I have a build that is mostly Geissele parts except the barrel. I'd like to make it an 8 inch .300blk with a Geissele rail. I found a 7" black rail but I need DDC for this build. Are these ever going to be available again?
If my wife had another baby and I was in the delivery room, I'd probably look at it and yell "welcome back bitch" and then have the hospital page Norcal. -scuba_steve

Primary Arms had both black and DDC 7" MK4's the other day. As of yesterday when I looked again the DDC was OOS though.

I saw the black on sale so I went ahead and snagged one. Didn’t see the DDC at all. There are no 7 inch rails listed on Gs website. Are these made specifically for PA?

Geissele had them on their site for a while about a year ago. I think they are like ODG. Every now and then they'll make a run of them.
