I ordered one of the new Inforce Weapon Mounted Lights
from GG&G on Monday, it arrived Yesterday and I have to say, so far so good.
It is all plastic, but it was thick plastic seemed very, very solidly built, it seems quite rugged and I like the big swing-up switch lockout, pretty idiot-proof. It mounted to a rail on a Troy hand guard easily. I took it off and replaced it a few times to test the mounting system a bit, it works well. One strange thing, every time I mounted it, it would shift once just a tiny bit when pushed, and then didn't budge. I don't think it's as "combat-tough" as a Larue mount or the like, but the slim profile of the light makes it way less likely to bump into things in the first place.
The light was, well, it was a pretty typical bright-ass LED light... pure white and a very "clean" beam. The switching/strobe functions worked just like the manual said they should. Mounted at 9 o'clock in conjunction with an AFG, the switch falls easily in reach of the support hand thumb, and the light housing itself makes an excellent "shelf" for the thumb when not using the light. I love the lockout device: no fancy electronics, just a big hunk of plastic that swings up in front of the switch when you want it and tucks neatly out of the way when you don't
All in all, I like the light. At about $150, it's priced pretty competitively with comparable products, and is much more "streamlined" than most systems. I will probably buy another one or two for other guns.

Congrats on the light.
Rick from Tactical LEDs gave a few of us members the oppertunity to field test some of the lights.
Here is the two links from the industry fourm.

I really did like the light and have one of the prize lights on my M&P15 now.
Take a few mins to review the test.

I have the non-IR version and really like it. Very light weight, acceptable output from a single battery, and mode options are a plus, especially the "low" mode for navigation.
I like mine. Where the light really shines, imho, is if you require both white light and IR capabilities. It's awesome being able to have both features on one compact little light without needing to screw with filters or anything.
I've been doing a demo with the light as well I'm impressed so far. Here's what I had posted at FN Forum

Some decent pics
I was looking at one of these, but Greg3's review showing how the front bezel cracked put a nix to that. Wish some of the big boys would come out with a similar design...
