The (Theoretical) LSHD Signature Carbine Package

[Unobtanium]

Yeah, if you feel that you have a need to light up something at 75 yards outside then I would say a powerful incan is a great idea. If you think a more realistic use for the light is mainly indoors or inside 25 yards the LEDs are great. If you live in an environment that tends to have high humidity or rain I'd say the incan might help outside.

Haha, I just saw the post-date on this. Amazing how much things have changed in just 2 years, isn't it? I think the only thing that changes faster than LED technology are iPhones getting longer. I remember E-mailing Gene Malkoff a few years back asking about a 300 OTF lumen 2-CR123 single-die light. He said sadly it couldn't be done, and 230 OTF or so was about it. Now we have 800+ OTF lumens from that combination. Heck, factory Surefire lights are 500+.

Blast from the past! I'll detail the carbine that I'm using right now:

BCM LW 11.5" upper
10" KMR handguard
BCM BCG
BCM GF Comp
BCM GF Ambi CH
Troy folding BUIS
Trijicon SRS
SF M300 Mini Scout light
BCM lower
GF Mod 3 grip
Geissele S3G trigger
VLTOR iMod stock
VLTOR A5SR Receiver Ext.
A5H4 buffer (6.83oz)
BAD-ASS ambi safety
SOB sling

Remarkably similar to what I just out together. The places where our choices deviate (I'm using a different trigger and sights) the functionality of those parts is pretty much identical (I'm using a CMC trigger, the Diamondhead-made BCM sights, and an Aimpoint PRO). I'm also using one of the new, tan, X300s because I still can't bring myself to keep any light on any gun all the time.

What are your thoughts about the kmr compared to the carbine laid out in the OP? I'm in the market for an upper for home defense. I've all but decided on a 14.5" carbine gas system with a front sight post for ultra reliability given the intended use, but the kmr does seem to be really popular. Makes me wonder if I'm missing something.

The KMR is pretty awesome.

FYI: looking at my first AR and was using this as a guideline. BCM no longer makes LW carbine uppers in 14.5 or 16, only 11.5. The longer LW's are all mid-length.

I noticed that. I suspect they might come out in dribs and drabs. I'm pretty sure you can order a DD upper in a 14.5" pinned carbine format.

The KMR makes my Troy Alpha feel fat and unwieldy.

Here's what they sent:
"Carbine gas system upper receiver groups are only available in government profiles.* Mid-length gas systems are available in lightweight, stainless, enhanced lightweight as well as government profile barrels."

Makes it sound permanent, but who knows.
It's tempting me to go with the 11.5 and do a pistol build.
