Your correct on the first pic....it's a 15" SMR MK1, and a 18" barrel.
The second pic...it's a 13" SMR MK1, and a 14.5" barrel.
hunt_ak....could be the picture to some degree, however in terms of feel, the MK1 feels like a totally different rail in your hands imho. The MK1 does have a rounded profile as opposed to the MK2's flat sided one due to how they mount up their respective acc. rail panels. I do think it's safe to say that the MK1 is thinner by at least some margin. I would measure for you pal, but I recently sent the Sand MK2 back to GA.
Hopefully next week we will hear news on the new lightweight models. It's my understanding at this time that all future rails will be coming in a newer lightweight configuration. I imagine they will still appear and function the same, just have weight removed from places.

So 15" rail is too long for a 16" mid length with a SF brake??

I don't see any reason at all that a 15" SMR wouldn't work perfectly with a 16" middy, moreover, if I was to build another 16" AR upper today, it's exactly the rail I'd use. Originally I had planned to build a Recce (16"/mid/medium contoured) upper with the 15" SMR, but ultimately I received a SPR barrel that was just too nice to not go with instead.
Perhaps my SPR/M4 blackout on the 15" SMR upper of mine is throwing you off a bit, it indexes quite a bit over the barrel when installed so it makes it hard to tell where my rail ends, and where the actual barrel then ends.
Here is a pic that should help maybe clear that up a bit...

Here are some pics of my Geissele MK II Rail. Still finishing the gun but I wanted to some more shots of the Geissele rail for others to see.
Still need a flash hider, back up sights etc.. but this give you a gist of the 13'' rail on a 16'' med contoured barreled AR.

Bummer! Thanks for the offer, though. I was going to PM you about sending an FDE anodized upper your way just to see how they look side by side, but I guess not! So who do I call at GA to get that 'blem' rail?

Wow, that makes the sand look way more brown than normal...is it just the picture?
I've got an FDE receiver set that's looking for a 'matching' friend...

The Geissele is more brown than tan ( Which I like) . Its more mor ebrown like the Daniel Defense RIS II.
You receiver looks great.

Gotcha. Somewhere between Magpul FDE and DD FDE? Do you have a RIS II to take a picture next to?

Awesome build SRT-M4
I've found that the Sand blended more naturally into the background over Magpul's FDE. It changes color depending on what light conditions are present as well. It's the richest ano finish I've ever seen.
Here it is in a more natural environment, and how it blends with the magpul FDE...
