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…
