted to take advantage of the gun’s FPS changing ability. That adds up to a good chunk of money. Of course, I looked at this in the long run as well, meaning I realize I did not have to buy all of that at once, but it’s still a rather large investment. Some might say “Why not spend just $300 extra dollars on top of the $1100 to build the gun?” I answer because that’s $300 less dollars I have to spend on college and books, which is above all my first priority.

So:
I decided upon the Systema Revolution M110 for the M16 with rear wiring. I planned to drop the gearbox into my CA M15 CQB, and I was happy with that plan.

Research:
I was slightly concerned because the Revolution was still pretty new on the market, and solid reviews on it were hard to find. I did find some, and from what I read the gearbox seemed to perform above and beyond expectations. I did read several things, however:

1) The gearbox was designed as a direct Tokyo Marui drop in GB. This meant that it might not fit perfectly in other similar GB designs, such as CA, G&P, etc. Since there were not a lot of reviews, it was difficult to say what the Revolution would fit in and what it wouldn’t. A possible problem.
2) I would need to buy a Systema Hop-Up unit in order to avoid jams and ensure a perfect seal between the hop-up unit and the gearbox. Not a problem.
3) I would need high quality magazines. The suggestion I was getting from everyone (Including Wallace @ Systema) was to use Magpul Pmags. A slightly bigger problem.
4) I am a sucker for Crane stocks. Period. I was informed by Wallace that the Revolution wiring (because of the fuse if I recall) would not work with a crane stock because the wiring could not pass through the small space needed to enter the buffer tube.

The hop up unit and magazines were not huge problems, although I knew Magpul Pmags were expense, they are still less so than PTW magazines. The biggest problem was the lower receiver, which might not fit the Revolution correctly (That would be a huge problem if my new revolutionary gearbox did not even fit inside my gun right?). I figured that CA was a reliable brand, and that out of all the possible receivers, I gave a CA one the highest chance to succeed. The crane stock issue was an annoyance, and I finally convince myself if I couldn’t find a way to make it work, then I would submit to a full stock.

**NOTE: The Revolution is VERY picky about magazines and hop-up units. It is STRONGLY recommended that a Systema Hop-up unit is installed, and the gun is used with high quality magazines. The Revolution feeds very fast, and needs strong magazine spring tension to keep the bb’s feeding properly. These warnings come straight from Systema. I would advise that if you do not want to risk ruining you brand spanking new $500 dollar investment, follow those guidelines.

The Process:
I ordered the Gearbox through a local Ohio retailer who I trusted, and waited. Long story short: the whole installation process took a very long time. It ended up that the retailer was having trouble fitting the gearbox and getting a poor FPS reading, most likely they said because the GB nozzle was not seated properly with the Systema Hop-Up unit. They ended up sending the whole deal to Wallace, who ended up having to mill a portion of the lower receiver to fit the GB properly. I expected and was ready for possible complications with the Revolution, but it took about 6 months for the whole ordeal (From the initial special order which had to ship in, to me receiving the gun).

I am in no way displeased with the retailer I ordered the GB from. They had never dealt with a Revolution before, so how would they know a portion of the receiver had to be milled? It was difficult at time communicating with them, but overall they did as best they could and handled the situation very well. Thanks to Wallace as well for working on the lower receiver.

Finally: The Gun
A quick note on the Crane Stock: Upon receiving my gun I realized for myself that the wiring would just not fit through the crane stock as it normally should. But as I said, I am a sucker for crane stocks, and I was going to try. I ended up having to file down 2 portions of my buffer tube to thread the wiring through into the tube. Although it is not normally how it works, you can hardly see the wiring and it still looks good. I am still consistently checking to sure the mod does not pinch or wear at the wires, but so far so good. (Pictures later) I knew there would not be enough room in the crane stock for a center battery piece, so I ended up buying a PTW custom battery, which fills only the two outer tubes. The wiring is a little short, but it works until I can buy a better battery. The stock still cannot be adjusted to its smallest setting, as it is holding the fuse, the two large connectors, and a ton of extra wiring. I plan on switching over to deans connectors later and possibly removing the fuse (which will not void the warranty).

The Box:
In the box I found my gun safely wrapped, and the Revolution GB Box, with my old GB and motor safely tucked away. The box itself has Styrofoam fitted to the shape of the gearbox and motor, and room under that space for the wiring.

