Both rails seem to be top performers but is there something that sets one apart from the other? BCM wins in weight and in price, but what makes the Geissele a competitor? Any insight into what sets these rails apart would be appreciated.

I think it's personal preference more than anything. I have both and slightly prefer the KMR. I think the Geissele is slightly more solid and well built but you sacrifice weight. The KMR has a better feel to me which is why I prefer it.
I prefer the handguard mounting system on the KMR and also the weight advantage of the KMR. Geissele appears to be more popular in SF community.
Geissele mounts in a very similar fashio... Bbl but requires no indexing
No indexing required is a similarity but pretty different other than that. Geissele takes the cake IMO, the most solid lockup in the handguard market. Theres something to be said about the KMR's cross bolt positioning and how pressure is applied uniformly though, just haven't seen much about it in terms of actual perceivable advantages. The Geissele rail's robustness for lack of a better word and securing features of the rail to the upper give it the nod in my experience.
Science vs badassery lol.
I own a few of both and prefer the Geissele. If weight is even the slightest concern, the KMR takes the cake. The Geissele looks and feels more solid. Even though I have had no issues with either. I do like the mounting system to the upper on the Geissele better. The anti rotation allens in the sides of the rail, are a better system in my opinion then the metal tab at 12.oclock on the KMR. I have had a KMR that was so tight, that I could not get the top rail to line up flush with the upper perfectly. If fit up to the upper, but would not turn the slightest amount to line the top of it up flush. It was close, but enough so the irons were off. Almost had to max the rear out to one side. Looking down the 12 rail, you could see a slight tilt. Had to bent the tab out, so there was a little wiggle room on the to rotate the handguard. This is a non issue for the Geissele. The Geissele just feels more solid and better built IMO. And the Geissele Scout mount for there 45 sections is the best and easiest way to directly attach a 45 mount for the scout. It also comes with 3 height options. This is the best scout mounting system IMO. The Geissele takes the cake in my book. Just my .02 and others might have a different experience..
KMR is bomb proof, Geissele is bigger bomb proof. If you want something lower profile and lighter weight, the KMR is the better choice. If you want something a little beefier (but still pretty light considering) that could double as a blunt force weapon, can't beat the Geissele.
Unless the weight savings is very important to you, I'd vote the Geissele. There is no better rail system on the market in my opinion. The mounting system, anti-rotational tabs, aesthetics, weight. Perfect in every category.
In currently running a 18oz 10" rail so either rail is a decrease in weight. It looks like the general concensus is bcm for weight saving and geissele for robustness.
Does anyone have a lead on the SMRs in stock?

Do you mean Geissele triggers or SMRs being popular in the SF community? I know the triggers are being used but I didn't know about the rails. I'm not challenging the statement, I just don't have any info on the subject. Anyone have any pics?
And I already use SMRs so I'm not looking to buy something the big boys use ha ha. Just looking for a little knowledge.
Geissele originally designed the SMR to fulfill a contract issued by the DoD for replacement HK416 rails.
All current SMR rails offered for the AR15 grew out of that original contract.
You're likely to not see many pics of the HK SMR rails in the wild given who is currently using them.
Mr. Geissele talks about the HK rail, and the "organization" that uses it briefly in the video below....I'd recommend the full watch, but the rail stuff starts at the 16min. mark.

Without getting into the whole KEYMOD vs M-LOK debate, I simply prefer the aesthetics of the M-LOK. And with my intended uses, any supposed inferiority of M-LOK will still be much greater than my demands.
And I think this rifle is what I've tried to envision in my head for a long time.

I only feel somewhat skeptical about putting a $300 rail on a $1k Colt 6920.
I ordered a SMR MK5 on Friday and it should be in by the middle of the week.
I think we all know what (and who) he's talking about.
I've had vets think that when I say "SOF" that I mean "Soldiers of Fortune" not "Special Operations Forces" and then tell me that I mean "SF"... at which point I have to explain that for some folk "SF" - meaning Special Forces - can only apply to US Army Special Forces, aka Green Berets. I've found it to be especially true with European allies that when they say "US SF" or "American SF" they don't mean US Army Special Forces exclusively, but practically every unit under SOCOM (plus the super secret squirrel ones).
