Update to my MGS4: M4 Custom Project.
OMFG. Words cannot describe my level of frustration. Selecting the JG M4 S-System as my base gun was probably the worst possible thing I could have done.
In short, I’m better off building the gun from scratch.
After disassembling the SIR front-end, receiver, and trying to comprehend how I’m ever going to attach the S-System’s proprietary outer-barrel to my D-Boys Metal Receiver - I gave up. Instead I found someone who had a lightly used CA M15-A2 (I believe) outer barrel. The model without the notch for the grenade launcher. Which is probably what I should’ve done to begin with, as the original 3D Render I was working from doesn’t have that notch anyways. So, all is good in the world. Right.
Back on topic… now that I’ve decided to keep the S-System intact, I needed a new source for some internals. Luckily for me, a good friend of mine operates the Xtreme-Tactics Online Store. He was able to hook me up with some parts I needed (i.e. inner-barrel, hop-up rubber & bucking) at a good price. So now there is a Mad Bull Black Python 363mm tight-bore installed, with a CA hop up rubber and bucking.
The CA hopup rubber seems a little thicker than TM ones I’ve used in the past, but with a little lube (silicon oil, you perverted bastard), it slid on in without a problem.
I still have to make a decision as to where I’m going to put the battery. Eddie from CRW-Airsoft told me he has his (3-cell Firefox 11.1v 1200mAH LiPo) in the RIS system he used (not the same free-float RAS I’m using), but that the same bettery would fit in the stock buffer tube. I have this battery and with some slight modification to the lower-receiver it will fit. So here are my options:
- Rear-wire to the buffer tube. Safe, hidden, adds some rear-weight (albeit not much, the LiPo is incredibly light).
- Front-wire to the RAS. There is a possibility the battery could be struck by a BB through the holes inthe RAS. While you would need an incredibly hot gun to damage the battery to the point of catastrophic failure, I’d rather aire on the safe-side. But this is an option.
- Front-wire to an AN/PEQ unit. If I can find one that has a buildt-in laser for cheap - then that’s an added feature I suppose. But it will add more weight to the front-end of the gun, and PEQ units aren’t to everyone’s tastes.
I’m open to suggestions, or other alternatives if you have any ideas. Register (don’t worry, you won’t be added to any mailing lists, it’s against the law here), and post in the comments.
So while I have the gun assembled, albeit incomplete, here are a few photos. I apologize in advance for the shitty camera work, I blame my iPhone. I’ll get better pics up when my Sony is charged.
Cosmetically; I’m still missing the front-sight. I opted not to take the one off the S-System to leave the gun intact.
Internally; I need to decide on a wiring scheme (front/back), I’d like to install a Trigger Master to control the LiPo (update coming soon on this review as well), and I need a motor (again, I’m not using the S-System’s).
So, I’ll have another update shortly, as soon as I get a front-sight and motor in.
Until then.

UPDATE #2:
I got the SCAR-H in yesterday - the fastest shipping of an AEG in recorded history, I swear. Well, for me, anyways. Thanks goes out to MOPIC for getting it to me blazingly fast.
The original intention of the Trigger Master was to go into my MGS4 M4 Custom project, however I’ve decided to put a Systema Revolution gearbox/motor in it instead. Well, whenever the bloody thing is released, that is.
Why I chose the SCAR-H for the Trigger Master
The SCAR-H and SCAR-L are notorious for not being able to fit a large battery. An 8.4V mini gives the AEG a terrible rate of fire, and the motor sounds like it has to spin up for almost a second on a semi-auto trigger press. I plan on installing a Li-Poly 11.1V 1200mAh battery instead of the conventional 8.4V mini (and upgrade any mechbox internals as necessary), and one of the main selling points of the Trigger Master is that it can control battery consumption, and has a low-battery warning. Because LiPo batteries are sensitive to over discharge, this is a perfect solution to solve the battery problem on a SCAR, while giving yourself the benefits of computer-controlled fire and 3-round bursts.
The “Unboxing“
OK, it wasn’t shipped in a box, but a cardboard envelope. No big deal, right? You tell me. The circuitry hopefully isn’t sensitive to static discharge, because it was shipping in a Ziplock bag, and not a static bag.
Other than that - the documentation included is minimal. Installation guide can be found online here for an M4, or here for an AK. I’m installing the Trigger Master on a SCAR-H (same as an SR-25) and there are no specific instructions for a SCAR-H or SR-25, but the example for the M4 is close enough to what I’m looking for. But that’s the next part of the review.
It would have really been nice to see a hard-copy of the Full Documentation ( <– PDF link) included, so I have a portable record of how to configure the unit on-the-fly. So be prepared to print one off yourself, unless you have a photographic memory and can memorize the programming instructions.
Maybe I missed it, but I’m also looking for the initial “setup”, or “training” instructions for the unit. Once installed, the unit mut be “trained” to your gun. Those instructions are not included, as far as I can tell. These would have been VERY useful - and are included in the Full Documentation. So again, you’ll want to print a copy.
Shipping
Shipping costs are reasonable, packaging is sufficient, and shipping times are acceptable (not out of the ordinary).
First Impressions & Summary - Pre-Installation
First thoughts are fairly positive. Looks good, has lots of extra wire to ensure proper and easy installation. Documentation would be great, but is not shipped with product. Cost is reasonable for what the product offers, and shipping costs are standard.
Next, is the installation…

It should be noted for those keeping score at home, I received my Trigger Master unit on Friday. Hooray!
But wait. I don’t have the gun I’m going to install it on.
The gun is a CA SCAR-H, purchased from a local (Canadian) retailer. Just awaiting on it to arrive, and the review shall commence.
Thanks to Don at Unconventional Airsoft for the fast shipping.

With the (ever) impending release of the Systema “Revolution” electronic fire-control mechbox, I decided to try a few other fire-control systems before this one comes out.
From Unconventional Airsoft (local in Canada), the Trigger Master AEG Fire Control Unit promises to offer the following:
- 3-round burst which becomes full-auto if the trigger is held down.
- Full computer controlled MOSFET driving of AEG motor, with active braking.
- Overcurrent protection (the unit can safely replace the AEG fuse)
- Ease of installation (the unit is the same size as a standard fuse holder)
- Full PWM motor control to maintain a constant performance, and reduce motor and drive train stress.
- Firing modes, burst timing, and rate-of-fire are all programmable by the user.
- Thermal protection (temperature monitoring, notification of user of overtemperature condition)
- Over- and under-voltage protection and warning.
- Open sourced hardware and software design allowing modification and upgrades if you so wish.
- Custom programming and features available from Unconventional-Airsoft.
The unit is on order, and should be here shortly. I’ll begin the review with the installation process.
My vantage point is from that of a novice AEG upgrader (I’ve done gearbox dis-assembly, and re-assembly - successfully, I might add), but limited gearbox/AEG electrical work. While I’m not afraid to get my hands dirty & improvise where necessary, I can definitely follow a set of instructions - which will be reviewed as well.
It’s my firm belief that any airsofter that know his/her way around a gearbox should be able to install an upgrade like this - so we’ll put it to the test.