Shooting the Gun:
I loaded up a MAG brand mid-cap, which was the only M4 magazine that I had at the time. I connected the battery and took the first shots. The first thing I noticed was the crispness and ease of the trigger pull, almost nothing. It feels exactly like a Systema PTW in a side-by-side comparison, I would venture to say the same. The response of the gearbox is also incredible, and like the trigger pull reacts exactly like a PTW. The gun shoots on semi-automatic as fast as you can pull the trigger, with each shot matching almost exactly with each pull of the trigger, with less than a second of delay. The gearbox also makes a distinct ring compared to my previous regular V2 gearbox. I did not try fully-automatic yet, as I was using MAG Brand magazines and did not want to further the risk of a jam or worse. They worked fine when using semi-automatic, but again I used those magazines at my own risk and is NOT recommended. I am looking to place an order of Magpul Mags soon. I am not sure of the FPS, but I am confident it is between the 350 – 370 FPS range, as the gearbox is rated for around 360 FPS. Overall, the trigger response was amazing in comparison to a PTW, and far exceeded the feel and response of a normal AEG.

**NOTE: Do not buy this gun if you expect to “lay on the trigger”. The main purpose of this gun is found in semi-automatic firing mode. While I’m confident that it will perform fine on fully automatic with a very high rate of fire, that’s not what this gun was designed for. It is basically built to be a semi-automatic platform, and it performs over the bar in that regard. The main reason for being careful when using automatic is the fact that every time the cylinder compresses/decompresses the O-Ring needs time to reshape. Therefore, it is advised that trigger pulls of over a minute should be avoided (Not that anyone should do that anyway).

Opening the Gearbox:
(Soon to be written, after class)


Conclusion:
In conclusion, this gearbox really is amazing. The downsides are that it is very specific in the type of magazines and hop-up systems it uses, and that in most brands excluding Tokyo Marui, lower receivers must be milled in order to house the gearbox. The trigger pull and response very closely mimics that of a PTW, so in essence, it performs like a PTW in that way. The gearbox is made out of high quality materials, and is very easy to open and work on. The gun performs brilliantly on semi-automatic, and shoots like a dream.

That said kids, just get a PTW. For the amount of money I will end up spending on magazines, the gearbox itself, and special batteries to fit in the crane stock, I will end up spending a little over $700 dollars. If you are looking to make a big upgrade, just save your money for a little while longer and buy a more stable platform. While the Revolution is amazing, I do wish that I would have just saved during those 6 months and bought a challenge kit. The overall system that you buy when you get a PTW just makes it worth it. Right now I feel like I have a cross between a Systema PTW, a Classic Army, and a meh. I guess that’s what I expected, but in the end a PTW just feels like a more solid platform and has many improvements over what the Revolution has.

Pros:
- It is still cheaper than a PTW overall
- Mimics a PTW in trigger pull and rate of fire
- Very crisp trigger response
- Easy to open gearbox
- Sturdy internals and electronics

Cons:
- Milling of lower receiver most likely required
- Recommended use of Systema Hop-Up
- Recommended use of Magpul Pmags
- Tight fit in crane stocks
- Cost

I will be adding to this review later today, including more specific gearbox specs.

I also have a Revolution. Bought it in 09 in spite of all the naysayers and warnings I've read over fitment online. Had mine installed by DA at zShot, and love it. Shoots 389fps on the button. I also have a 2009 PTW Max and can vouch for the trigger pull being nearly identical. It also definitely sounds better than my PTW Max, and any other PTW I've heard (both before the 490 motor and with it).

Something to remember when fitting these that DA pointed out: if you over tighten the rear stock bolt you can actually tilt the front of the gearbox up out of the lower slightly, lifting and changing the front angle where the nozzle meets the hopup chamber. Lowered fps ata min, ruined gearbox at a max. Be sure not to over tighten it. OR, do as I did and install some shims in the back so the gearbox isnt pulled backward as you tighten the bolt.

CA is about the worst body choice to make one of these fit. I've heard G&P do ok.

Here is the body I bought, and it turned out to be a drop-in perfect fit right out of the box:
http://www.ebairsoft.com/dboys-metal...16-p-1890.html
Yes, I used a DBoys body kit for my $500 gearbox. And do you know what? I love it. Its gone thru several events last year, and even one game loaned out to a completely new player and survived without a hiccup.

I use these mags with it:
http://www.airsoftsmith.com/store/pr...oducts_id=1574
and have had zero feeding issues, both in semi or full auto.

I did not use a crane stock but used this in an SPR build-up, so went with the Knight's type Sniper Stock (full)

Here is the final result.

Why buy this? For me, it wasnt about price: I can afford a PTW and in fact already have one. The Revolution allowed me to put the PTW performance into a body of my choosing and use mags of my choosing. Also, I was this -><- close to getting it to fit in a VFC SCAR L body (If not for interferance with the selector circuit of the Rev and the SCAR's ambi fire-selector axle).

I wholeheartedly recommend the gearbox.

Receiver fitment is key when installing the Revolution Gearbox. The Revolution, as well as ANY SYSTEMA replacement or upgrade component is designed to fit Tokyo Marui (TM) platforms as a drop-in replacement. That does NOT mean just any Version 2 gearbox.

