I am putting together a parts list for an 18" rifle length precision ar-15 build and I am really stumped on trying to find a good quad rail that is long enough to cover the gas block... I think the only thing that comes close or may fit the bill is LaRue... Anything else out there?

I put a Strike Industries GridLock on my 18 inch gun with rifle gas. It seems fairly solid to me so far. I have shot out to 600 with the setup.

Larue's longest quad-rail is their 13.2" version. It doesn't cover a full-length gas block, but comes close for a ~1" gas block.
....
Midwest Industries has 14" and a 15" options.

Nice, got any pics?
I have 6 or 7 MI rails on various ar15s but I want something with a more rigid lockup for this precision build.
That's definitely an option but it drives me nuts that they don't offer the ris ii in a 14-15" length... That would have been my first choice.Daniel Defense 15.0 DDM4 rail

Just this one handy. Will snap a side view when I get home and make my way out to the shop.
Looks badass, love the rattle can, I am looking for a quad rail for this build though
I considered a MK16 or MK4 but my heart is kind of set on a full quad rail.

As far as I’m concerned the MK18 Geissele rail is the best there is for a precision build. They’re usually out of stock and hard to come by but there’s one listed for a good deal currently.

What size journal at the gas port?
I have a few heavy/long barrels that have a 0.936" gas port and an adjustable gas blocks won't fit under the rail.

Good reminder, I looked at that one a while back, I don't own any ARCA stuff so it wasn't that appealing at the time, but I do see the appeal to having a flat bottom... I bet it would be a lot more stable on a front bag.As far as I’m concerned the MK18 Geissele rail is the best there is for a precision build.

Penciled in a CLE Bartlein, should be .750, haven't ordered it yet.
There’s nothing more stable on a bag than a flat bottom. If you want more stable you put a grey ops plate on the arca rail. It’s beneficial even if you don’t use it to mount it to a tripod or bipod.
