Great first pic! Looks like DDC was made to match Colt FDE.

Here's some (bad) pics of my green 13.5" MK16 and ACH. They look kinda tanish in the pics, but in person they're a super pretty green anodizing.

@GACS @sagmill

Any word on how many of the black, gray, and green were made in each length?

Any pictures of rails getting made, in the white, etc.?

Any info on the ID, width, or weight of the 9.3"?

DDC versus green. They look beautiful together.

Both the green rail and charging handle are both NSN marked, as well.

I'm not a photographer, but my OD Green MK16 kit came today as well. I agree the photos don't do it justice; the green is amazing. I wish I could have purchased an ODG 9.3" MK16 along with the DDC I got.

My guess would just be the number of rails available. Probably more 13.5s to go around so they did more colors. Probably figured black and DDC are their main colors and probably the most popular so just did the 9.3" in those colors.

The grey is beautiful. All the colors are. I have to give it to Geissele and their anodizing. It's a step above most. The grey ACH is a bit lighter in shade than the rail, but still looks great.

Agreed and maybe someday Geissele will offer matching receiver sets.  Are you gonna build all 3 rails into uppers?

Green Mk16 kit and Mk4 Federal showed up yesterday. Immediately swapped out my Mk14 DDC for the Mk16. I'm a big fan.



Lots of other Geissele goodies here too....

The grey and black are a friend's and the DDC and green are mine. Obviously, the DDC is already built and I'm unsure of what I plan on doing with the green. I ordered it because I've wanted a green Geissele rail ever since I first saw the FBI MK4's and couldn't resist having a green 13.5" MK16. Just need to figure out whether I want to build another rifle around it or not. Lol

ODG Mk4 in the sunlight. It's definitely much darker than my Mk16, and has more of a gloss to it, whereas the Mk16 is more matte. Very pretty either way.

Until the form 1 approves, hoping for another 11 day return. Still needs KAC BUIS, and a few other things. RC2 should be out of jail next month. Lighting sucks today because it’s really cloudy, will take some better pics tomorrow. Can’t wait to shoot this Sunday!