Unfortunately, in the past 10 years Airsoft quality control has taken a turn for the worse. What I mean is simply this; Tokyo Marui is what 99% of all the original clones were designed from. When someone clones a gearbox / gun platform and cuts corners to save on cost for both manufacturing and at a consumer lever, there are going to be some differences whether it is tolerance / compatibility or durability issues. From generation to generation, mold to mold, and supplier to cheaper supplier, it’s difficult to adhere to an exact specification or tolerance when coming from China or Taiwan.

I’m sure you have heard the saying: “You can have it good, fast, or cheap – but you can only pick two.” That’s what has happened with many low to mid-end gun manufactures in present years. Demand is up, so they must manufacture faster. Competition is heavy, so they need to give consumers a break (Cheaper). That leaves good (quality) out the window in most cases. In turn, we are left with a market full of AEG’s that claim “V2 compatibility,” but in reality, it simply means I am V2 compatible with my own product line and do not guarantee compatibility with anyone else’s. At this point in time there is no set “standard” or specification for a Version 2 gearbox – or any other gearbox for that matter. That said, just because you have a V2 gearbox in your gun, it does not mean that it’s a perfect, drop-in replacement for other V2 gearboxes.

A good example of this is Classic Army. It seems that a majority of the Revolution problems I see are with this brand. From gun to gun, or receiver to receiver, I am finding that few Classic Army receivers can fit the Revolution V2 Gearbox without modification (Machining internally). This is not so much a generation issue either. We have seen all the generations thus far and they all have fitment issues. I’ve had two new generation Classic Army M4 bodies side by side, and one was a drop-in fit, and the other simply would not. (Please don’t misunderstand me here. I’m not saying that Classic Army is a bad brand, nor am I saying that they manufacture crap. What I am saying is that their tolerances of their receivers both new and old vary dramatically. We see more of these guns come into the RMA department, simply because I believe there are more of them on the market and their price point is typical for Revolution replacement. ) I would also like to add, that we see problems like this with other manufactures as well – Its not just CA. G&P, G&G, ICS, KWA are among the most common. Some fit, and others simply won’t. Right now, I can honestly say that we have had the best luck with the Magpul PTS receivers. So far, they have all been drop-in replacements for the Revolution.

Quote:
2) I would need to buy a Systema Hop-Up unit in order to avoid jams and ensure a perfect seal between the hop-up unit and the gearbox...
Again, due to tolerance issues, as of right now I can say that we are only able to achieve a proper air seal with a SYSTEMA hop-up chamber and bucking. On a different note, We do not recommend "hard" buckings to be used with the Revolution. Hard buckings are typically known for causing BB' jams in sub 500 FPS AEG's because there is not enough pressure to effectively pass the bb through the chamber. (Read more bleow on BB jams and the Revolution).

Quote:
3) I would need high quality magazines. The suggestion I was getting from everyone (Including Wallace @ Systema) was to use Magpul Pmags. A slightly bigger problem.
So far we have not found any hi-cap magazines to work well with the Revolution. Magpul PTS, an Tokyo Marui magazines have worked flawlessly on our demonstration gun.

Quote:
4) I am a sucker for Crane stocks. Period. I was informed by Wallace that the Revolution wiring (because of the fuse if I recall) would not work with a crane stock because the wiring could not pass through the small space needed to enter the buffer tube.
Yes, unfortunately this is the case. We have seen some custom alterations to make this work, but modifying the circuit will void any warranty.

I don’t believe we have ever had a gun in our possession for 6 months. IF we did, I apologize for this. I’m going to send you a PM on this matter. The longest we have had a gun is 2 months – and that was because we were waiting for replacement parts from Spartan Imports. Our typical turnaround time is 2 weeks unless it’s during the holiday season.

I can’t talk about this enough. 50% of the guns that come in to our shop for RMA are damaged as a result of the installer over-tightening the rear stock bolt that attaches to the spring guide. The other 50% is caused by a misaligned gearbox in the receiver, or a BB jam.

One – The gearbox is not installed correctly and is misaligned within the body, or simply the fact that the gearbox is not compatible with the body it was installed in. This misalignment causes a restriction in the nozzles movement or travel. This happens because the nozzle can no longer travel to its “home” or forward position. If the gearbox is cycled with the nozzle not in its home position, the will gears cycle, and it will create a timing issue that can cause a catastrophic failure within the gearbox. Usually the failure point is the rack gear as well as the sector gear and nozzle.

Two – A BB Jam. (Note: Any time a BB becomes jammed within an AEG, it is never a good idea to continue to fire the weapon). When a BB is lodged in the barrel / hop-up chamber, it will create the same problem as issue one. The jam prevents the nozzles movement or travel back to home position. With the Nozzle stuck at a half-way point and unable to move forward, Cycling the gearbox when a BB jam is present can also cause a catastrophic failure. Also, the failure point will be not only be the nozzle, but also the rack gear and possibly the sector gear.

Where would you install the shims on the bolt? Thanks for this piece of information. I dont think the bolt is overly-tightened, but it is a very good thing to be aware of.

Would you recommend a Magpul PTS reciever then, even if (as in my case) the reciever has already been milled to fit the Revolution?

Hillslam mentioned that installing shims on the rear tightening bolt helps with this problem. Are there any other recomendations for this, besides blatently over-tightening the bolt?

Thank you both for your replies, they were very helpful.

He's talking about putting in some shims behind the gearbox itself, where the stock retention bolt enters the rear of the gearbox. Now, you're not going to be using gear shims. You'll have to make a trip to your local hardware store to get ones large enough to work.

Essentially, adding a shim to the back of the gearbox prevents the gearbox from getting warped out of position after you tighten down the stock screw.

I hope that makes sense.

So basically:

[Gearbox|Shims|Lower Receiver|Stock], with the stock bolt running through all of that?

Correct.

Small fender washers work great for this.

Thank you very much for this info guys. There is probably more good advice and information in this thread than anywhere else on the internet about the revolution. I'm sure what you have written here is going to help out loads of people in the future. (including myself ) THANKS!!

*edit* almost forgot! I've seen comments here and there about the revolution being programmable for 3 round burst... Is this true?

I agree, great info.

And we already show up as #1 for Systema Revolution Review.

Yes, it is possible, but you do so at your own risk. It voids the warrenty, and unless you are reasonably confident in your soldering skills, I would avoid it.

Here are the two pins you need to solder if you are looking for the burst function:

http://www.zshot.com/TB-090108.asp

Again, read what Systema has to say on the matter. The warn that a "High level of skill" is needed to perform this operation. You also have $200 on the line if you screw up and need to buy a new ECU.

In a sense, yes. However, the terminology for the Revolution circuit is not that is is "programmable" pre se. It's actually a much more barbaric approach. In order to achieve the burst function on a revolution, you basically modify the ECU, or Electronic Control Unit with a jumper by bridging two contacts together with solder. The image below displays the two contacts which need to be bridged

http://www.zshot.com/ShowPhoto.asp?P...090108-01L.jpg

This procedure is considered a "hack". It is not supported by SYSTEMA, nor ZShot.com - we only post it here for educational / reference purposes. In fact it is not even acknowledge by SYSTEMA. ONLY APPLY AT YOUR OWN RISK!

This procedure involves removing, and modifying the main circuit. It requires a very high level of skill, as well as the correct equipment. If you do not have any "surface mount" experience, DO NOT ATTEMPT. If you have to ask what "surface mount" is, DO NOT ATTEMPT. If you cannot risk $200+ for a replacement circuit (yes... that damn chip is expensive), DO NOT ATTEMPT. If you have ANY doubt what-so-ever (e.g. say one of the picture doesn't match up), DO NOT ATTEMPT

The next question will be: Are the Revolution circuit and newer PTW circuits the same so that you can get burst function on your PTW?

Thats always been the case... We do Burst Modification for PTW's all the time. I've been doing burst conversion since Gen 3.

BounDByLighT,

I apologize, as I completely missed your question earlier. If we machined your existing lower reciever to fit the revolution and sent it back to you that means it was sent to you fully functioning and that it passed all of our internal testing. At ZSHOT, we take pride in our repairs and try to repair any RMA properly the first time.

That said, your guns receiver should no longer be of any issue or concern. Now if you would like to change receivers in the future, I do highly recommend the Magpul PTS upper & lower receiver combination. Based on previous experience internally, we have found those to be one of the only drop-in replacements on the market, besides the now discontinued SYSTEMA Receivers. However, dues to the fact we have no control over Magpul PTS’s manufacturing standards, a newer batch of those receiver may vary.

Now, I’m going to be perfectly honest, I was very surprised that the DBoys upper & lower receiver was a perfect, drop in replacement as well. If I were a gambling man, I would have automatically ruled a receiver like that out. But it fit like a charm. However, please keep in mind; the only experience we had was with the one set that Hillslam provided to us. Other samples of the same body may also vary.

We have not had any experience with the Revolution and compatibility with King Arms products as of this time.

I currently have a stock marui gearbox with very little upgrades, and everyone keeps telling me to "never replace anything in it" and "it's amazing as it is" I know marui is a good solid gearbox, and my gun is shooting great, but i feel it could be better. What i want to to know is, would the revolution gearbox be a smart investment?

In my opinion, no. I've had nothing but trouble out of my Revolution, and the same goes for a few other guys in the state who have them (5 out of 5 of us have issues). They're quite expensive to fix, and support is very hard to find.

FYI I'm in SC, not Ohio.
